Title: A prototype calibration target for spectral imaging
Author: Mohammadi, Mahnaz; Nezamabadi, Mahdi; Berns, Roy; Taplin, Lawrence
Abstract: A prototype calibration target was designed and tested for spectral imaging that consisted of 14 samples, nine of which were derived from statistical analyses of artist paints and a five-step grey scale. This target was compared with those commonly used when calibrating spectral-imaging systems. An Esser TE221 scanner target, GretagMacbeth ColorChecker DC, GretagMacbeth ColorChecker Color Rendition Chart, and the prototype target were used as both calibration and verification targets using a modified commercial color-filter-array digital camera as a spectralimaging device. When evaluating a verification target made from 30 different pigments, the prototype target had equivalent performance. Thus for spectral imaging, the spectral properties are more important than the number of samples or its colorimetric range of colors.
