Color constancy supports cross-illumination color selection.
We rely on color to select objects as the targets of our actions (e.g., the freshest fish, the ripest fruit). To be useful for selection, color must provide accurate guidance about object identity across changes in illumination. Although the visual system partially stabilizes object color appearance across illumination changes, how such color constancy supports object selection is not understoo...
متن کاملColor constancy in the nearly natural image. I. Asymmetric matches.
Most empirical work on color constancy is based on simple laboratory models of natural viewing conditions. These typically consist of spots seen against uniform backgrounds or computer simulations of flat surfaces seen under spatially uniform illumination. We report measurements made under more natural viewing conditions. The experiments were conducted in a room where the illumination was under...
متن کاملColor constancy: surface color from changing illumination
Received September 5, 1991; revised manuscript received October 30, 1991; accepted November 13, 1991 Viewing the lights reflected by a set of three or more surfaces, a trichromatic visual system can recover three color-constant descriptors of reflectance per surface if the color of the surfaces' illuminant changes. This holds true for a broad range of models that relate photoreceptor, surface, ...

متن کاملMultiple Color Matches to Estimate Human Color Vision Sensitivities
A color matching experiment was designed and carried out to estimate human observers’ color matching functions (CMFs). 61 colornormal observers participated in the experiment. Their results were traced back to physiological factors using a mathematical vision model. The experiment time was 15 minutes, which is much faster than previous research aimed at determining color matching functions.
