| 摘 要： | H.264标准由于其编码的高效性和网络亲和性成了最新的国际视频编码标准;它引进了许多新的视频编码技术,编码效率比以往的标准提高了将近50%.标准中DCT变换之后的环路滤波技术有效地滤除了块效应使得图像质量有了很大程度的提高,并且在提高峰值信噪比和降低比特率方面起着重要作用.本文详细了介绍环路滤波过程及原理算法,并通过大量序列的仿真,验证了其不可缺少的作用.

| Abstract: | H.264 becomes the newest international video coding standard because of its high coding efficiency and network friendliness.Loop filter after DCT can remove blocking artifacts,improve subjective image quality and play an important role in the peak signal to noise ratio and bit rate.This paper presents the process and the theory of loop filter algorithm,and a large number of simulation sequence has proved its important role in H.264. |
