- W2368163639 abstract "In order to overcome the problem of the inaccuracy of the boundary matching algorithm to lead to leakage selection of the optimal motion vector,and the effect declining of the error concealment,this paper proposed a new temporal error concealment algorithm based on extrapolation motion vectors set.Firstly,according to the temporal-spatial correlation of the motion vectors,this paper adaptively constructed a limited candidate motion vector set from neighboring macroblocks motion vectors and their extrapolation motion vectors.Secondly,it used the boundary matching algorithm to select the optimal motion vector to conceal the error from the candidate motion vectors set.Lastly,the paper realized the algorithm based on H.264/AVC JM12.2.The simulation results show that the proposed algorithm can effectively reduce the leakage selection of the optimal motion vectors,at the same time,achieve the satisfactory error concealment effect." @default.
