An adaptive error concealment order in H.264/AVC

摘要

Transmission of compressed video over error prone channels may result in packet losses or errors, which can significantly degrade the image quality. Aimed this problem, this paper proposed an adaptive concealment order based on well know Boundary matching algorithm [7, 8]. The concealment order is carefully chose according to a lost MB's priority, which is formulated considering 2 factors, the lost MB's MV, and its available neighborhood information. Compared with Chen's work [11], the experiments show our proposal always achieves the best performance of video recovery under different packet lost rate channel.
