A review of the field of lightness perception from Helmholtz to the present shows the most
adequate theories of lightness perception to be the intrinsic image models. Nevertheless …

The modern study of perception began when Fechner published his 'Elements of
Psychophysics' in 1860. This book has guided most perception research ever since. It has …

In this paper, we propose a simple but effective image prior-dark channel prior to remove
haze from a single input image. The dark channel prior is a kind of statistics of outdoor haze …

A gray surface in sunlight may have much higher luminance than it has in the shade, but it
still looks gray. To achieve the task of “lightness constancy,” the visual system must discount …

Theories of Visual Perception 3rd Edition provides clear critical accounts of several of the
major approaches to the challenge of explaining how we see the world. It explains why …

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 …

Background: The perceived color at each point in a visual scene depends on the
relationship between light signals from that point, and light signals from surrounding areas of …

Abstract Changes of annulus luminance in traditional disk-and-annulus patterns are
perceptually ambiguous; they could be either reflectance or illuminance changes. In more …

Augmented reality (AR) systems aim to alter our view of the world and enable us to see
things that are not actually there. The resulting discrepancy between perception and reality …

Various demonstrations show that a target of constant luminance can be made to appear
darker in perceived lightness merely by introducing an adjacent region of higher luminance …
