<title>Color photometry by optical image processing</title>

Abstract

It has been proposed the color photometry, which is based upon the metric vector color space, the nonlinear transformation of color responses in the visual system and multistage opponent-colors theory. The model of color vision system are given. The fundamental light and color units of color photometry are determined simply: color luminance, color amplitude, light, hue, saturation, and others. The mathematical formula of their interaction are represented. The color photometry involves taking into account all three of the photoreceptors responses by day light and their vector addition, which is a fundamental property of the visual system.
