We examined how the distribution of colors in natural images varies as the seasons change.
Images of natural outdoor scenes were acquired at locations in the Western Ghats, India …

The distribution of colors in natural images can vary widely across different environments or
within the same environment over time. We have examined how color distributions at a …

Modern accounts of color appearance differ in whether they assume that the perceptual
primaries (eg, white and the unique hues of red, green, blue, and yellow) correspond to …

Color perception depends profoundly on adaptation processes that adjust sensitivity in
response to the prevailing pattern of stimulation. We examined how color sensitivity and …

The perceptual color qualities of hue, saturation, and brightness do not correspond in any
simple way to the physical characteristics of retinal stimuli, a fact that poses a major obstacle …

To what extent do observers' judgments of surface color with natural scenes depend on
global image statistics? To address this question, a psychophysical experiment was …

Primate visual systems support an elaborate specialization for processing color information.
Concentrating on the hue component, we observe that, contrary to Mondrian-like …

To study the characteristics of color memory for natural images, a memory-identification task
was performed with differing color contrasts; three of the contrasts were defined by chromatic …

Color vision supports two distinct visual functions: discrimination and constancy.
Discrimination requires that the visual response to distinct objects within a scene be …

A biologically-based multistage neural network is presented which produces color constant
responses to a variety of color stimuli. The network takes advantage of several mechanisms …
