In low bit-rate applications, MPEG based compressed video exhibits annoying coding artifacts. In this paper, image recovery algorithms based on the theory of projections onto convex sets are proposed to decode video images from MPEG data without coding artifacts. According to this approach, each video frame is reconstructed using not only the transmitted data but also other prior knowledge which is available and not explicitly used by the conventional MPEG decoding algorithm. Numerical experiments demonstrate that the proposed algorithm yield images superior to those from conventional MPEG decoders.
