## Abstract

The paper discusses the evolution of the single object motion shape estimation (MSE) problem. Given a sequence of 2-D video images of multiple moving objects, the problem is to track the 3-D motion of the objects and reconstruct their 3-D shapes. After selection of initial feature points (FPs), the SVD may be applied to a measurement matrix formed by the FPs sequentially tracked by a video system. The distribution of singular values first reveal the information about the number of objects at hand. Then, using an algebraic-based subspace clustering method, the FPs are mapped onto their corresponding objects. Thereafter, the motion and shape are be estimated from a matrix factorization.
