Reflectance spectra of Munsell standard chips and their appearance

Abstract

In this article, we present the results of analysis by two different methods for representing information in reflectance spectra of Munsell standard chips that relates to their appearance.

Popular colour order systems

“…The Scaling perceptual differences δ jk between two Munsell standard chips j and k have shown that chips are embeddable as a confi guration of points ( P j ) in a 3D space locally Euclidean metric. However, in order to accumulate through this approach a tremendous amount of experimentation is necessary to collect suffi cient information that is necessary to provide Munsell colour solid with a unifi ed distance scale (Indow and Romney, 2008).…”

Spectral recovery of outdoor illumination by an extension of the Bayesian inverse approach to the Gaussian mixture model

“…Recent decades have witnessed a growing interest in the analysis of spectral signals applied to spectral compression and reconstruction. Thus, efficient spectral representation and color communication, together with the spectral analysis of solar illuminations and reflectance of colored samples, have been the subject of extensive research [1][2][3][4][5][6][7]. Within this context, the characteristics of the solar radiation spectrum in the ultraviolet, visible, and near-infrared regions is of crucial consideration in many disciplines, particularly in imaging, vision, and color science [8].…”
