The color of night: Surface color perception under dim illuminations.
Several studies document rudimentary color vision under dim illumination. Here, hue perceptions of paper color samples were determined for a wide range of light levels, including very low light levels where rods alone mediate vision. The appearances of 24 paper color samples from the OSA Uniform Color Scales were gauged under successively dimmer illuminations from 10-0.0003 Lux. Triads of sampl...
متن کاملThe color of night: surface color categorization by color defective observers under dim illuminations.
People with normal trichromatic color vision experience variegated hue percepts under dim illuminations where only rod photoreceptors mediate vision. Here, hue perceptions were determined for persons with congenital color vision deficiencies over a wide range of light levels, including very low light levels where rods alone mediate vision. Deuteranomalous trichromats, deuteranopes and protanope...
متن کاملColor perception under chromatic adaptation: "supersensitivity" with dim backgrounds.
The amounts of 540 nm light and 660 nm light that when mixed result in a yellow (neither reddish nor greenish) percept remain in constant ratio, regardless of the total retinal illumance level of the mixture. A similar result holds if the mixture is superimposed upon a very dim 660 nm adapting field, except that a larger proportion of 540 nm light is required than in the dark (contrary to an ef...
متن کاملColor Texture Classification under Different Illuminations Using Rank Correlation Matrices
Color has been shown to be useful in the context of texture classification. However, since under different illuminations color is not stable, color invariant descriptors should be defined when the illumination of the query is unknown. In this paper, we propose to characterize color textures by analyzing the rank correlation of color planes between pixels locally close to each other. Thus, consi...
متن کاملColor blindness and its illuminations
In 1974, not long after an antenna was implanted in his skull, the British artist Neil Harbisson became the first person in history to be officially recognized as a cyborg.1 A cyborg—short for cybernetic organism—is a living thing formed from the integration of organic and mechanical parts. Before becoming a cyborg, Harbisson struggled as an art student afflicted with achromatopsia, an extremel...
