The paper presents a novel spatial error concealment algorithm based on directional decision and intra prediction. Unlike previous approaches that simultaneously recover the pixels inside a missing macroblock (MB), we propose to recover them 4/spl times/4 block by 4/spl times/4 block. Each missing 16/spl times/16 MB in an intra frame is first divided into 16 blocks, each with size 4/spl times/4, then recovered block by block using Intra/spl times/4 prediction. Previously-recovered… CONTINUE READING
