Transforming an analytically defined color space to match psychophysically gained color distances

In this paper a new method for defining a transformation between a source color space and a more perceptual uniform color space is presented. The main idea is to use a three dimensional free-form deformation to deform a source color space in such a way, that the new distances between chosen color samples match psychophysically estimated data as close as possible. This deformation of space is controlled via a set of control points being placed on a tree dimensional grid. The essential task of finding suitable control point coordinates in the destination color space has been solved with an evolution strategy.
