Abstract:
The criter ia of image quality evaluat io n play an important role in digital image pro cessing . Since human being is the f inal receiver of o utput of digital image pr ocessing , the char acterist ics o f human visual system( HVS ) must be incorporated into the criter io n of imag e qual ity ev aluat ion. In this paper , w avelet tr ansform is used because it matches w ell w ith the mult ichannel model of HVS. A new criterion of imag e quality evaluat ion is pro po sed based on the visibility thr esho ld model in w av elet t ransform domain. Result s of experimental stimulat ion are compared w ith one of the ordinary cr iteria, and are show n to be consistent w ith the subject ively perceptual imag e quality .
