In this paper we propose an edge-directed error concealment (EDEC) algorithm, to recover lost slices in video sequences encoded by flexible macroblock ordering. First, the strong edges in a corrupted frame are estimated based on the edges in the neighboring frames and the received area of the current frame. Next, the lost regions along these estimated edges are recovered using both spatial and temporal neighboring pixels. Finally, the remaining parts of the lost regions are estimated. Simulation results show that compared to the existing boundary matching algorithm [1] and the exemplar-based inpainting approach [2] , the proposed EDEC algorithm can reconstruct the corrupted frame with both a better visual quality and a higher decoder peak signal-to-noise ratio.
