The Mechanism and Rejuvenation of Color Fading By Ultraviolet Aging
Virtual restoration of fading painting art has important practical significance and practical value for the study and appreciation of works of Art This paper presents a reconstruction method based on aging experiment and computer graphics technology of color. The paper focus on the pigment color fading rule caused by ultraviolet, and builded the robust multivariate regression model using the chroma information measured under the changed aging time, then established fading point and initial color mapping function based on the distance weighted interval mapping algorithm. The experimental results show that, the color fading model used can better describe the color fading rules, the overall coefficient of determination is 91.9％, the relative error is 1％, and weighted root mean square error is 8.9％. The model can represent the color appearance in diverse aging stagehand and rejuvenate the original appearance.
