摘要 由于解码器后处理错误隐藏技术主要在解码器端完成,不会在码流信息中加入冗余信息,所以解码器后处理错误隐藏技术在实践中得到广泛应用。目前解码器后处理错误隐藏方面已经提出了多种有效的方法,在对比现有的几种时空域错误隐藏的算法的基础上提出了针对视频流中I帧,P帧图像中不同的出错区域采用自适应的时空域错误隐藏算法来恢复原图像,模拟测试表明,该算法能够有效提高视频质量。 As decoder post-processing error concealment technology mainly in the decoder completed,the stream of information will not add redundant information,so decoder post-processing error concealment techniques in practice is widely used.After dealing with the current decoder error has been hidden by a variety of effective methods,the paper in contrast,the existing spatial and temporal errors on the basis of the algorithm proposed for video streaming of I/P frames in different districts of error adaptive spatial and temporal error concealment algorithm to restore the original image,simulation tests show that the algorithm can effectively improve the video quality.
