摘要

本文提出了一种内容感知的快速块匹配运动估计算法，该算法可以在保持几乎相同的编码效率的同时降低H.264/AVC中运动估计模块的计算复杂度。在第一步中，使用块间相关性来定义有助于识别当前块的运动内容的相关系数。基于该系数，算法对不同的视频内容采用不同的搜索策略，以获得更高效的匹配。在H.264/AVC的JM12.2中实现该算法，在保持几乎相同的比特率和PSNR的情况下，减少了编码时间。

A Content Aware Fast Motion Estimation Algorithm for H.264/AVC

In this paper we propose a content aware fast block matching motion estimation algorithm that can reduce the computation complexity of motion estimation module in H.264/AVC while maintaining almost same coding efficiency. In the first step inter block correlation is used to define a correlation coefficient that helps to identify the motion content of the current block. Based on this coefficient the algorithm adopts different search strategies for different video contents to get more efficient matches. Implementation of the proposed algorithm in JM12.2 of H.264/AVC shows reduction in encoding time while maintaining almost same bit rate and PSNR.
