| 摘 要： | 视频压缩码流对于信道误码十分敏感,可能导致重建图像质量严重下降.误码掩盖技术利用图像在时间和空间上的相关性,可以有效地降低误码对视频图像的影响.文中提出了一种基于多方向边界匹配的时域误码掩盖算法.该算法能更精确地恢复错误宏块的运动矢量,从而获得比传统的时域掩盖算法更好的视频质量.

| Abstract: | Compressed video bitstream is sensitive to channel errors, which may degrade the reconstructed pictures severely, Error concealment is an effective approach to reducing the impact of errors by using the spatial or/and temporal correlation. This paper proposes a temporal error concealment method for video based on multi-directional boundary matching. The algorithm can restore the lost motion vectors of error block more accurately so that better video quality can be obtained. |
