Saturation improvement in hue-preserving color image enhancement without gamut problem

ICT Express, 2018
This study proposes a method to improve the saturation of colors during hue-preserving color image enhancement without the gamut problem. First, the color of each pixel in an input image is projected onto one of three bisecting planes or bisectors of an ...

High‐Chroma Color Coatings Based on Ag/SiO2/Ti/SiO2 Structures

Advanced Photonics Research, 2022
A four‐layer metal–dielectric–metal–dielectric (MDMD) stack design for color control is demonstrated. This stack incorporates Ag, SiO2, and Ti as materials, enabling wide absorbance bands, high reflectance peaks, and a strongly tunable color.

A two‐stage hue‐preserving and saturation improvement color image enhancement algorithm without gamut problem

IET Image Processing, 2023
A novel hue‐preserving and color enrichment color image enhancement algorithm without gamut problem is proposed in this paper. First, the pixel values of the input image are stretched to the edge of RGB color space to improve the saturation.

Ultra-Wide Color Gamut of Three-Primary and Four-Primary Laser-Based Displays With Large Circadian Tunability

IEEE Photonics Journal, 2023
A numerical and optimization study has been well performed on both the circadian effect and color gamut of laser-based displays (LBDs) consisted of multiple-primary laser diodes (LDs) to realize the ultra-wide color gamut. The LBDs mainly consist of red (
