COLORLAB is a high-performance color computation and visualization toolbox for MATLAB 5.3 or higher.
COLORLAB is intended to deal with color in general-purpose quantitative colorimetric applications as color image processing and psychophysical experimentation. COLORLAB uses colorimetrically meaningful representations of color and color images (tristimulus values, chromatic coordinates and luminance, or, dominant wavelength, purity and luminance), in any primaries system. COLORLAB relates these colorimetric representations to the usual device-dependent discrete-color representation. A number of interesting color representations are also provided, as CIE uniform color spaces (as L*a*b* and L*u*v*), opponent color representations based on advanced color vision models, and color appearance representations (RLab, LLab, SVF and CIECAMs).
