A growing body of evidence suggests that the brain computes lightness in a two-stage
process that involves (1) an early neural encoding of contrast at the locations of luminance …

One of the primary functions of visual perception is to represent, estimate, and evaluate the
properties of material surfaces in the visual environment. One such property is surface color …

A model of achromatic color computation by the human visual system is presented, which is
shown to account in an exact quantitative way for a large body of appearance matching data …

Recent theories of lightness perception assume that lightness (perceived reflectance) is
computed by a process that contrasts the target's luminance with that of one or more regions …

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

The filling-in theory of brightness perception has gained much attention recently owing to the
success of vision models. However, the theory and its instantiations have suffered from …

Previous work has demonstrated that perceived surface reflectance (lightness) can be
modeled in simple contexts in a quantitatively exact way by assuming that the visual system …

Establishing the computational rules and neural substrates of brightness coding is a topic of
both historical and contemporary interest. Two major classes of explanations for brightness …

As has been observed by Wallach (1948), perceived lightness is proportional to the ratio
between the luminances of adjacent regions in simple disk-annulus or bipartite scenes. This …

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 …
