Post filtering methods for reducing blocking effects from coded images
Tiina Jarske, Petri Haavisto, Irek Defee · IEEE Transactions on Consumer Electronics · 1994
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.>
