FUZZY QUANTIZATION STEP CONTROLLER FOR WAVELET-SUBBAND IMAGE CODING
The fuzzy quantization step controller for achieving a desired PSNR-picture quality
measure in wavelet-subband coding is described. Other possibilities for the use of fuzzy
logic to control the picture quality are mentioned, eg construction of a complex
picture quality measure and the fuzzy bit allocation.
