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

To maintain color constancy, the human visual system must distinguish surface reflectance-
based variations in wavelength and luminance from variations due to illumination. Edge …

Abstract Brill and Carter [Color Res Appl (DOI: 10.1002/col21777)] rekindle the question of
whether brightness scaling is better approximated by a log or power function, proposing on …

Simultaneous contrast refers to the respective whitening or blackening of physically identical
image regions surrounded by regions of low or high luminance, respectively. A common …

It has been hypothesized that lightness is computed in a series of stages involving:(1)
extraction of local contrast or luminance ratios at borders;(2) edge integration, to combine …

Classical approaches to transparency perception assume that transparency constitutes a
perceptual dimension corresponding to the physical dimension of transmittance. Here I …

We report a series of experiments that employed chromatic variants of lightness illusions in
an attempt to gain theoretical leverage into the types of computations that are responsible for …

Lightness perception is the ability to perceive black, white, and gray surface colors in a wide
range of lighting conditions and contexts. This ability is fundamental for any biological or …

Human lightness percepts are often remarkably stable despite variations in illumination and
spatial context. But human lightness constancy is not perfect (Gilchrist et al., 1999). Many …

This volume deals with the visual perception of lightness, brightness, and transparency of
surfaces, both under minimal laboratory conditions and in complex images typical of …
