本文针对影响视频压缩效率和速度瓶颈之一的 “运动估计技术 ”展开研究。对 “运动估计 ”这一在视频通信中最重要最耗时的技术的原理和搜索算法进行了详细的介绍。同时以H.2 63视频压缩编码标准为基本框架 ,提出了实现时的一些优化措施
This article studies the “motion estimation technique” that affects one of the bottlenecks of video compression efficiency and speed. The principle and search algorithm of “motion estimation”, the most important and time-consuming technique in video communication, are introduced in detail. At the same time to H.263 video compression coding standard as the basic framework, put forward some of the optimization measures
