A novel method for blocking effect reduction in DCT-coded images

By Wing-Kuen Ling and Bing Zeng


In this paper, a novel method for blocking effect reduction in DCTcoded images is presented. A block image is first transformed into DCT domain, then some of the DCT coefficients are set to zero or multiplied by some weighting coefficents. Intensive simulations show a respectable performance for both one dimension and two\ud dimension cases
