Temporal error concealment algorithm for H.264/AVC based on correlation region
基于相关区域的H.264/AVC时域错误隐藏

The break of changes always exist in MVs(motion vectors) on the curves of video content split.Using interpolation formula simply to recover the lost MVs usually results in serious propagation error.The video content split prediction curve was proposed to minimize the errors based on Lagrange interpolation formula,the parameters of Lagrange interpolation formula were achieved by the use of neighbor blocks' MVs,and the lost macroblocks and the neighbor blocks were divided into several regions by the curve,the changes of motion vectors in each region were smooth.And then,the MVs of lost blocks were replaced by the average values of available motion vectors in every region.The simulation results show that the proposed algorithm can efficiently improve the visual quality of corrupted video.
