Abstract

In the context of block-based video coding, two error concealment algorithms are presented. The first algorithm is based on bilinear motion field interpolation (BMFI). For each pel in a damaged block, the algorithm recovers a motion vector using bilinear interpolation of neighbouring motion vectors. This vector is then used to conceal the damaged pel. A reduced complexity version of this algorithm is also presented. The second algorithm uses overlapped motion compensation to combine the first algorithm with a boundary matching error concealment algorithm. Simulation results show that at low error rates the first algorithm outperforms other concealment techniques, but its performance starts to deteriorate with increasing error rate. The second algorithm, however, maintains a superior performance regardless of the error rate. Simulation results within an H.263 codec are also presented.
