Abstract

Using reflectance spectra allows to compare the pigment mixtures in paintings. In order to improve the actual subjective spectral comparison, we propose to use spectral similarity measures. The Kullback-Leibler spectral Pseudo-Divergence (KLPD) is selected due to his expected metrological properties. The comparison between a subjective assessment and the objective assessment is developed for mixture of pigments coming from a cultural heritage painting. The obtained results show the good quality of the relationship between the subjective results and the objective ones using the KLPD.
