摘要

当H．264编码立体视频流在Internet上传输时，由于信道错误所引起的数据丢失常常会造成整帧图像的丢失。为了恢复丢失的整帧立体视频右图像，提出了一种基于H．264的立体视频右图像整帧丢失错误隐藏算法，该算法依据立体视频编码特点进行相关性分析，首先确定丢失帧中每个宏块的预测方式，然后采用运动补偿或视差补偿对其进行恢复，进而重现丢失帧。实验结果表明，该算法能够在较低的计算复杂度下，获得较高质量的立体视频图像。

Abstract

When the compressed stereoscopic video stream generated by H. 264 coder is transmitted over the Internet

it is sensitive to packet loss. Due to the codec structure based on H. 264

a packet loss always causes the loss of an entire video frame. In such a case

a novel error concealment algorithm dealing with the loss of an entire right frame is proposed in this paper

Firstly it performs relativity analysis according to the coding scheme of stereoscopic video sequence

then obtains the prediction mode for every MB and conceals it. The experimental results show that the proposed algorithm can achieve better concealed quality with low complexity

so it is an efficient error concealment algorithm.
