Spectral Rendering with the Bounded MESE and sRGB Data

Peters, Christoph; Merzbach, Sebastian; Hanika, Johannes; Dachsbacher, Carsten

Abstract (englisch):
In a recent journal paper, we introduced a technique to represent reflectance spectra by an arbitrary number of Fourier coefficients. As a special case, we converted tristimulus data to three Fourier coefficients. After summarizing this work, we introduce the Fourier sRGB color space. It is defined in terms of Fourier coefficients but designed to behave similar to sRGB. Textures stored in Fourier sRGB support efficient spectral rendering but can be compressed with techniques designed for sRGB textures. Compression errors are similar to sRGB.
