摘要

本文提出了一种高效的ＭＰＥＧ２视频编码运动估计方案．该方案利用同一宏块不同类型运动向量之间的相关性，分两级搜索．分析表明采用本文所提出的方案，与ＭＰＥＧ２测试模型５（ＴＭ５）相比，其计算量有大幅度降低，约为ＴＭ５的１７％；而且模拟实验表明该方案与ＴＭ５的ＭＳＥ、ＰＳＮＲ性能接近．由于两级搜索中都是采用全搜索策略，易于并行实现，因而本文方案为ＭＰＥＧ２视频编码运动估计的低复杂度实时实现提供了一种途径．

Abstract

In this paper

an efficient scheme of motion estimation for MPEG 2 video coding is proposed.According to the correlation of different types of motion vectors in a macroblock

the scheme is divided into two stages.Analysis shows t hat the proposed scheme can reduce about 17% of the computation employed by MPEG 2 Test Model 5（TM5）.Simulation results show that the scheme achieves nearly the same MSE and PSNR performance as TM5.Due to adopting full search strategy in the two stages

the proposed scheme can be implemented easily in parallel.It provides a way for the implement ation of MPEG 2 video coding motion estimation in real time

which has low complexity.
