A novel temporal error concealment framework in H.264/AVC

摘要

In this paper, we propose a novel framework for temporal error concealment in H.264/AVC. The proposed framework combines the properties of Skip Mode and Intra Mode in H.264/AVC Inter frame and robust motion inpainting in the computer vision community. In our framework, modes of the correctly received surrounding blocks of the missing macroblocks are checked first. If Intra Mode or Skip Mode blocks exist, depending on the boundary matching results, motion compensation based temporal error concealment method is used to conceal the missing macroblocks. Otherwise, improved robust motion inpainting based error concealment method is used to conceal the missing macroblocks. Experiments on several videos show visually pleasing results and low computation cost.
