Mechanism of Color Breakup on Field‐Sequential Color Projectors

SID Symposium Digest of Technical Papers, 1999
Abstract To investigate color breakup on field‐sequential color projector, we measured threshold of color fusion frequency to retinal velocity of the moving edge on the color flicker filed. The characteristic changed in the velocity as saccade.

Color contrast: a contributory mechanism to color constancy

2004
Color constancy--by which objects tend to appear the same color under changes in illumination--is most likely achieved by several mechanisms, operating at different levels in the visual system. One powerful contributory mechanism is simultaneous spatial color contrast.

Mechanisms of central color vision

Current Opinion in Neurobiology, 1998
In monkey cerebral cortex, color information is processed along the ventral visual pathway. This pathway starts in the primary visual cortex and ends in area TE of the inferior temporal cortex. Recent studies indicate that the transformation of cone signals occurs early in the pathway to form neurons selective to a narrow range of hues. In addition, it

Retinal mechanisms of color vision

Vision Research, 1964
Abstract Over a century and a half ago Young (1802) theorized that color discrimination is mediated by three photoreceptor substances, each maximally sensitive to a different region of the spectrum, and that the activity of each of these substances is somehow communicated in a unique fashion to the brain.

Uniform color space based on color vision mechanisms

SPIE Proceedings, 2002
A uniform color space based on color vision mechanisms was proposed. The mechanisms considered to construct the uniform color space were, proportion of three types of cones, compressive response nonlinearity at receptor and post- receptor stages, constant noise or dark response added to the receptor response, and fractional expressions of opponent and ...

Efficient Color Boundary Detection with Color-Opponent Mechanisms

2013 IEEE Conference on Computer Vision and Pattern Recognition, 2013
Color information plays an important role in better understanding of natural scenes by at least facilitating discriminating boundaries of objects or areas. In this study, we propose a new framework for boundary detection in complex natural scenes based on the color-opponent mechanisms of the visual system.

Cone mechanisms underlying the color discrimination of deutan color deficients

Vision Research, 1985
An alternation method of color matching was used to obtain a series of extended Rayleigh matches from several deutan color deficients with varying degrees of color discrimination. With large stimulus fields there were differences in the matches made by observers with good color discrimination and the matches made by observers with poor color ...

Mechanisms of color vision.

Critical reviews in neurobiology, 1988
We review the physiological and psychophysical research on mechanisms of color vision. Psychophysical work has led to the formulation of explicit theories of the early stages of color vision. The principal postulates of these theories have been confirmed by physiologists (e.g., the existence of three classes of receptors and second-stage mechanisms in ...

Quantum chromodynamics with colored Higgs mechanism

Physical Review D, 1985
We derive, in the context of a previously proposed chiral soliton bag model with colored Higgs mechanism, the field equations for the eight gluons and the remaining four Higgs particles. It is pointed out that the boundary condition used by Jaendel for supporting his claim about the lack of a suppression mechanism for open-color states do not follow ...
