Abstract

The aim of this work is analyzing the colour measurements performed using a colorimetric imaging system, with three acquisition channels, and a multispectral imaging system, with seven acquisition channels, in terms of the colour ranges measured, i.e. sets of colour samples grouped by their hue property, in order to determine if both the colorimetric and the multispectral imaging systems are especially sensitive to some hues and/or some other colour properties.General tendencies of system's performance in terms of CIELAB coordinates have been analyzed using the GretagMacbeth ColorChecker DC chart (CCDC). System's performance was also analyzed with respect mainly of Munsell hue coordinate using the 1269 colour patches of the Munsell Book of Color – Matte Collection.Similar results were obtained for both configurations using the GretagMacbeth ColorChecker DC chart as training and test sets, but outstandingly different results between both configurations were obtained using the Munsell colour patches grouped in hues and sub-hues, as training and test sets. The multispectral imaging system resulted to be very sensitive to hue homogeneity and the greater uniformity in hue the better results obtained. Moreover, performance of colour measurements for the multispectral imaging system seemed to depend mainly on the hue property of colour samples composing the training and test sets, but not on other colour properties such those represented by the Munsell value V and chroma C coordinates.
