Paper Abstract

This paper presents a short historical perspective of color reproduction technology, where we are at present, and what challenges lie ahead. Today prevalent color management systems are based on pixel-wise processing of color data represented by 3 channels. We believe this does not adequately reproduce the color experience for the user, and that additional dimensions need to be considered. Three such dimensions are discussed: spectral, spatial, and goniometric. We believe the spectral representation plays an important role in color measurement and modeling; however a spectral image representation is likely not to be a mainstream technology due to the high cost incurred, and modest benefits that are appreciated only in certain niche applications. The incorporation of spatial context is likely to be of significant immediate benefit in commercial color imaging applications. Finally, the use of goniometric information in color reproduction is in its infancy, and bears promise. A brief overview of research efforts in each area is presented.
