Abstract
The traditional methods of optical flow estimation have some problems, such as huge computation cost for the inverse of time-varying Hessian matrix, aperture phenomena for the points with 1D or little texture and drift phenomena with long sequences. A novel nonrigid object tracking algorithm based on inverse component uncertainty factorization subspace constraints optical flow is proposed in this paper, which resolves the above problems and achieves fast, robust and precise tracking. The idea of inverse Component is implemented in each recursive estimation procedure to make the algorithm fast. Uncertainty factorization is used to transform the optimization problem from a hyper-ellipse space to a hyper-sphere space. SVD is correspondingly performed to involve the subspace constraints. The proposed algorithm has been evaluated by both the standard test sequence and the consumer USB camera recorded sequence. The potential applications vary from articulated automation to structure from motion.
