Abstract

In this paper, we will discuss about what is the most different spectral reflectance in comparison with a reference spectral reflectance under various illuminants. A measure is defined based on an information criterion whose probability is derived using metameric mismatch volume. The solution of the orthogonal spectral reflectance is derived as an optimization problem maximizing the information criterion. Maximizing the information criterion implies that the two information of spectral reflectances are the most different from the view point of information theory. Experimental results of the optimization derive physical shape of the orthogonal spectral reflectance for a given spectral reflectance.
