Patch Based Image Completion for Compression Application

Abstract

A new technique for the filling-in of missing blocks in wireless transmission of block based compressed images is proposed. By intentionally (and automatically) dropping image blocks and using filling-in approach, the performance of the compression ratio can be improved. The approach removes only partial regions in the image and generates a smaller image of same size as the original. This provides the condensed description of an image. Intuitively, the approach at decoder side restores large dropped regions utilizing the correlations between image patches. Thus, patch manipulation technique enhances the compression ratio of still images by recovering the damaged portions of an image.
