Abstract

Computationally simple post-filtering methods for block-coded image sequences are presented. Post-filtering design requires compromises between smoothing the block edges and retaining the image sharpness. The proposed filters offer a feasible method to improve the subjective quality of image sequences coded at low bit rates
