In this paper, we proposed an efficient frame loss error concealment scheme based on reverse projection. Frame loss often happens in low bit-rate video transmissions. This method utilized bi-direction motion vector extrapolation to generate a coverage motion vector candidate list. Then each motion vector in the candidate list is tentatively projected into the previous frame and the next frame. A distortion estimation is used to choose a best MV from the previous and the next frame each. A final MV is obtained with a liner interpolation of the chosen MVs. Experimental results have demonstrated that the proposed method improves the objective performance in terms of PSNR as well as subjective visual quality and the tentative projection is efficient.
