Abstract :
The authors propose an efficient perceptual adaptive quantisation scheme that uses Q-N (quantisation step-number of output bits) mapping tables and fuzzy perceptual classifiers. Using this adaptive quantisation scheme, stable perceptual quality and good visual effects can be obtained at a constant output bit rate
