Mechanisms of color constancy.

چکیده
We develop a model of how the visual system finds the colors of objects that have unknown shapes and positions. The model relies on mechanisms of light adaptation, coupled with eye movements, to recover three descriptors of surface reflectance that are represented in the signals of an achromatic mechanism and two color-opponent mechanisms. These descriptors are transformed to yield estimates of hue, the dimension of surface color that is independent of object shape and viewing geometry.

A Study of Relationship Between Color Inconstancy Level and CIELAB Color Coordinates
In commercial point of view, it is of great interest to find colors with high color constancy level. Color constancy as a relatively property of object’s appearance could be affected by different factors. In this article, the color inconstancy index of CMCCON02 and CIELAB color coordinate of 1269 samples of Munsell at CIELchº color system to study any correlations, was calculated. The correspon...
متن کاملIndividual differences in simultaneous color constancy are related to working memory.
Few studies have investigated the possible role of higher-level cognitive mechanisms in color constancy. Following up on previous work with successive color constancy [J. Exper. Psychol. Learn. Mem. Cogn. 37, 1014 (2011)], the current study examined the relation between simultaneous color constancy and working memory-the ability to maintain a desired representation while suppressing irrelevant ...
متن کاملMechanisms of color constancy under nearly natural viewing.
Color constancy is our ability to perceive constant surface colors despite changes in illumination. Although color constancy has been studied extensively, its mechanisms are still largely unknown. Three classic hypotheses are that constancy is mediated by local adaptation, by adaptation to the spatial mean of the image, or by adaptation to the most intense image region. We measure color constan...
متن کاملA Physical Basis for Color Constancy
A fundamental problem in psychophysical experiments is that significant conclusions are hard to draw due to the complex experimental environment necessary to examine color constancy. An alternative approach to reveal the mechanisms involved in color constancy is by modeling the physical process of spectral image formation. In this paper, we aim at a physical basis for color constancy rather tha...
متن کاملColor constancy from physical principles
A well known property of human vision, known as color constancy, is the ability to correct for color deviations caused by a difference in illumination. A common approach to investigate color constant behavior is by psychophysical experiments, regarding the human visual system as a black box responding to a well defined change in an laboratory setup. A fundamental problem in psychophysical exper...
متن کاملPixel and spatial mechanisms of color constancy
Color constancy remains an important subject of research on color standards, computer imaging, and human color vision. There are many different theories and algorithms that interpret and predict constancy. This paper analyzes three different approaches that are frequently discussed separately in the literature: pixel-based colorimetric standards of appearance; computer imaging calculations of a...
