Abstract :
In this paper we present a novel method for tracking 3D nonrigid motion and 3D structure from a sequence of monocular, perspective images, where range data of the first frame is available. No a priori knowledge of point correspondences is assumed. A genneral approach and formulas for polynomial (second order) displacement functions are presented. An analysis of the number of equations versus the number of unknowns is given. Results for synthetic and real image sequences are presented
