Analysis and Correction of the Joensuu Munsell Glossy Spectral Database

摘要

The spectral reflectances for the Munsell glossy data found in the Joensuu spectral database were analyzed and differences with the Munsell Renotation data were visualized showing discrepancies. Two methods of correcting these differences were explored. The first method attempted to correct for differences in specular exclusion of the measurement devices. The second method of correcting the spectral reflectances resulted in correctly matching the colorimetry defined by the Munsell renotation data set. Additionally, color inconstancy index results were visualized depicting possible aspects of chromatic adaptation as well as the areas where spectral reflectances might be found that better maintain relationships with neighboring colors under different lighting conditions.
