Compression of 3D triangle mesh sequences

In this paper, we propose a new geometry compression algorithm for 3D mesh sequences, based on the vertex-wise motion vector (MV) prediction. In general, the MV of a vertex is highly correlated to those of adjacent vertices. To exploit the high correlation, we define a neighborhood of a vertex, and predict the MV of the vertex from those of the neighborhood. It is shown that the proposed algorithm has simpler structure than the existing segment-based algorithm. Furthermore, simulation results demonstrate that the proposed algorithm yields better compression performance than the existing algorithm.
