A temporal error concealment algorithm for H.264 based on plane estimation

In this paper, we propose a new temporal error concealment algorithm for the forthcoming video coding standard H.264, which uses a first-order plane to estimate motion vector. In H.264, a 16×16 inter macroblock can be divided into variant block shape for motion prediction. The blocks within a small area are likely to move in the same direction. By using the motion vectors that next to the vertices of lost macroblock, we can constitute a first-order plane that indicate the movement tendency in this small area, and estimate the motion vector of vertices. Then the motion vectors of vertices are used to interpolate motion vector of each pixel separately. To reduce the computation cost, we select a simple equation to implement the interpolation. The simulation results show that our method can efficiently improve the video quality over different macroblock lost rate.
