摘　　要：环路滤波器是H.264视频编码标准的一个重要选项,在去除编码带来的块效应的过程中起着重要的作用。文章提出一种针对H.264/MPEG-4 AVC标准的高性能低复杂度的去块效应滤波器结构,在此基础上进行仿真实验,实验结果表明,去方块滤波在提高图像质量上效果显著。As an essential part in H. 264/AVC, the loop-filter plays an important role in removing annoying blocking distortion. An architecture of deblocking filter structure in H. 264/MPEG-4 AVC is proposed, which possesses high efficiency and low complexity. Simulation based on this architecture is carried out, and the result of which indicates that video graphic quality can be improved remarkably by removing annoying blocking distortion.
