摘要
Most viable modern chromatic adaptation transforms(CATs),such as CAT16 and CAT02,can trace their roots both conceptually and mathematically to a simple model formulated from the hypotheses of Johannes von Kries in 1902,known as the von Kries transform/model.However,while the von Kries transform satisfies the properties of symmetry and transitivity,most modern CATs do not satisfy these two important properties.In this Letter,we propose a generalized von Kries transform,which satisfies the symmetry and transitivity properties in addition to improving the fit to most available experimental visual datasets on corresponding colors.
