Abstract
We propose a chromatic diversity index based on the Munsell set capable of predicting illuminant induced changes in chromatic diversity of complex scenes. The color differences between complex scenes derived from hyperspectral data under a test and under a reference CIE D65 illuminant were computed and compared with the corresponding differences for the Munsell set. It was found that the average color difference between the complex scenes correlates well with the color differences of the Munsell samples with an average correlation of about 0.94, a result indicating that the Munsell set can be used to predict chromatic changes in complex scenes.
