Fuzzy-controlled coding method and apparatus therefor

摘要

A fuzzy-controlled coding method and apparatus thereof wherein quantization step size which is determined by values of image complexity, buffer fullness, motion vector and picture brightness, is controlled by using a fuzzy reasoning and defuzzification, enables properly dealing with the case where the conditions which influence a quantization step size deviate from the conventional algorithm established in a system. As a result, the image restored by decoding has a stable image quality. <IMAGE>
