Abstract :
Available 2-D mesh models, whether uniform or adaptive, preserve neighboring relationships between the patches (connectivity) everywhere within the frame, which is clearly not suitable across motion and occlusion boundaries. To this effect, this paper proposes an occlusion-adaptive, content-based mesh design and forward tracking algorithm, where no node points are placed within the background to be covered (BTBC), and node points along the boundary of the uncovered background (UB) are allowed to split. Furthermore, the mesh is refined within the UB region at every frame. Experimental results show successful motion compensation and tracking
