Overlapped patch elimination algorithm for deformable mesh video coding

Updating mesh nodal points is one of the major tasks in deformable mesh video coding. Owing to object movement and inexact motion estimation, nodal point tracking often results in overlapped patches. A noniterative nodal point processing algorithm is proposed to solve this problem. Simulation results indicate that with this overlapped patch elimination algorithm, the updated mesh can maintain a rather uniform distribution and the moving object can be traced quite well
