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.

Technical report of IEICE. PRMU 2001.11.08

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.

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.
