Matrix R of linear-group tristimulus invariants, presented by Cohen and Friden (1976) and Cohen and Kappauf (1982), was decomposed into functions of simplert ristimulusv olume ratios( alsol inear-groupin variants)S. uch volume ratios were applied to the dual problems of color constancy and illuminantinvariant object-color recognition by an artificial trichromatic photosensor. The proof of the decomposition theorem relies on a lemma used in previous work elucidating the conditions for illuminant-invariance of clockwise/ counterclockwise ordering of triads of object colors in chromaticity space.
