摘要

压缩后的视频码流对信道错误很敏感，信道错误会严重降低重构图像的质量。在解码器上实现错误隐藏技术是减少错误影响的有效方法。他们通过使用空间或/和时间相关性来创建主观可接受质量的图像或视频，从而掩盖缺失块的影响。

An adaptive fast and efficient spatial error concealment technique for block-based video coding systems

Compressed video bitstream is sensitive to channel errors that may severely degrade the reconstructed pictures. Error concealment techniques implemented at decoders are effective approaches to reduce the impact of errors. They mask the effect of missing blocks by using the spatial or/and temporal correlation to create image or video of subjectively acceptable quality.
