An Effective Error Concealment Method Based on the Scene Change

Abstract

This paper proposes a novel error concealment method based on the scene change in H.264. An effective scene change detection mechanism is adopted firstly in this method to detect the scene change. Temporal error concealment is chosen when the temporal redundancy is greater than the spatial redundancy. Otherwise, spatial error concealment is chosen. This method improves the original method of error concealment in H.264. The experiment results demonstrate that the visual quality of image and PSNR are significantly improved.
