Color memory and color constancy.
Color constancy is the perceived stability of the color of objects despite changes in the light illuminating them. An object's color is considered constant if the current perceived color is judged to be in accord with the remembered one. Thus the accuracy and precision of color memory are fundamental to understanding this classic problem. Two hypotheses of color memory are tested here: (1) the ...
متن کاملColor constancy
A quarter of a century ago, the first systematic behavioral experiments were performed to clarify the nature of color constancy-the effect whereby the perceived color of a surface remains constant despite changes in the spectrum of the illumination. At about the same time, new models of color constancy appeared, along with physiological data on cortical mechanisms and photographic colorimetric ...
متن کاملColor constancy and the complexity of color ∗
We can start with a definition. “[C]olour constancy is the constancy of the perceived colours of surfaces under changes in the intensity and spectral composition of the illumination.” (Foster et al. 1997) Given the definition we can now ask a question: Does human color vision exhibit color constancy?1 The answer to the question depends in part on how we interpret it. If the question is understo...
متن کاملColor constancy: surface color from changing illumination
Received September 5, 1991; revised manuscript received October 30, 1991; accepted November 13, 1991 Viewing the lights reflected by a set of three or more surfaces, a trichromatic visual system can recover three color-constant descriptors of reflectance per surface if the color of the surfaces' illuminant changes. This holds true for a broad range of models that relate photoreceptor, surface, ...
متن کاملSupervised color constancy using a color chart
One of the key problems in machine vision is color constancy: the ability to match object colors in images taken under different colors of illumination. This is a difficult problem because the apparent color will depend upon the spectral reflectance function of the object and the spectral distribution function of the incident light, both of which are generally unknown. Methods to solve this pro...
