Abstract
The purpose of this study is: first, to measure the properties of human vision under conditions that are subject to "chromatic adaptation"; second, to compare the human visual properties to a number of different Retinex models. In particular, the experiments study Gray-world properties of Mondrians. Models using averages of radiance or Gray-world assumptions do not show good correlation with observers. Nonlinear, reset models of lightness normalize each pixel to the maxima in each waveband. Triplets of normalized lightness do show good correlation with observer color matches.
