　View Summary

The projection technique that realizes projection mapping used in many events has been studied for a long time as a projection display in the field of spatial augmented reality. As this projection display technique, we proposed two techniques;one manipulats the appearance of the real worlds and other displays viewpoint dependent appearance using a light field projection. In this paper, we introduce our successive manipulation technique of translucency and glossiness based on cognitive science with a co-axial projector-camera system. In addition, we introduce the material perception projection technology we have worked on, such as a structural color display using projector arrays and material perception editing using multiple projector-camera systems.

　View Summary

This paper proposes a method for gaze navigation in the real world by projecting an image onto a real object and changing its appearance. In the proposed method, a camera captures an image of objects in the real world. Next all the pixels in the image but those in a specified region are slightly shitted to left and right. Then the obtained image is projected onto the original objects. As a result, the objects not in the specified region looks blurred. We conducted user experiments and showed that the users' gaze were navigated to the specified region.

　View Summary

Fluorescence can be a beneficial property not only for the scene analysis, but also for a spatial augmented reality (SAR). In the field of SAR, the projector camera system has been well studied and its radiometric model can be described by a color mixing matrix. For the measurement of the color mixing matrix, special equipments other than a projector and a camera are not required. The fluorescent components are not separated by the color mixing matrix, but it already has a capability of handling light emission of fluorescent. In this paper, we propose the RKS model that expresses fluorescent components as well as reflectance components from the approximation of the Donaldson matrix. In addition, we propose a decomposition method of the color mixing matrix. Experimental results show the decomposition of color mixing matrices obtained from color construction papers and non-fluorescent Kent papers with several fluorescent paintings. Then, we demonstrate separation of reflectance and fluorescent components of a scene. We also demonstrate effectiveness of radiometric compensation that considers fluorescent components.

　View Summary

We present a method for focal distance estimation of a freelyorienting eye using Purkinje-Sanson (PS) images, which are reflections of light on the inner structures of the eye. Using an infrared camera with a rigidly-fixed LED, our method creates an estimation model based on 3D gaze and the distance between reflections in the PS images that occur on the corneal surface and anterior surface of the eye lens. The distance between these two reflections changes with focus, so we associate that information to the focal distance on a user. Unlike conventional methods that mainly relies on 2D pupil size which is sensitive to scene lighting and the fourth PS image, our method detects the third PS image which is more representative of accommodation. Our feasibility study on a single user with a focal range from 15-45 cm shows that our method achieves mean and median absolute errors of 3.15 and 1.93 cm for a 10-degree viewing angle. The study shows that our method is also tolerant against environment lighting changes.

　View Summary

Previous research showed that the separation of direct and global components could be done with a single image by assuming neighboring scene points have similar direct and global components, but it normally leads to loss of spatial resolution of the results. To tackle such problem, we present a novel approach for separating direct and global components of a scene in full spatial resolution from a single captured image, which employs linear basis representation to approximate direct and global components. Due to the basis dependency of these two components, high frequency light pattern is utilized to modulate the frequency of direct components, which can effectively improve stability of linear model between direct and global components. The effectiveness of our approach is demonstrated on both simulated and real images captured by a standard off-the-shelf camera and a projector mounted in a coaxial system. Our results show better visual quality and less error compared with those obtained by the conventional single-shot approach on both still and moving objects.

Gaussian Light Field: Estimation of Viewpoint-Dependent Blurfor Optical See-Through Head-Mounted Displays

IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS ( IEEE COMPUTER SOC ) 22 ( 11 ) 2368 - 2376 2016.11 [Refereed]

　View Summary

We propose a method to calibrate viewpoint-dependent, channel-wise image blur of near-eye displays. especially of Optical See-Through Head-Mounted Displays (OST-HMDs). Imperfections in HMD optics cause channel-wise image shift and blur that degrade the image quality of the display at a user's viewpoint. If we can estimate such characteristics perfectly, we could mitigate the effect by applying correction techniques from the computational photography in computer vision as analogous to cameras. Unfortunately. directly applying existing calibration techniques of cameras to OST-HMDs is not a straightforward task. Unlike ordinary imaging systems. image blur in OST-HMDs is viewpoint-dependent. i.e. the optical characteristic of a display dynamically changes depending on the current viewpoint of the user. This constraint makes the problem challenging since we must measure image blur of an HMD, ideally. over the entire 3D eyebox in which a user can see an image. To overcome this problem. we model the viewpoint-dependent blur as a Gaussian Light Field (GLF) that stores spatial information of the display screen as a (4D) light field with depth information and the blur as point-spread functions in the form of Gaussian kernels, respectively. We first describe both our GLF model and a calibration procedure to learn a GLF for a given OST-HMD. We then apply our calibration method to two HMDs that use different optics: a cubic prism or holographic gratings. The results show that our method achieves significantly better accuracy in Point-Spread Function (PSF) estimations with an accuracy about 2 to 7 dB in Peak SNR.

Appearance Manipulation for Whole Circumference by using Projector Camera Systems

日本バーチャルリアリティ学会論文誌 ( 日本バーチャルリアリティ学会 ) 21 ( 2 ) 363‐371 - 371 2016.06 [Refereed]

　View Summary

In this paper, we investigated the stability of successive omnidirectional appearance manipulation for the multiple projector camera systems without synchronization between systems. This type of system comprises several surrounding projector camera units, where each unit projects illumination independently onto a different aspect of a target object based on feedback from the projector cameras. Thus, the system can facilitate appearance manipulation from any viewpoint in the surrounding area. An advantage of this system is that it does not require information sharing or a geometrical model. However, this approach is problematic because the stability of the total control system cannot be guaranteed even if the feedback system of each projector cameras stable. Therefore, we simulated the feedback from the behavior of projector camera systems to evaluate its stability. Based on hard ware experiments, we confirmed the stability of omnidirectional appearance manipulation by using two projector camera units in an interference condition. The results showed that the object's appearance could be manipulated throughout approximately 296 degrees of the total circumference of the target object. Furthermore, we put into practice whole circumference of the object by using a plate mirror.

Algorithm to Compensate the Time Delay for the Appearance Control System using Camera and Projector

システム制御情報学会論文誌 29 ( 2 ) 93 - 100 2016.02 [Refereed]

　View Summary

The appearance control system is one of the visual feedback control systems that can manipulate the appearance of an object by using a projector-camera system. This system processes the captured image and projects the image on the object overlappingly for manipulating the appearance in real time. However, the afterimage is caused by a part of the image which is not overlapped on the object and remains in capture range of the camera. Therefore, this afterimage makes the appearance control system unstable. In this paper, we propose a new projection algorithm that can compensate the time delay for the appearance control system.We verify the effectiveness of our algorithm which can suppress the influence of the afterimage against the time delay in the visual feedback loop.

Semi-Parametric Color Reproduction Method for Optical See-Through Head-Mounted Displays

IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS ( IEEE COMPUTER SOC ) 21 ( 11 ) 1269 - 1278 2015.11 [Refereed]

　View Summary

The fundamental issues in Augmented Reality (AR) are on how to naturally mediate the reality with virtual content as seen by users. In AR applications with Optical See-Through Head-Mounted Displays (OST-HMD), the issues often raise the problem of rendering color on the OST-HMD consistently to input colors. However, due to various display constraints and eye properties, it is still a challenging task to indistinguishably reproduce the colors on OST-HMDs. An approach to solve this problem is to pre-process the input color so that a user perceives the output color on the display to be the same as the input.
We propose a color calibration method for OST-HMDs. We start from modeling the physical optics in the rendering and perception process between the HMD and the eye. We treat the color distortion as a semi-parametric model which separates the non-linear color distortion and the linear color shift. We demonstrate that calibrated images regain their original appearance on two OST-HMD setups with both synthetic and real datasets. Furthermore, we analyze the limitations of the proposed method and remaining problems of the color reproduction in OST-HMDs. We then discuss how to realize more practical color reproduction methods for future HMD-eye system.

　View Summary

A co-located projector camera system where the projector and camera are positioned in the same optical position by a plate beam splitter enables various spatial augmented reality applications for dynamic three dimensional scenes. The extremely precise alignment of the projection centers of the camera and projector is necessary for these applications. However, the conventional calibration procedure for a camera and projector cannot achieve high accuracy because an iterative verification process for the alignment is not included. This paper proposes a novel interactive alignment approach that displays a capture of the projected grid pattern on the calibration screen. Additionally, a misalignment display technique that employs projector camera feedback is proposed for fine adjustment.

　View Summary

This paper presents a fast simulation method for turbulent flow which uses a particle method and wavelet analysis. To simulate fluid flow, the method uses smoothed particle hydrodynamics (SPH), which discretizes the fluid into a collection of particles, and detects regions where turbulent flow will occur by using wavelet analysis without a spatial grid. By taking the curl of wavelet noise, the turbulent flow is then appended as a divergence-free turbulence velocity field. Additionally, by using a particle splitting, which characterize the vortex features of turbulence, a sub-particle-scale representation of turbulent flow is proposed. Implementing almost all processes on a graphics processing unit (GPU), simulations are performed in near real time.

Proceedings - 2012 14th Symposium on Virtual and Augmented Reality, SVR 2012 ( IEEE Computer Society ) 246 - 253 2012 [Refereed]

　View Summary

This paper addresses the problem of tracking textureless rigid curved objects. A common approach uses polygonal meshes to represent curved objects and use them inside an edge-based tracking system. However, in order to accurately recover their shape, high quality meshes are required, creating a trade-off between computational efficiency and tracking accuracy. To solve this issue, we suggest the use of quadrics for each patch in the mesh to give local approximations of the object shape. The novelty of our research lies in using curves that represent the quadrics projection in the current viewpoint for distance evaluation instead of using the standard method which compares edges from mesh and detected edges in the video image. This representation allows to considerably reduce the level of detail of the polygonal mesh and led us to the development of a novel method for evaluating the distance between projected and detected features. The experiments results show the comparison between our approach and the traditional method using sparse and dense meshes. They are presented using both synthetic and real image data. © 2012 IEEE.

Content printed on the paper media is not rewritable, but its appearances can be controlled by illumination. In this paper, we propose a new method to represent three-dimensional (3-D) shape on the print media by the shading animation using projector-camera feedback. The proposed method consists of a hue, saturation, and value (HSV) map and an appearance control technique, and these are key technologies. The HSV map represents a normal map of the 3-D content, and it is embedded in the printed media by full color print. While the system is projecting a shading animation for the 3-D representation, the embedded information is decoded by modulation estimation using the appearance control technique. © 2012 IEEE.

　View Summary

本論文では，既存の時系列パターンマイニングアルゴリズムPAIDを対象に，CPUのキャッシュミスの軽減による処理時間の短縮を目的とした改良手法の提案を行う．時系列パターンマイニングでは，データベースの規模やパターンの抽出に用いられる閾値によって非常に長い処理時間が必要とされることが問題とされており，過去の研究においてアルゴリズムや並列化の提案が行われてきた．また，処理対象となるデータベース全体に対して多くの反復的なアクセスが生じ，キャッシュミスが発生しやすいため，大規模なデータベースや小さな閾値を利用した場合，そのレイテンシは全体の処理時間に対して無視できない可能性がある．PAIDアルゴリズムにおいても同様に反復的なアクセスが生じるデータ構造があり，キャッシュミスが起こる可能性が考えられる．そのため，提案手法では処理対象へのアクセスパターンの改良により，PAIDアルゴリズムの特定のデータ構造での時間的局所性を向上させ，キャッシュミスの軽減を行う．また，処理時間を短縮するために並列化も行い，性能評価によりこれらの有効性の確認を行う．In this paper, we propose a technique to reduce the memory access latency caused by cache misses in PAID algorithm. Since sequential pattern mining algorithms generally require long time depending on the database size and the minimum support value, many methods have been proposed such as new efficient algorithms and their parallelization. The sequential pattern mining tends to repeat database scans, which frequently cause cache misses. The frequent cache misses cannot be ignored, when, in particular, a low minimum support value is set. In PAID algorithm, cache misses happen in some data structures which are accessed repeatedly. Therefore, we propose a method to improve the data structures and their access patterns so that temporal locality of reference increases, which leads to more cache hits. In addition, we also parallelize our method to reduce further execution time. We evaluate the efficiency of our method through some experiments.

　View Summary

In this paper, we show that optical inverse tone-mapping (OITM) in light microscopy can improve the visibility of specimens, both when observed directly through the oculars and when imaged with a camera. In contrast to previous microscopy techniques, we premodulate the illumination based on the local modulation properties of the specimen itself. We explain how the modulation of uniform white light by a specimen can be estimated in real time, even though the specimen is continuously but not uniformly illuminated. This information is processed and back-projected constantly, allowing the illumination to be adjusted on the fly if the specimen is moved or the focus or magnification of the microscope is changed. The contrast of the specimen's optical image can be enhanced, and high-intensity highlights can be suppressed. A formal pilot study with users indicates that this optimizes the visibility of spatial structures when observed through the oculars. We also demonstrate that the signal-to-noise (S/N) ratio in digital images of the specimen is higher if captured under an optimized rather than a uniform illumination. In contrast to advanced scanning techniques that maximize the S/N ratio using multiple measurements, our approach is fast because it requires only two images. This can improve image analysis in digital microscopy applications with real-time capturing requirements.

　View Summary

Visual impairment is a common problem for people worldwide. The projector-based AR technique has the ability to change the appearance of real objects, and it can help to improve visibility for the visually impaired. We propose a new framework for appearance enhancement with a projector camera system that employs a model predictive controller. This framework enables arbitrary image processing such as photo-retouch software in the real world and it helps to improve visibility for the visually impaired. In this article, we show the appearance enhancement results of Peli's method and Wolffshon's method for low vision, and Jefferson's method for color vision deficiencies. Through experimental results, the potential of our method to enhance the appearance for the visually impaired was confirmed to be the same as appearance enhancement for digital images and television viewing. © 2010 IEEE.

　View Summary

In this paper, we propose a novel approach using a cyclic group to model the appearance change in all Image Sequence of an object rotated about an arbitrary axis (1 DOF out-of-plane rotation). In the sequence, an image x(j) is followed by an image x(j+1). We represent the relationship between images by a cyclic group as x(j+1) Gx(j) and obtain the matrix G by real block diagonalization. Then, G to the power of a real number is used to represent the image sequence and also for pose estimation Two estimation methods are proposed and evaluated with real image sequences from the COIL-20, COIL-100, and ALOI datasets, and also compared to the Parametric Eigenspace method Additionally, we discuss the relationship of the proposed approach to the pixel-wise Discrete Fourier Transform (DFT) and to linear regression, and also outline several extensions.

3D head model generation using full-face head shape measurement system

Systems and Computers in Japan 38 ( 13 ) 82 - 91 2007.11

　View Summary

Recently, the application of human facial shapes has been attracting interest in such fields as authentication, amusement, and medical care. However, the systems now used in practice heavily burden the person undergoing measurement, because a long time is required for measurement and the user must maintain his or her facial expression. The paper considers the measurement of the human face and proposes a fast method for head shape measurement in which the number of projected patterns is decreased by utilizing the continuity of the facial shape and the uniformity of its reflectivity. Specifically, based on the assumption of continuity of the facial shape, the pattern projection of the upper bits is omitted in the spatial coding, and the spatial code is restored by utilizing the continuity of the facial shape. By applying this method, shape measurement with 8-bit spatial resolution in the depth direction is achieved by five pattern light projection operations. Based on the fact that the reflectivity of the face is almost uniform, binarization is performed without complementary pattern projection, by using average image comparison and local threshold setting. With these measures, the head model can be acquired by the proposed method in 14 pattern imaging operations, compared with 36 pattern imaging operations required in the conventional measurement system based on spatial coding using complementary pattern light projection. © 2007 Wiley Periodicals, Inc.

　View Summary

In this paper the authors propose a method to use interpolation to eliminate characters in only one image with telops or other text through an image interpolation method that uses the eigenspace method. Background scenes and other images have a fractal character, and often the self-correlation in the image can be assumed to be high. The authors focus on this point and represent rules for describing the image based on an eigenspace consisting of only one image that has defects. The eigenspace generated in this manner reflects the features of the image, and by using this eigenspace, image interpolation can be achieved. Although this interpolation method does not restore the original image, the authors confirmed through experimental results that it can provide interpolation without a feeling of oddness for images which have a high level of self-correlation. © 2006 Wiley Periodicals, Inc.

　View Summary

The defect inspection that used image sensing such as automated pattern inspection is a useful solution to automatize the visual check, not limit to factory automation field. Mostly such defect inspection is using the models of defect that described by primitive features. This paper proposes a new defect detection method that is the non-model based approach. In this approach, the method extracts the image description rule from local regions. It is useful for the defect inspection problems that cannot prepare a defect model such as scratch or superimpose detection, texture image analysis, etc. In the experiment, I tiled the defect detection to the landscape picture which several types of superimpose were added. From these results, it was confirmed that the proposed method has high ability to detect the defected regions independently with the texture type. Furthermore, I attempted the application to a scene image. Therefrom, the possibility to apply the figure-ground separation of the image understanding basic problem was confirmed.

近年,認証やアミューズメント,医療分野などにおいて人物の顔画像のみならず顔形状の応用が注目されている.しかし,現在実用化されているシステムでは計測時間が長く,表情を意識的に固定する必要があるなど被計測者に対する負担が大きい.そこで,本論文では人間の顔計測を前提とし,顔形状の連続性や反射率の一様性から投影パターン数を削減することで高速な頭部形状計測手法を提案する.具体的には,顔形状の連続性の仮定より空間コード化法における上位ビットのパターン投影を省略し,顔形状の連続性から空間コードの復元を行う.この手法を用いることにより奥行方向の空間分解能が8 bitの形状計測を5回のパターン光投影より実現した.また,顔の反射率がほぼ一様であることから,平均画像比較法と局所的にしきい値を決定することにより相補パターン投影法を用いない2値化を実現した.以上より,従来の相補パターン光投影を用いた空間コード化法を用いた計測システムでは36回のパターン撮影が必要であったのに対し,本システムでは14回のパターン撮影で頭部モデルの取得が可能となった.

Consequently, we developed a next-generation document imaging device (Eye Scanner) which can image characters or photographs on a curved sheet from an arbitrary viewpoint, without contact and without distortion, by utilizing shape information. This paper gives an outline of the Eye Scanner device and proposes a method of eliminating texture distortion of a curved object imaged from an arbitrary viewpoint. A divided imaging and connection method by using a pan-tilt stage is presented. © 2004 Wiley Periodicals, Inc.

Image interpolation by high dimensional projection based on subspace method

T Amano

PROCEEDINGS OF THE 17TH INTERNATIONAL CONFERENCE ON PATTERN RECOGNITION, VOL 4 ( IEEE COMPUTER SOC ) 665 - 668 2004 [Refereed]

　View Summary

This paper presents a new image interpolation technique for image cracking such as telop character occlusion or picture deterioration. The landscape picture and texture pattern or other natural scenes contain the behavior of the autocorrelation pattern, and a method of image interpolation based on the autocorrelation pattern has been established. This method extracts many local regions from a piece of image and generates a subspace by the image vectors. The subspace limits the freedom of the image description at the local region by the hyperplane restriction in the image vector space. This paper explains for an image interpolation method based on eigen-space and explains the expansion using kernel non-linear projection.

近年カーネル主成分分析やSupport Vector Machineなどで代表される非線形部分空間法が注目を浴びている.これらの非線形部分空間法は特徴空間上のクラス境界が非線形関数によって表現できる問題について,適切なカーネル関数を用いることによりその分布に適した非線形の部分空間を生成することが可能であり,線形の部分空間よりも低い次元の部分空間でより精度の高いパターン認識を可能とする有効な手法である.本論文ではこの非線形部分空間射影の手法を筆者らが先に提案した固有ベクトル列により張られる超平面を知識とする欠落データの補間手法(BPLP法)に組み込むことにより,高次元の非線形射影を求めるカーネルBPLP法(kBPLP法)を提案する.また,テロップ文字などにより情報の欠落が生じた画像の補間問題にkBPLP法を適用し,BPLP法や他手法の補間結果との比較により本手法の有効性を評価する.

Up to now a copying machine requires setting the document to the copy glass of the designated position. In addition to that, the copying machine cannot copy the non-flat shape document without distortion. So, we propose a next generation's document reader "Eye Scanner". The Eye Scanner is composed of the range finder, digital camera and pan-tilt stage system. Due to these devices, the Eye Scanner is able to read the document by the free viewpoint and able to generate the image which is not distorted by the geometric conversion. In this paper, we explain about the detail of the system. At the experiment, we show some result of distortion correction and show the result of image merging at divide capture.

Eigenspace approach for object recognition and its pose detection

Toshiyuki Amano, Akashi Yamaguchi, Seiji Inokuchi

Systems and Computers in Japan 31 ( 11 ) 60 - 69 2000.10

　View Summary

Range images are useful data in object recognition and pose detection. Most object recognition and pose detection techniques utilizing range images compare the geometrical features extracted from the range images to geometrical models. However, because of the difficulty in stabilizing feature extraction and the explosion in the matching combinations as the geometric models become complex, the subjects were restricted to geometrically simple objects. Previously, we proposed adapting eigenspace matching to object recognition and pose detection using range images and described eigenspace matching for range images with missing pixels. Since range images directly represent shape, by preparing the shape model of the target recognition object beforehand, virtual range images can be generated on a computer, and the eigenspace can be generated. If multiple range images are combined as the shape model, the cost of acquiring the learning samples, which is a problem in eigenspace matching, can be greatly reduced. In this paper, we focus on reducing the costs of acquiring learning samples for eigenspace matching and apply the eigenspace obtained by virtual learning to an actual range finder to demonstrate its effectiveness.

　View Summary

© 2019 SPIE. Reflected illumination from a surface provides a variety of information about material perception. A precisely designed illumination projection with a video projector changes the reflected illumination, and it manipulates our material perception, apart from the apparent texture and color. In this paper, several works on perceptual material appearance manipulation that employ projector-camera systems are presented. Psychophysics-based image processing algorithms that utilize co-axial optical configuration facilitate successive manipulation. In our latest work, viewing-direction-dependent appearance manipulation using light-field projection on an anisotropic reflection surface is proposed for advanced material perception manipulation.

This paper proposes a principle statistical approach for GP (ground plane) detection by using depth camera. Current GP detection algorithms have focused on calculating the minimum distance to estimating the ground plane, while less of them have considered the probability distribution and the angle of the camera to improve the performance.In this paper, we employ the KDE (Kernel Density Estimator) to obtain the probability density of the height distribution, with which the GP can be estimated. By using the estimated GP we calculate the angle of camera, and then feedback it to update GP until a certain condition has been reached. We evaluate our algorithm named as AGP-CIC(Angle-GP cross iterative convergence) on many challenging scenes and compare it with other distance-based algorithms.

　View Summary

The Spatial Augmented Reality using the projector and camera system enables the geometrical compensation of the projection image based on the pixel correspondence (pixel map) between a capture image and a projection image obtained by the calibration. However, an artifact pattern is generated by a projection image because of a disparity between the pixel map and a physical projection when the projection is changed. In this paper, we propose the geometrical calibration method that update the pixel map adaptively. The idea is it uses the artifact pattern, and calculates the optical flow between a projection image and a capture image based on epipolar constraint.

The spatial augmented reality technique that consists of a projector and a camera enables the appearance manipulation of real world by the illumination projection. Today, since the projector keeps getting smaller, the SAR made composed by mobile devices became a realistic story. However, it is difficult to calibrate an optical response beforehand because the use in various illumination environment is supposed for the mobile SAR system. In this research, we propose the method that achieves an invariant appearance manipulation for the various ambient lighting by the accurate reflectance estimation using DLP projector.

We report a result of an experimental study on properties of pose representations for 3DOF linear pose estimations with 100 CG objects. We use linear regression as a pose estimation method. First, we explain a method of linear pose estimation and two properties of pose representations. Next, we use four pose representations (rotation matrix, ZYX Euler angle, exponential map, and quaternions), for pose estimation experiments, and compare estimation errors. We show that estimation error of rotation matrix is significantly smaller than other representations by using pairwise t-test.

　View Summary

In the image parameter estimation by the linear regression, it has very high degrees of freedom for the decision of regression coefficients, because the dimension of image vector is huge high. In this paper, we propose a sequential regression coefficient calculation algorithm, and we realize its calculation for dense samples with reasonable computational cost. Moreover, we apply this method to the pose estimation of the 3-D object, and we discuss about limit of parameter estimation ability by the linear regression with the coil-20 image library.

We demonstrate interpolation of the image sequence by rotation in the subspace, and discuss the ability of the proposed linear map onto the subspace.
Prediction of a path of pedestrian using combination of Eigenspace and null space

This paper proposes a method for Eigenspace-based prediction of a person's path in future with current path. This method uses projection and back projection of the current path onto Eigenspace. However, the prediction does not take the nature of a path of pedestrian and results in non-smooth path. The proposed method modify the prediction by using null vectors in the orthocomplement of the learned Eigenspace and adding linear combinations of the null vectors to the prediction so that the path becomes smooth. Coe?cients of the linear combinations are computed by decent gradient method. Some experimental results on actual pathes are shown.

This paper proposes a new method for estimation of pose of a 3D object rotating about an axis by using a subspace with block diagonalization of a cyclic transient matrix of the image sequence of the object. The proposed method searches the pose parameter with the distance between an image and the standard image multiplied with a block diagonal matrix in the subspace. Alternative method that directly estimates the pose parameter as an angle subtended by two vectors in two-dimensional subspace. Experimental results with a real image sequence demon-strate that the maximum estimation error is about 4[deg], and 1.23[deg] in average, which show the effectiveness of the proposed method.

　View Summary

In this paper, a method to recognize 3-D object in parallel is proposed as the improvement of the EbC method that is a parameter estimation solution such as posture of the 3-D objects. The proposed method can realize high-speed object recognition with maintaining small learning data to compares an unknown object image with two image vectors, called EbC image pairs, provided every object by learning. In other words, the proposed method uses the property that projection points of target images are corresponding to circular edge of a plane that generated by EbC image Pair. In recognition experiment, recognition performance of proposed method was verified using COIL-20. Moreover, the effectiveness of the proposal method was considered from comparison with the recognition result in the CLAFIC method that is the method known well conventionally.

IEICE technical report ( The Institute of Electronics, Information and Communication Engineers ) 106 ( 605 ) 25 - 30 2007.03

　View Summary

This paper proposes a method for Eigenspace-based prediction of a person's path in future with current path. This method uses BPLP proposed by Amano et. al.: projection and backprojection of the current path onto Eigenspace. However, the prediction does not take the nature of a path of pedestrian and results in non-smooth path. The proposed method modify the prediction by using null vectors in the orthocomplement of the learned Eigenspace and adding linear combinations of the null vectors to the prediction so that the path becomes smooth. Coefficients of the linear combinations are computed by decent gradient method. Some experimental results on actual pathes are shown.

MIRU 2006 画像の認識・理解シンポジウム論文集 ( 電子情報通信学会 ) 460 - 465 2006.07

　View Summary

In this paper, we propose a method called EbC, Estimation-by-Completion, a high speed estimation of pose parameters of a three-dimensional object in an image. For appearance-based pose estimation, EbC method introduces the concept of information track that represents the parameters embedded into image samples. The pose parameters are estimated by the completion of the information track with BPLP method, an image interpolation technique with eigenspace learning. EbC integrates the completion of the information track and the estimation of the parameters into pairs of two images, called EbC image pairs, and performs quickly the estimation by few inner products of images. Experimental results for pose estimation results of three degree of freedoms, rotation about vertical axis and horizontal and vertical translations, show the accuracy, and calculation cost of EbC method is described.

　View Summary

In these years, nonlinear subspace method, kPCA and Support Vector Machine have attracted a great deal of interest. These nonlinear subspace methods can generate the nonlinear subspace for pattern distribution by using appropriate kernel function about the problem that class boundary on feature space has expressed by a hypersurface. Therefore these methods are able to high accurate pattern recognition. In this paper, we propose an image interpolation method that based on above nonlinear subspace methods. Concretely we applied the nonlinear subspace to BPLP method based on linear subspace and got the kernel BPLP method that is a high dimensional nonlinear projection.

Technical report of IEICE. PRMU ( The Institute of Electronics, Information and Communication Engineers ) 101 ( 421 ) 21 - 26 2001.11

　View Summary

This paper presents a technique of analyzing the degree of movement in facial parts during expressions using range and intensity information. Pre-determined facial actions are measured by a rangefinder system called 'Cubicfacer' which produces dense 3D and color texture images of a measuring subject. A topological face mesh is constructed and adapted to the measured range data using the information in the corresponding color image. The mesh adaptation process is done iteratively by approximating a polynomial function with the least squares estimation. Patch variances of sub-meshes are then computed to analyze the movements of different facial parts. The experiment is done for apparent normal and disordered human subjects to determine the differences in facial movements.
Influence of Dummy Binocular Disparities and Monocular Clues on the Depth Perception

Technical report of IEICE. PRMU ( The Institute of Electronics, Information and Communication Engineers ) 101 ( 421 ) 127 - 132 2001.11

　View Summary

The phenomenon in which depth feeling increases is known for many years by giving dummy binocular disparities to a single picture, and getting rid of the vergence. Although the reason is not solved yet, if solved, it is clear to take a big step toward realization of stereoscopic vision from a single picture. Then, towards realization of stereoscopic vision by the single picture, the influence on the depth perception which dummy binocular disparities and monocular clues do was investigated quantitatively. From the result, depending on the intensity of monocular clues, it became clear to enable depth perception of the same grade as the case where a stereo picture is used also by use of the picture which added dummy binocular disparities.

It is difficult to decide what kind of and how many visual information from figure characteristics for recognition. However, if a quantity of all visual information can be decided, we can decide kind and amount of visual information, and have a clue to make it clarify the mechanism of brain for visual information process. In this paper, we show the possibility of measurement of the Visual Complexity that is defined as a quantity of all figure characteristics in the object, which are source of visual information, with measurement of the Effective Visual Field for recognizing character, and Eyesight Distribution on Retina.

　View Summary

Range-image is one of a useful data for the recognition and localization of freeform 3-D object. Most recognition and pose-detection methods from range-image have to use a feature extraction, but it is necessary a simply model and difficult to extract features. Besides central to this issue is the problem of feature matching on the object and range-image. So we proposed use of appearance-matching technique on the range-image. To use range image for the appearance-matching has one more advantage. Range-image expresses a geometrical object information. So, it is easy to make range-image from polygon data to using camera-parameter, and large numbers of sample images from reality measurement are not necessary. In the fact large number of sample is the key to use appearance-matching. In this paper we propose a methodology for the recognition and pose-detection of freeform 3-D object by appearance-matching on the range-image.

An application of the pose detection using range images usually uses characteristic matching of the geometrical model but this method has two problems: selecting characteristics from range images is difficult
and it is difficult to make a geometrical model for a complicated shape. Previously a parametric eigen-space method was proposed for pose detection. This method makes object recognition and pose detection possible, but this parametric eigen-space method has a problem that intensity-images depend on a variety of light conditions therefore learning images must include variation of light conditions. © 1996 IEEE.

　View Summary

我々の開発したシリコンレンジファインダ(以下,SRF)はビデオカメラ以上の速度で距離画像を計測することの出来るデバイスであり,ビジュアルフィードバック等の動距離画像処理分野での応用が期待されている.このような3次元デバイスを実応用するためには柔軟性の高いキャリブレーション手法が必要であり,これまでにシステムパラメータによる方法が利用されてきた.しかしSRFは専用チップによりレーザ光を受光するため,シーンの明暗を計測することが出来ない.そのためプリズムを用いて同一レンズを通した画像を撮影することでカメラ系のキャリブレーション問題を解決した.また,プロジェクタ系に回転ミラーを用いているために,透視変換に基づく方法であるシステムパラメータ法を用いることが出来ない.そこで仮想スクリーンという概念を導入し,ミラーの回転角をプロジェクタ座標に補正することでシステムパラメータ表現を実現した.SRFをシステムパラメータによりキャリブレーションすることにより,各種応用分野への柔軟な対応が可能となった.

　View Summary

本稿では，プロジェクタ-カメラシステムにより，動的シーンにおいて鏡面反射成分・拡散反射成分・大域成分を分離する手法を提案する．静的シーンでは，高周波パターン光の投影による直接・大域成分の分離，および，偏光を用いた鏡面反射成分・拡散反射成分の分離が可能である．ところが，これらを動的シーンに適用するには，照明の空間的パターンと偏光状態の両方を高速に切り替える必要がある．そこで提案手法では，DLPプロジェクタのカラーホイールを直線偏光板で置き換えた偏光プロジェクタと高速度カメラを用いて撮影した画像に基づいて，動的シーンにおける成分分離を実現する．試作機を用いた実験を行い，提案手法の有効性を示す.

　View Summary

© 2016 IEEE. Appearance of objects change from their original colors according to a lighting condition. Nowadays, a projector-camera system can act a tool to control colors or textures of objects in each small area divided in pixel level by light projection onto their physical surfaces. Conventional system can change the appearance in realtime under constant environmental lights. However, the change of environmental lights also influence the appearance. Therefore, we propose an advanced appearance control method considering the change of the environmental lights. In particular, we use a projector-camera system consisting of two cameras and one 3D projector. In addition, we apply liquid crystal shutter filters in order to estimate reflectances and variations of environmental lights separately simultaneously in real-time. In this paper, we show our theory for the estimation and results under different conditions of environmental lights.

Intention Augmentation in Calligraphy Work with Light Projection

映像情報メディア学会技術報告 2016.03.02

　View Summary

Calligraphy work shows various expressions by using shades of the ink and textures of the papers, although the appearance seems to be just black and white at a glance. This appearance acts as the only interface through which calligraphers can express their intention to appreciators. At exhibition places, such as museums or galleries, lighting is an important element to prepare the best appearance for displaying these art works. In this study, we apply a projector-camera system as novel lighting for exhibitions instead of conventional lighting. The camera captures delicate expressions of the calligraphy work and the light projection enhances the expressions. First, we extracted kansei words from calligraphy evaluations by professionals, then we made a positioning map. Second, we conducted experiments to find projection modes corresponding to parts of the map using real calligraphy works. Finally, we discussed "Intention Augmentation" exemplified by our novel lighting for exhibitions.

　View Summary

This paper proposes a principle statistical approach for GP (ground plane) detection by using depth camera. Current GP detection algorithms have focused on calculating the minimum distance to estimating the ground plane, while less of them have considered the probability distribution and the angle of the camera to improve the performance.In this paper, we employ the KDE (Kernel Density Estimator) to obtain the probability density of the height distribution, with which the GP can be estimated. By using the estimated GP we calculate the angle of camera, and then feedback it to update GP until a certain condition has been reached. We evaluate our algorithm named as AGP-CIC(Angle-GP cross iterative convergence) on many challenging scenes and compare it with other distance-based algorithms.

　View Summary

The spatial augmented reality technique that consists of a projector and a camera enables the appearance manipulation of real world by the illumination projection. Today, since the projector keeps getting smaller, the SAR made composed by mobile devices became a realistic story. However, it is difficult to calibrate an optical response beforehand because the use in various illumination environment is supposed for the mobile SAR system. In this research, we propose the method that achieves an invariant appearance manipulation for the various ambient lighting by the accurate reflectance estimation using DLP projector.
Adaptive geometrical compensation of projection image by update the pixel map

笠谷昇平, 天野敏之, 大槻正樹

情報処理学会研究報告(Web) 2014.02.24

　View Summary

The Spatial Augmented Reality using the projector and camera system enables the geometrical compensation of the projection image based on the pixel correspondence (pixel map) between a capture image and a projection image obtained by the calibration. However, an artifact pattern is generated by a projection image because of a disparity between the pixel map and a physical projection when the projection is changed. In this paper, we propose the geometrical calibration method that update the pixel map adaptively. The idea is it uses the artifact pattern, and calculates the optical flow between a projection image and a capture image based on epipolar constraint.

In this paper a novel image capturing method for a solution of shading problem in computer vision is proposed. In the experiments, we performed the evaluation about the conditions of environment lighting and additional lighting and proposed controlled lighting method. Image-processing of self quotient image algorithm, histogram equalization, and luminance equalization were used for pre-processing to remove shading from a captured image for the comparative evaluation. Through the evaluation of robustness assumed appearance based method, the proposed method showed most stable results. In addition to this, the capability of the high dynamic range image reconstruction with approximation by using of projector camera system has been shown.

Augmented Reality (AR) is a display technology which can overlay virtual objects or information on top of the real world. One effective application of such technology is user 's activities support such as machine operation, maintenance and assembly. In addition, AR can integrate real and virtual world seamlessly even if the information is not associated with a specific location in the real world. Since this type of AR information display can also be achieved using other methods therefore it is necessary to compare these methods and evaluate their effectiveness. In this research, we implemented an AR-Dictionary system as an example of such information display. We also aim to evaluate its effectiveness by comparing it to different types of information display methods.

In this paper, we propose a method to generate fluid surface including turbulent flow by dividing fluid particles into sub-particles and updating positions and velocity field that usual particle method can not capture. We implement this method and verify it.

Proceedings of the 7th IASTED International Conference on Signal Processing, Pattern Recognition and Applications, SPPRA 2010 2010.07.20

　View Summary

In this paper, we show that a more accurate estimation of a 3 × 3 rotation matrix R can be achieved by appropriately decomposing higher-order rotation matrices: R2, R3, and so on. First we discuss an angle estimation of a 2 × 2 rotation matrix inspired by the Electronic Distance Measurement. Then we reformulate the problem for a 3 x 3 rotation matrix: if noise-contaminated measurement matrices R, R2,⋯, Rn are given, find an appropriate rotation matrix R. In the proposed method, the given measurement matrices are first transformed to rotation matrices by using the polar decomposition. Then the rotation angles are obtained by using an eigen decomposition of the rotation matrices. Finally, the ambiguity of the obtained rotation angle is removed. Experimental results show that the use of Rn results in more accurate estimates than when R itself is used.

　View Summary

In this paper, we describe a high speed and multi degree of freedoms (DOFs) pose estimation method for a 3-D object that called Estimation-by-Completion (EbC) method. The most of employed processes are described with linear calculation, thus, whole procedure for each parameter estimation is expressed by a pair inner production, and it used only an arctangent calculation at the final part of the estimation. The accuracy evaluation by 3DOFs pose estimation that includes rotation around the object's vertical and horizontal translations is shown in experiment. We also describe its calculation cost in discussions.
Linear 3-D object pose estimation with dense sample images -Discussions about limitation of parameter estimation ability by the linear regressions

Proceedings of the 11th IAPR Conference on Machine Vision Applications, MVA 2009 2009.12.01

　View Summary

In the image parameter estimation by the linear regression, it has very high degrees of freedom for the decision of regression coefficients, because the dimension of image vector is huge high. In this paper, we discuss its potential by the learning of the dense samples. For the learning process, we employed a sequential regression coefficient calculation algorithm and realize its calculation for dense samples with reasonable computational cost. Through the experimental result, we discuss about the limitation of parameter estimation ability by the linear regression.

We report a result of an experimental study on properties of pose representations for 3DOF linear pose estimations with 100 CG objects. We use linear regression as a pose estimation method. First, we explain a method of linear pose estimation and two properties of pose representations. Next, we use four pose representations (rotation matrix, ZYX Euler angle, exponential map, and quaternions), for pose estimation experiments, and compare estimation errors. We show that estimation error of rotation matrix is significantly smaller than other representations by using pairwise t-test.

情報処理学会研究報告 2008.01.17

　View Summary

Virtual pop-up books are systems which can overlay a captured image with 3D CG objects based on augmented reality technology. 3D geometrical consistency in the composite image can be kept by estimating the relative pose of the camera from the physical book. We have been studying about this pose estimation method using feature tracking based on template matching. Since multi-core CPUs have been spread in recent years, it can be easily achieved to improve the performance speed by parallel processing on a standard PC environment. We modified our tracking codes for parallel processing by multi-core CPUs and improved the performance speed and robustness of the tracking.

電子情報通信学会技術研究報告 2007.10.18

　View Summary

In this paper, a new approach of defect detection from complex texture patterns that have structural regularity for automated visual inspection is proposed. The approach uses correlation based defect detection, and any kind of model of defect feature is unnecessary. Additionally, proposed method applies k-means clustering to the samples acquired by pixel-by-pixel movement of sampling window, and achieves a very sensitive defect detection. In the experiment, the effectiveness is shown through the experiment by the complex texture patterns that have structural regularity.

Prediction of a path of pedestrian using combination of Eigenspace and null space

MIRU 2007 画像の認識・理解シンポジウム論文集 2007.07

　View Summary

This paper proposes a method for Eigenspace-based prediction of a person's path in future with current path. This method uses projection and back projection of the current path onto Eigenspace. However, the prediction does not take the nature of a path of pedestrian and results in non-smooth path. The proposed method modify the prediction by using null vectors in the orthocomplement of the learned Eigenspace and adding linear combinations of the null vectors to the prediction so that the path becomes smooth. Coe?cients of the linear combinations are computed by decent gradient method. Some experimental results on actual pathes are shown.

　View Summary

This paper proposes a new method for estimation of pose of a 3D object rotating about an axis by using a subspace with block diagonalization of a cyclic transient matrix of the image sequence of the object. The proposed method searches the pose parameter with the distance between an image and the standard image multiplied with a block diagonal matrix in the subspace. Alternative method that directly estimates the pose parameter as an angle subtended by two vectors in two-dimensional subspace. Experimental results with a real image sequence demon-strate that the maximum estimation error is about 4[deg], and 1.23[deg] in average, which show the effectiveness of the proposed method.

KIMURA Masayuki, AMANO Toshiyuki, TAMAKI Toru, UMEZAKI Taizo

IEICE technical report 2007.05.17

　View Summary

In this paper, a method to recognize 3-D object in parallel is proposed as the improvement of the EbC method that is a parameter estimation solution such as posture of the 3-D objects. The proposed method can realize high-speed object recognition with maintaining small learning data to compares an unknown object image with two image vectors, called EbC image pairs, provided every object by learning. In other words, the proposed method uses the property that projection points of target images are corresponding to circular edge of a plane that generated by EbC image Pair. In recognition experiment, recognition performance of proposed method was verified using COIL-20. Moreover, the effectiveness of the proposal method was considered from comparison with the recognition result in the CLAFIC method that is the method known well conventionally.

　View Summary

This paper proposes a method for Eigenspace-based prediction of a person's path in future with current path. This method uses BPLP proposed by Amano et. al.: projection and backprojection of the current path onto Eigenspace. However, the prediction does not take the nature of a path of pedestrian and results in non-smooth path. The proposed method modify the prediction by using null vectors in the orthocomplement of the learned Eigenspace and adding linear combinations of the null vectors to the prediction so that the path becomes smooth. Coefficients of the linear combinations are computed by decent gradient method. Some experimental results on actual pathes are shown.

Estimation-by-Completion : A linear method for pose estimation of 3D object

天野敏之, 玉木徹

MIRU 2006 画像の認識・理解シンポジウム論文集 2006.07

　View Summary

In this paper, we propose a method called EbC, Estimation-by-Completion, a high speed estimation of pose parameters of a three-dimensional object in an image. For appearance-based pose estimation, EbC method introduces the concept of information track that represents the parameters embedded into image samples. The pose parameters are estimated by the completion of the information track with BPLP method, an image interpolation technique with eigenspace learning. EbC integrates the completion of the information track and the estimation of the parameters into pairs of two images, called EbC image pairs, and performs quickly the estimation by few inner products of images. Experimental results for pose estimation results of three degree of freedoms, rotation about vertical axis and horizontal and vertical translations, show the accuracy, and calculation cost of EbC method is described.

Influence of Dummy Binocular Disparities and Monocular Clues on the Depth Perception

ARAKAWA Naofumi, ISHIKAWA Hiroyo, AMANO Toshiyuki, SATO Yukio

Technical report of IEICE. Multimedia and virtual environment 2002.11.08

　View Summary

The phenomenon in which depth feeling increases is known for many years by giving dummy binocular disparities to a single picture, and getting rid of the vergence. Although the reason is not solved yet, if solved, it is clear to take a big step toward realization of stereoscopic vision from a single picture. Then, towards realization of stereoscopic vision by the single picture, the influence on the depth perception which dummy binocular disparities and monocular clues do was investigated quantitatively. From the result, depending on the intensity of monocular clues, it became clear to enable depth perception of the same grade as the case where a stereo picture is used also by use of the picture which added dummy binocular disparities.
Facial Movement Analysis with Iterative Mesh Adaptation

GUNARATNE Pujitha, AMANO Toshiyuki, SATO Yukio

Technical report of IEICE. Multimedia and virtual environment 2002.11.08

　View Summary

This paper presents a technique of analyzing the degree of movement in facial parts during expressions using range and intensity information. Pre-determined facial actions are measured by a rangefinder system called 'Cubicfacer' which produces dense 3D and color texture images of a measuring subject. A topological face mesh is constructed and adapted to the measured range data using the information in the corresponding color image. The mesh adaptation process is done iteratively by approximating a polynomial function with the least squares estimation. Patch variances of sub-meshes are then computed to analyze the movements of different facial parts. The experiment is done for apparent normal and disordered human subjects to determine the differences in facial movements.

Due to these devices, the Eye Scanner is able to read the document by the free viewpoint and able to generate the image which is not distorted by the geometric conversion. In this paper, we explain about the detail of the system. At the experiment, we show some result of distortion correction and show the result of image merging at divide capture.

Although the reason is not solved yet, if solved, it is clear to take a big step toward realization of stereoscopic vision from a single picture. Then, towards realization of stereoscopic vision by the single picture, the influence on the depth perception which dummy binocular disparities and monocular clues do was investigated quantitatively. From the result, depending on the intensity of monocular clues, it became clear to enable depth perception of the same grade as the case where a stereo picture is used also by use of the picture which added dummy binocular disparities.

　View Summary

It is difficult to decide what kind of and how many visual information from figure characteristics for recognition. However, if a quantity of all visual information can be decided, we can decide kind and amount of visual information, and have a clue to make it clarify the mechanism of brain for visual information process. In this paper, we show the possibility of measurement of the Visual Complexity that is defined as a quantity of all figure characteristics in the object, which are source of visual information, with measurement of the Effective Visual Field for recognizing character, and Eyesight Distribution on Retina.

Proceedings - International Conference on Pattern Recognition 1996.01.01

　View Summary

An application of the pose detection using range images usually uses characteristic matching of the geometrical model but this method has two problems: selecting characteristics from range images is difficult; and it is difficult to make a geometrical model for a complicated shape. Previously a parametric eigen-space method was proposed for pose detection. This method makes object recognition and pose detection possible, but this parametric eigen-space method has a problem that intensity-images depend on a variety of light conditions therefore learning images must include variation of light conditions. © 1996 IEEE.

「見かけ」を変える技術．イノベーションジャパン２０１３からの紹介です。プロジェクターマッピングなど静止した対象物に映像を投影する技術が一般化する中で、これは世界初というリアルタイムで移動する立体物を把握し、その見かけを変える事が出来る技術です。これは拡張現実感の技術の一つですが、リアルタイムでの処理は舞台などエンターテイメントの世界での応用はもちろん、一般の人の見る力を高めることで、生活の質を高める応用が楽しみです。
