Uniform color space as a function of spatial frequency

摘要

Abstract: A vision model is presented that combines a model for human color perception and visual adaptation with a model for the achromatic and chromaticity modulation transfer functions of the visual system. The combined models produce a uniform color space that can be described as a function of spatial frequency. This model may be useful in developing and optimizing image compression algorithms to reduce bit rate and to increase the quality of color images. !19
