Abstract

Shape recovery from a motion sequence requires the establishment of correspondence between image points. The two processes, the matching process and the shape recovery one, are traditionally viewed as independent. Yet, information obtained during the process of shape recovery can be used to guide the matching process. This paper discusses the mutual relationship between the two processes. It is shown that in images of rigid objects, objects that undergo 3D affine transformation, and rigid objects with smooth surfaces useful point correspondences along epipolar lines are useful for recovering novel views of the objects. Algorithms for recovering these correspondences using the epipolar line constraint are discussed.
