Abstract

Image processing plays a fundamental role in the analysis and documentation of artistic, archaeological, and historical works, such as paintings, sculptures, and mosaics, as well as other artifacts. Color management and enhancement are essential tools to reproduce colors, to understand the execution techniques, and to guarantee the conservation status of the artworks. Moreover, color enhancement allows us to improve the quality of diagnostics images and reproduce multispectral data in order to put in evidence past restorations and/or defects. Finally, starting from the digital reproduction of a particular artwork, it is possible to carry out virtual restorations in both two- and/or three-dimensions and to offer a reading of the work itself, possibly close to its original aspect. In this chapter, the most used color management techniques are presented and discussed with reference to real applications. A short review of color perception interpretation in the history of art is also outlined in order to clarify the problems arising in the documentation and knowledge of artistic works. Many examples of applications to books, paintings, sculptures, and mosaics are shown and discussed with particular reference to the present authors’ direct experience.
