本文提出了一种新的基于顶点运动矢量预测的三维网格序列几何压缩算法。通常，顶点的MV与相邻顶点的MV高度相关。为了利用高相关性，我们定义了一个顶点的邻域，并从邻域的MV预测顶点的MV。结果表明，该算法具有简单的结构比现有的基于段的算法。仿真结果表明，该算法比现有算法具有更好的压缩性能。
In this paper, we propose a new geometry compression algorithm for 3D mesh sequences, based on 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.
