Abstract :
A new technique of information-restoration for the block-based images is proposed. This scheme is based on fuzzy reasoning and aims at intra frame error concealment for gray level images. Fuzzy reasoning is applied to classify the results of pixel matching and then the pixel correction is managed to modify the pixel values of the blocks with low RED (recover exactness degree). The experiment results show the effectiveness of our proposed method.
