Hue Guidance Network for Single Image Reflection Removal
IEEE Transactions on Neural Networks and Learning Systems, 2023Reflection from glasses is ubiquitous in daily life, but it is usually undesirable in photographs. To remove these unwanted noises, existing methods utilize either correlative auxiliary information or handcrafted priors to constrain this ill-posed ...

It is generally accepted that hues can be arranged so as to make a circle. The circular representation of hue has been supported by multidimensional scaling, which allows for the representation of a set of colored papers as a configuration in a Euclidean space where the distances between the papers correspond to the perceptual dissimilarities between ...

Hue discrimination, unique hues and naming
Journal of the Optical Society of America A, 2012The hue discrimination curve (HDC) that characterizes performances over the entire hue circle was determined by using sinusoidally modulated spectral power distributions of 1.5 c/300 nm with fixed amplitude and twelve reference phases. To investigate relationship between hue discrimination and appearance, observers further performed a free color naming

Relative contributions of melanopsin to brightness discrimination when hue and luminance also vary.
Journal of The Optical Society of America A-optics Image Science and Vision, 2020A large number of studies have shown the effect of melanopsin-dependent retinal ganglion cells on humans performing brightness discrimination tasks. These studies often utilized targets that only differ in their melanopsin activation levels, and not in ...

The Black Arts movement developed as a counterpart to the Black Power Movement in the 1960s and 1970s, and African American cartoonists incorporated Afrocentric themes in their work. The most prominent periodical during the Black Arts movement was Black World magazine.

Unique hues as revealed by unique-hue selecting versus partial hue-matching
Attention, Perception, & Psychophysics, 2013Unique hues are usually defined as those that cannot be introspectively reduced to any other hue. According to a major dogma of color science, there are four unique hues: yellow, blue, red, and green. Yet only 55 of the 173 inexperienced observers who participated in our experiment selected exactly four Munsell papers that, according to their judgment,

Fine-Tuning the Color Hue of π-Conjugated Black-to-Clear Electrochromic Random Copolymers
Macromolecules, 2019A family of dioxythiophene (DOT)-based conjugated random copolymers, capable of reversibly switching between a neutral black and an oxidized transmissive state, are reported for electrochromic (EC) applications.

Unique hues and principal hues
Color Research & Application, 2018AbstractThis note examines the different concepts of encoding hue perception based on four unique hues (like NCS) or five principal hues (like Munsell). Various sources of psychophysical and neurophysiological information on hue perception are reviewed in this context and the essential conclusion that is reached suggests there are two types of hue ...

Hue can be described by four separate sensations of red (R), green (G), yellow (Y), and blue (B). These are combined in the spectrally opponent RG and YB mechanisms, whose null points correspond to the unique sensations of Y, G, B. Participants used a form of magnitude estimation to describe color appearance of light flashes that were systematically ...
