Paper Abstract

Previous work on color reproduction has shown that all existing solutions perform in ways that are image dependent. A series of experiments has therefore been carried out to systematically study the influence of a range of image characteristics on color reproduction and it was previously shown that neither image gamuts nor one-dimensional color histograms play an important role. The aim of the present paper then is to investigate whether the 3D histogram of image's colors is an image characteristic that significantly influences the performance of gamut mapping algorithms (GMAs). As this is done with the help of sets of artificial images, where each member of the set has different content but the same 3D color histogram, their use in studying color reproduction is also discussed in this paper. The results of a psychophysical experiment evaluating the influence of 3D color histograms on color reproduction are presented and analyzed in detail. These results show clearly that a significant proportion (approximately 2/3 to 3/4) of the variation in GMA performance caused by differences in image characteristics is due to 3D color histograms.
