FUZZY QUANTIZATION STEP CONTROLLER FOR WAVELET-SUBBAND IMAGE CODING

Peter Planinšič

   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.

Keywords: fuzzy logic, fuzzy quantization, step controller, PSNR-picture, wavelet-subband coding
