Abstract

We introduced color enhancement factors to control the spectral power distribution of illumination, which enabled us to enhance one or more colors at once while retaining the color appearance of white. In experiments, color enhancement factors corresponding to red, green, and blue were calculated using color patches of a color chart and used for controlling a sixteen-color LED lighting system. The color chart and an old wood-block print were illuminated by the modulated light from the lighting system. By changing only three parameters, each color was enhanced continuously and independently with metameric white and the color balance under daylight maintained.

Illumination Estimation Based Color Contrast Enhancement
IIH-MSP '12: Proceedings of the 2012 Eighth International Conference on Intelligent Information Hiding and Multimedia Signal Processing

We present the framework for a color contrast enhancement using an illumination estimation, color balancing and color dynamic range expansion based on characteristics of a object reflectance, effect of illumination and human face color depending on ...
Color image enhancement with high saturation using piecewise linear gamut mapping
Abstract
Most of the color image enhancement algorithms are implemented in two stages: gray scale image enhancement, which finds the target intensity, and then gamut mapping of the original color coordinates to the target. Therefore, hue ...
Background Adjustment and Saturation Enhancement in Ancient Chinese Paintings

This work presents a color enhancement scheme to virtually restore ancient Chinese paintings in electronic form. Two degradations result in color contrast loss in ancient Chinese paintings: paper aging and pigment fading. The proposed enhancement scheme ...
