  • When bit errors occur during transmission and cannot be corrected by an error correction scheme, error concealment is needed to mask damaged image at receiver. In this paper, a spatio-temporal error concealment algorithm based on fuzzy classify and mesh warping method is presented. The algorithm include two steps: First , the error blocks which are in the situation of pure translation are reconstructed. If the complicated motion such as rotation and zoom in or out is detected , the internal texture of each block is warped by a mesh-based affine transform, in order to comply with nontranslation. Experimental results show that the PSNR has been improved 1.5dB than the BMA-MBW, and 3.5dB than the BMA.
