摘要
基于ＭＰＥＧ－２标准的错误检测和隐藏是视频领域研究的一个重点，而直流系数的铬误检测与隐藏尚属空白。本文从分析直流系数的错误特点出发，根据图像空域的相关性，首次提出了完整的ＤＣ系数错误检测和恢复算法，并通过实验对算法进行了验证，取得了满意的效果。
Error detecting and error-concealment is one emphases of video research, but detecting and recovery of IX! coefficient error don't develop. The paper begin with the error analyze, and a integrated approaches about error detecting and recovery of DC coefficient based on the relativity of image at spatial is firstly present. The proposed approach is tested by experiments and good result is gained.
