Higher order color mechanisms

Vision Research, 1986
Evidence supporting the existence of higher order color mechanisms, that is, ones beyond the previously identified second stage mechanisms is presented. This evidence includes a reanalysis of the data of Krauskopf et al. [Vision Res. 20, 1123-1131 (1982)] on the desensitizing effects of viewing chromatically modulated fields, new experiments on a ...

Mechanisms of simultaneous color induction

Journal of the Optical Society of America A, 1986
A new method of measuring simultaneous contrast, or chromatic induction, is introduced and used to test the hypotheses that induction results from either multiplicative or subtractive interaction of either like receptors or like second-stage, opponent mechanisms. Predictions derived from these hypotheses do not predict the outcome of the experiments as

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.
