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