Video sequences error concealment based on texture detection

A new error concealment algorithm based on average motion vector (AVMV) method is proposed as a post-processing tool at the decoder side for recovering the lost blocks and their motion vectors as well incurred during the video transmission. In our proposed scheme, LOG operator is used to detect the texture of the blocks around the lost block and find the more precise estimation of the motion vectors, so as to improve the AVMV method. Simulation results show that the proposed method can recover the higher quality image in different rates of lost block, comparing to the existing traditional concealment algorithms.
