by Reducing Interblock Correlation
Kyoung Won Lim, Kangwook Chun, Jong Beom Ra · 1995
Absfmcf-In this correspondence, we try to improve transform coding efficiency by alleviating interblock correlation due to the small size of block. The proposed method needs minor modification from conventha1 transform coding techniques such as PEG, and reduces information loss in the coding procedure for a given bit rate. Simulation results demonstrate that the method drastically diminishes the blocking effects and enhances the subjective visual quality compared with such existing algorithms as JPEG and LOT.
