Color Impression Compensation and Sharing Between Observers Based on Subjective Assessments Using Simplicial Maps
Ryo Kamiyama, Jinhui Chao (Chuo Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) Interactive Evolutionary Computation (IEC) has been proposed as a method that enables color compensation by adjusting color transformation parameters based on subjective evaluation. However, because the correspondence between the parameter space and impression space is unknown in IEC, the compensation direction in the impression space is not conveyed to the parameter space, and stochastic optimization, which requires repetition of subjective evaluation, is used. Here we develop a color transformation method that shares impressions among different observers by rigorously modeling the correspondence between the parameter space and impression space using simplicial maps. Specifically, we propose a method that constructs simplicial maps that is a local linear approximation of the nonlinear map between the parameter space and the impression space, and computes the target parameters directly using the inverse map.
