Shape Reconstruction of 3D Bilaterally Symmetric Surfaces
The paper presents a new approach for shape recovery based on integratinggeometric and photometric information. We consider 3D bilaterally symmetric objects, that is, objects which are symmetric with respect to a plane (e.g., faces), and their reconstruction from a single image. Both the viewpoint and the illumination are not necessarily frontal. Furthermore, no correspondence between symmetric points is required. The basic idea isthatan image taken froma general, nonfrontalviewpoint,under non-frontalilluminationcan be regarded as a pair of images. Each image of the pair is one half of the object, taken from differentviewingpositions and with different lightingdirections. Thus, one-image-variants of geometric stereo and of photometric stereo can be used. Unlike the separate invocation of these approaches, which require point correspondence between the two images, we showthatintegratingthephotometricand geometricinformationsuf ce toyielda dense correspondence between pairs of symmetric ...
