Digital color image processing and psychophysics within the framework of a human visual model.

Abstract : A three-dimensional homomorphic model of human color vision based on neurophysiological and psychophysical evidence is presented. This model permits the quantitative definition of perceptually important parameters such as brightness, saturation, hue and strength. By modelling neural interaction in the human visual system as three linear filters operating on perceptual quantities, this model accounts for the automatic gain control properties of the eye and for brightness and color contrast effects. A psychophysical experiment was performed, using a high quality color television monitor driven by a general purpose digital computer. This experiment, based on the cancellation by human subjects of simultaneous color contrast illusions, allowed measurement of the low spatial frequency part of the frequency responses of the filters operating on the two chromatic channels of the human visual system.
