Spatial filtering models are currently a widely accepted mechanistic account of human
lightness perception. Their popularity can be ascribed to two reasons: They correctly predict …

White's illusion is the perceptual effect that two equiluminant gray patches superimposed on
a black-and-white square-wave grating appear different in lightness: A test patch placed on …

The apparent lightness of a surface can be strongly modulated by the spatial context in
which it is embedded. Early theories of such context dependence emphasized the role of …

We introduce two new low-level computational models of brightness perception that account
for a wide range of brightness illusions, including many variations on White's Effect …

Lightness, or perceived reflectance of a surface, is influenced by surrounding context. This is
demonstrated by the Simultaneous Contrast Illusion (SCI), where a gray patch is perceived …

The oldest lightness illusion is called simultaneous contrast. A gray square placed on a
black background appears lighter than an identical gray square placed on a white …

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 …

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 …

One approach toward understanding how vision computes surface lightness is to first
determine what principles govern lightness in simple stimuli and then test whether these …

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 …
