The Color Logarithmic Image Processing (CoLIP) Antagonist Space and Chromaticity Diagram

The CoLIP framework defines a vectorial space for color images. It is in accordance with the theories of visual perception (Weber, Fechner) as well as Hering’s trichromacy theory. It is mathematically well defined and computationally usable. This article recalls the fundamentals of the LIP framework for graytone images, and introduces the elementary operations of the vectorial structure for color images. It illutrates the representation of the chromaticity diagram with color modification application, namely white balance correction and color transfer. The results show that the hull of the diagram are not modified, but the colors are.
