This paper introduces a new algorithm for tracking nonrigid motion in image sequences. Non-rigid motions are modeled as the deformations of connected 2D membrane patches. Local smoothness constraints for each patch are the low-frequency vibration modes obtained from modal analysis. Hinges are imposed between patches to maintain the global topological structure. The resulted over-constrained linear system is solved efficiently using a least square estimator. Promising results on both natural and synthetic facial motion sequences are demonstrated in this paper.
