　View Summary

This paper presents and algorithm for reconstructiong the shape of a cylindrical object from contour and shading without knowing the surface albedo of the object of the lighting conditions of the scene. Input image is segmented into spherical, cylindrical, or planar surfaces by analyzing local shading. The cylindrical surface is characterized with a direction of generationg lines determined from spatial derivatives in the image. The brightest generating line has strong constraints on both the shading analysis on the cylindrical surface and a simplification of the equation which represents the relation between the contour shape and shading. Although there remains one degree of freedom between the surface normal of the base plane and the slant angle of the generating line, we can uniquely recover the cylindrical shape from this solution. Experimental results for both synthetic and real images are shown.
