Estimating the color of the illuminant under which an image of a scene was captured is a central part of solving the color constancy problem: that is, of deriving an illuminant independent representation of the reflectance's in a scene. In this article we develop a general correlation framework for solving the illuminant estimation problem. Within this

Form constancy denotes the appearance of the invariant shape of objects in the environment, notwithstanding the variability due to changes of the viewpoint, caused by subjects movement, to objects displacement, to illumination, lightness, color, and texture whose variation can affect the internal and external boundaries of the surfaces that fall in the

A variable behaves as a step-function over some given period of observation if it changes value at only a finite number of discrete instants, at which it changes value instantaneously and by a finite jump.

The Effect of Refractive Error on Size Constancy and Shape Constancy
Perception, 1978The effect of refractive error was determined for both size constancy and shape constancy. Although an error of 1·5 diopters reduces shape constancy, 3·0 diopters of blur had no effect on size constancy. The results are discussed in terms of the multiple mechanisms subserving the perceptual constancies.
