A temporal and spatial combined error concealment scheme for video communication
时空域相结合的视频差错掩盖方法

To overcome the shortcomings of temporal error concealment techniques in decoder that can not estimate motion vector of the loss block accurately, motion estimation in decoder and implicit motion model combined error concealment scheme is presented. First of all, we utilize the survived surrounding pixels of lost block for motion estimation, and determining the accuracy of estimates. Then we restore the missing pixels with implicit motion model making full use of the relevance of temporal and spatial domain according to the accuracy. The simulation results show that this method can improve the video image quality by 1dB than other methods.
