摘　　要：为了提高运动估计的搜索效率,提出了一种基于JM模型的UMHexagonS算法的改进方案。该方案减少了搜索点数,从而减小了运算量。经过实验测试,改进后的UMHexagonS算法在保证编码图像的质量基本不变的同时,能显著减少搜索时间。In order to improve the efficiency of motion estimation, this paper proposed an improvement algorithm of UMHexagonS, which is based on JM model. This improvement algorithm can reduce search points and simple the computation. The experiment show that the proposed algorithm can significantly reduce searching time with almost the same coding quality compared to the original UMHexagonS algorithm.
