Chromatic contrast detection in spatial chromatic noise.
The spectral properties of chromatic-detection mechanisms were investigated using a noise-masking paradigm. Contrast-detection thresholds were measured for a signal with a Gaussian spatial profile, modulated in the equiluminant plane in the presence of spatial chromatic noise. The noise was distributed within a sector in the equiluminant plane, centered on the signal direction. Each stimulus co...
متن کاملSignal Detection in Fixed Pattern Chromatic Noise
This study is part of a project to develop image discrimination models that can predict the detectability of target signals in color images. Image discrimination models take as input two images and predict the number of just-noticeable differences (JNDs) between the images. If one image is a background image and the other image has the identical background plus a target image, the model predict...
متن کاملV1 mechanisms underlying chromatic contrast detection.
To elucidate the cortical mechanisms of color vision, we recorded from individual primary visual cortex (V1) neurons in macaque monkeys performing a chromatic detection task. Roughly 30% of the neurons that we encountered were unresponsive at the monkeys' psychophysical detection threshold (PT). The other 70% were responsive at threshold but on average, were slightly less sensitive than the mon...
متن کاملChromatic induction with remote chromatic contrast varied in magnitude, spatial frequency, and chromaticity
Chromatic induction from a surround is attenuated by chromatic contrast within a remote region outside of the surround (Shevell & Wei, 1998, Vision Research, 38, 1561-1566). The present study reports hue-cancellation measurements that show the attenuation depends on the magnitude, spatial frequency and chromaticity of remote chromatic contrast. Spatial-frequency tuning is shown by maximal atten...
متن کاملChromatic and luminance interactions in spatial contrast signals.
We report VEP studies which delineate interactions between chromatic and luminance contrast signals. We examined responses to sinusoidal luminance gratings undergoing 4-Hz square-wave contrast reversal, upon which standing gratings with various admixtures of luminance and chromatic contrast were alternately superimposed and withdrawn. The presence of the standing grating induced a VEP component...
