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 …

Vision provides information about the properties and identity of objects. The ease with which
we perceive object properties belies the difficulty of the underlying information-processing …

The first stage of color vision is now well understood (see Chap. 10). When presented in the
same context under photopic conditions, pairs of lights that produce the same excitations in …

Vision is difficult because images are ambiguous about the structure of the world. For object
color, the ambiguity arises because the same object reflects a different spectrum to the eye …

We examined visual estimation of surface roughness using random, computer-generated,
three-dimensional (3D) surfaces rendered under a mixture of diffuse lighting and a punctate …

Two experiments explore the color perception of objects in complex scenes. The first
experiment examines the color perception of objects across variation in surface gloss …

Perceiving material properties can be crucial for many tasks—such as determining food
edibility, or avoiding getting splashed—yet the visual perception of materials remains poorly …

The objects in our environment are made of a wide range of materials. The color
appearance of the objects is influenced by many factors, including the geometry of the …

All images are highly ambiguous, and to perceive 3-D scenes, the human visual system
relies on assumptions about what lighting conditions are most probable. Here we show that …

Rendering packages are used by visual psychophysicists to produce complex stimuli for
their experiments, tacitly assuming that the simulation results accurately reflect the light …
