Video Error Concealment Using Progressive Block Matching Algorithm with Euclidean Distance

The robustness of video transmission over wireless channel becomes more and more important especially for 4G mobile communication era. The video error concealment (EC) can recover the visual quality while the transmission error occurs. In this paper, the progressive block matching algorithm (PBMA) is proposed. The PBMA utilizes the Euclidean distance (ED) to consider the affection of corrupted-residual in block matching principle. The PBMA successively recovers the corrupted MB with minimizing the impact of corrupted-residual by ED information. At packet error rate of 20%, this work outperforms sophisticated EC algorithms by 0.13dB at least on average PSNR, as indicated from experiment result.
