Although luminance and color are thought to be processed independently at early stages of
visual processing, there is evidence that they interact at later stages. For example, chromatic …

Perceived depth is conveyed by multiple cues, including binocular disparity and luminance
shading. Depth perception from luminance shading information depends on the perceptual …

Using a novel approach to classification images (CIs), we investigated the visual expertise of
surveyors for luminance and binocular disparity cues simultaneously after screening for …

Invariants underlying shape inference are elusive: A variety of shapes can give rise to the
same image, and a variety of images can be rendered from the same shape. The occluding …

Two dilemmas arise in inferring shape information from shading. First, depending on the
rendering physics, images can change significantly with (even) small changes in lighting or …

We exploit a key result from visual psychophysics---that individuals perceive shape
qualitatively---to develop the use of a geometrical/topological “invariant”(the Morse--Smale …

The research described in the present article was designed to compare three types of image
shading: one generated with a Lambertian BRDF and homogeneous illumination such that …

Human observers made local orientation judgments of smoothly shaded surfaces
illuminated from different directions by large area lights, both with and without visible smooth …

There is an activity called" digital archiving" in which cultural property is digitized for
preservation and utilization, and transparent visualization using 3D point clouds is a …

The darker-is-deeper heuristic was originally proposed by Langer and Zucker (1994) for
approximating 3D shape from shading under conditions of diffuse illumination that typically …
