| Abstract |
In this paper, we propose a hierarchical triangular mesh generation method based on the motion information and a fast node convergence method. From the variance of Image difference, we decide the region that subdivision is required and perform the adequate triangulation method that is possible to yield a successive hierarchical triangulation. For fast node convergence, in initial search, we use the refinement method that separate the backgroung and object region and maintain the mesh connection by using the bilinear interpolation. The simulation result demonstrate that proposed triangulation method have better performance in PSNR than the conventional BMA or other mesh based method and refinement method is appropriate for the case of the mesh size is small. |
