摘要: An algorithm using multidirectional interpolation is presented for error concealment. In the algorithm, an edge classifier analyzes values of pels in blocks surrounding missing block and determines which directions cut through block. Interpolations are performed on a local pel neighborhood along specified by classifier. Then mixing operation used to restore extracting features obtained from different directional interpolations combining them together. The method image has demonstrated very good results when sufficiently large correlated exists. This spatial can be combined with temporal provide powerful concealment technique compressed video signal transmission. >
