Weighted boundary matching error concealment for HEVC using block partition decisions

We propose a weighted boundary matching error concealment method for HEVC. It uses block partition decisions to improve a common block matching algorithm that finds blocks with the best matched boundaries from the previous frame to conceal the currently corrupted blocks. The block partition decisions from the co-located block of the corrupted one are exploited. For each partition, a summed boundary weight is computed; the one with the highest weight is chosen to be concealed next. Experimental results show the proposed method performs better than conventional error concealment methods objectively and subjectively.
