How the human visual system determines the lightness of a surface, that is, its whiteness,
blackness, or grayness, remains--like vision in general--a mystery. In fact, we have not even …

A fundamental goal of research in the perception of surfaces is to understand the nature of
the computations and representations underlying lightness perception. A significant …

To recover surface reflectance and illuminance from the raw luminance signal, the visual
system must use prior assumptions and strategies that make use of additional sources of …

Lightness perception has mainly been studied with static scenes so far. This study presents
four experiments investigating lightness perception under dynamic illumination conditions …

Research in lightness perception centers on understanding the prior assumptions and
processing strategies the visual system uses to parse the retinal intensity distribution (the …

Contrary to the implication of the term “lightness constancy”, asymmetric lightness matching
has never been found to be perfect unless the scene is highly articulated (ie, contains a …

This article deconstructs the conventional theory that “brightness” and “lightness” constitute
perceptual dimensions corresponding to the physical dimensions of luminance and …

Abstract According to Koffka (1935), the lightness of a target surface is determined by the
relationship between the target and the illumination frame of reference to which it belongs …

Natural scenes often contain variations in local luminance as a result of cast shadows and
illumination from different directions. When making judgments about such scenes, it may be …

Luminance ratios along shadow edges remain the same even when they cross reflectance
borders. According to Gilchrist (1988, Perception & Psychophysics 43 415–424) this so …
