| 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.

| Abstract: | 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. |
