In this paper, we present an application of digital image processing algorithms for the process of fresco restoration. Modern methods for image preprocessing and evaluation such as image registration, image fusion, and image segmentation are applied on images of the fresco, obtained in different modalities (visual and ultraviolet spectra) and at different times. Moreover, local chemical analyzes are taken into account during the image analysis. The robustness of proposed algorithms should be high due to the bad state of the fresco. Achieved results can give to art restorers better insight into the evolution of the fresco aging and in this way a proper conservation method can be chosen. Developed methods are illustrated by generated output images.

Článek prezentuje aplikaci metod digitálního zpracování obrazu v oblasti restaurování uměleckých děl. Jsou zde zapojeny metody pro geometrické narovnání nasnímaných dat, fúze dat a segmentace, použité na multimodálních datech. Dosažené výsledky jsou prezentovány na fresce ze slovenského kostela.
