HVI: A New Color Space for Low-light Image Enhancement

Computer Vision and Pattern Recognition
Low-Light Image Enhancement (LLIE) is a crucial computer vision task that aims to restore detailed visual information from corrupted low-light images. Many existing LLIE methods are based on standard RGB (sRGB) space, which often produce color bias and ...

You Only Need One Color Space: An Efficient Network for Low-light Image Enhancement

arXiv.org
Low-Light Image Enhancement (LLIE) task tends to restore the details and visual information from corrupted low-light images. Most existing methods learn the mapping function between low/normal-light images by Deep Neural Networks (DNNs) on sRGB and HSV ...

Skin color detecting unite YCgCb color space with YCgCr color space

2009 International Conference on Image Analysis and Signal Processing, 2009
In order to detect more reliably skin color for color facial image with complicated background, we have presented a detection method based on uniting YCgCb color space with YCgCr color spaced. There exist many colors in nature that are similar to skin color, such as sand, sand beach, soil, stone, cement road, wood, and so on. The things mentioned above

Spectral spaces and color spaces

Color Research & Application, 2003
AbstractIt has long been known that color experiences under controlled conditions may be ordered into a color space based on three primary attributes. It is also known that the color of an object depends on its spectral reflectance function, among other factors.

Sculpting color spaces

ACM SIGGRAPH 2019 Talks, 2019
Color correction with a long chain of keyers and math operators, even in the hands of experienced artists, often induces artifacts such as muddy colors or malformed edges. Inspired by tools which display a 3D color histogram [COL 2007], and Flame's Color Wrapper [WRA 2019], we embarked on building a user-friendly 3D color space sculpting toolset which ...

Color spaces and color contrast

The Visual Computer, 1985
With the introduction of low-cost color graphics systems comes a host of problems specifically concerned with the color aspect of the system. This paper discusses two of these problems: the selection and manipulation of colors by (possibly) inexperienced users, and the automatic selection of colors by the system to achieve high contrast effects on the ...

Interconnections between fundamental-color spaces and opponent-color spaces

OSA Annual Meeting, 1993
A set of three spectral fundamental color functions is assumed to be available, functions that can be interpreted as spectral sensitivities of the three retinal cone types.

Developing Through-Space Charge Transfer Polymers as a General Approach to Realize Full-Color and White Emission with Thermally Activated Delayed Fluorescence.

Angewandte Chemie, 2019
Through-space charge transfer polymers (TSCT polymers) that contain a non-conjugated polystyrene backbone and spatially separated donor and acceptor units for solution-processed OLEDs with full-color and white emission is reported.
