Then, we propose a new triangulation procedure for mesh structure and also a new algorithm to justify connectivity of mesh structure after motion vector estimation of the mesh points. We modify the occlusion-adaptive, content-based mesh design and forward tracking algorithm used by Yucel Altunbasak for selection of points for triangular 2-D mesh design. This is achieved by allowing no node points within the background to be covered and refining the mesh structure within the model failure region at each frame. In this algorithm, connectivity of the mesh elements (patches) across covered and uncovered region boundaries are broken. To overcome this limitation, BTBC (background to be covered) detection and MF (model failure) detection algorithms are being used. However, available uniform 2-D mesh model enforces connec-tivity everywhere within a frame, which is clearly not suitable across occlusion boundaries.
