一种基于AVS的错误隐藏方法

An Error Concealment Method Based On AVS

AVS标准是我国制定的拥有自主知识产权的视频压缩编码标准,对AVS标准的错误隐藏技术进行研究具有重要的意义。本文提出了一种用于AVS的错误隐藏方法,该方法对I帧和P帧采用不同的掩盖方法:基于边界的空域插值和时域的边界匹配算法,并对其纠错性能进行了实验。结果表明,重建图像的主客观质量均得到明显的改善。

AVS is China＇s Video Coding Standard, which have own intellectual property rights. The research of error concealmevtt technology based on AVS standard is of great significance, This paper presents an error concealment method that is used in AVS, the method use different ways to restore the damaged I frame or P frame： space interpolation based on the edge detection and temporal recover based on border matched. We did some experiments to test the performance of its error correction. The results showed that the reconstructed image quality has been markedly improved subjectively and objectively.
