This paper proposes an effective algorithm for spatial error concealment with accurate edge detection and partitioning interpolation. Firstly, a new method is used for detecting possible edge pixels and their matching pixels around the lost block. Then, the true edge lines can be determined, with which the lost block is partitioned. Finally, based on the partition result, each lost pixel can be interpolated with correct reference pixels, which are in the same region with the lost pixel. Experimental results show that the proposed spatial error concealment method is obviously superior to the previous methods for different sequences by up to 4.04 dB.
