Color preference and perceived color naturalness of digital videos
SPIE Proceedings, 2006In this study, we examined the subjective attributes of color preference and perceived naturalness of digital videos when the chroma of the color content was varied. More specifically, the objectives were: (1) to determine how the scaling of color chroma affected the mean color preference rating and the mean naturalness rating across subjects and (2 ...

Electromagnetic waves can have many different wavelengths and frequencies in a range known as the electromagnetic spectrum, as illustrated in Fig. 1.1. Light is a narrow range of electromagnetic waves that the eye can detect. Different wavelengths of light produce different perceptions of color.

A natural norm for color processing
1997We show that the geometrical framework, in which color images are considered as surfaces, results in a meaningful operator for enhancing color images. The area functional, or “norm”, captures the way we would like the smoothing process to act on the different color channels while exploring the coupling between them.

Natural Food Pigments and Colorants
Current Opinion in Food Science, 2016The natural color of foods is due primarily to carotenoids, anthocyanins, betanin and chlorophylls, either as inherent food constituents or as food or feed additives. These compounds have drawn considerable attention in recent years, not because of their coloring properties, but due to their potential health-promoting effects.

Color classification of natural color images
Color Research & Application, 1992AbstractThe present article describes a color classification method that partitions a color image into a set of uniform color regions. The input image data are first mapped from device coordinates into the CIE L*a*b* color space, an approximately uniform perceptual color space.
