IMPROVEMENT ON IMAGE TRANSFORM CODING BY REDUCING INTERBLOCK CORRELATION

In this correspondence, He try to improve transform coding efficiency by alleviating interblock correlation due to the small size of block. The proposed method needs minor modification from conventional transfo rm coding techniques such as JPEG, 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 enhan ces the subjective visual quality compared with such existing algorith ms as JPEG and LOT.
