Spring-Primary Mapping: a Fast Color Mapping Method for Primary Adjustment and Gamut Mapping

摘要

A gamut mapping method, spring-primary gamut mapping, was developed for device to device color mapping. Instead of performing gamut mapping point-wisely, it selects a small number of points for gamut mapping and determines the color mapping of other points by interpolation using color similarity information. It incorporates primary adjustment and gamut mapping into a single step. Using the color similarity information of neighbor colors for color mapping, it well preserves the color to color relationship. Applying interpolation instead of gamut mapping for majority of colors, it tremendously increases the speed of gamut mapping process.
