A quarter of a century ago, the first systematic behavioral experiments were performed to
clarify the nature of color constancy—the effect whereby the perceived color of a surface …

The environments in which we live and the tasks we must perform to survive and reproduce
have shaped the design of our perceptual systems through evolution and experience …

A fundamental problem in computer vision is that of inferring the intrinsic, 3D structure of the
world from flat, 2D images of that world. Traditional methods for recovering scene properties …

An ideal observer is a hypothetical device that performs optimally in a perceptual task given
the available information. The theory of ideal observers has proven to be a powerful and …

We present SIRFS (shape, illumination, and reflectance from shading), the first unified model
for recovering shape, chromatic illumination, and reflectance from a single image. Our model …

In everyday experience, perceived colors of objects remain approximately constant under
changes in illumination. This constancy is helpful for identifying objects across viewing …

There is a large literature characterizing human perception of the lightness and color of
matte surfaces arranged in coplanar arrays. In the past ten years researchers have begun to …

We investigated whether people who report different colors for# thedress do so because
they have different assumptions about the illumination in# thedress scene. We introduced a …

Illumination in natural scenes changes at multiple temporal and spatial scales: slow
changes in global illumination occur in the course of a day, and we encounter fast and …
