摘要：
Error concealment is an attractive approach to combat channel errors for video transmission. A motion vector recovery algorithm for temporal error concealment is proposed. The motion vectors field is modeled as Gauss-Markov Random Field (GMRF) and the motion vectors of the damaged image macroblocks can be recovered adaptively by Maximum a Posteriori (MAP). Simulation results show that the proposed method offers significant improvement on both objective PSNR measurement and subjective visual quality of restored video sequence.
