Color changing and fading simulation for frescoes based on empirical knowledge from artists

Abstract

Visualizing the color changing and fading process of ancient Chinese wall paintings to tourists and researchers is of great value in both education and preservation. But previously, because empirical knowledge from artists was not introduced, it is infeasible to simulate the color changing and fading in the absence of physical and chemical knowledge of color changing and fading of frescoes. In this paper, however, empirical knowledge from artists is formalized. Since the improved system can reflect knowledge from artists in addition to the previous physical and chemical modeling, the simulation results are faithful to the color aging process of frescoes. In this article, first, the former related works is reviewed. Then, the formalization of empirical knowledge from artists is narrated. After that, the simulation results are shown and discussed. And finally, future research is suggested. © Springer-Verlag Berlin Heidelberg 2006.
