Many of them are well preserved, but much of their color is highly faded. Thus their today s appearance is very different from the original one. This paper deals with the digital restoration of the appearance of such tapestries. Two methods are developed and examined, one using the back side of the tapestry, the other one using color clustering. Our main criteria are a convincing approximation of the expected appearance and - due to the large size of many of the tapestries - a high degree of automation.Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Image processing and computer vision]: Restoration of tapestries, registration, color clustering
