Abstract

To efficiently recover the lost motion vectors of corrupt macro- blocks, we introduce a new fuzzy metric based on Sugeno fuzzy integral as distortion metric in temporal error concealment. The proposed fuzzy metric can suit the HVS (human visual system) fairly well. Also, we integrate the proposed algorithm into H.264/AVC decoder. Experimental results from decoding several types of video sequences have shown that our scheme can considerably improve the visual quality of reconstructed images and achieve the PSNR gain at different frame.
