abstract (eng):

Spatial alignment of visible and ultraviolet images of microscopic cross-sections from old artworks is solved by means of mutual information. In the next step, preliminary layer segmentation is applied. In the final part, method for content-based image retrieval is described using cooccurence matrices. The aim is to facilitate search for restorers reports about artworks with similar characteristic, based on corss-section images.

Prostorove sesazeni obrazku mikroskopickych rezu starych umeleckych del, porizenych ve viditelnem a ultrafialovem spektru, je reseno pomoci registracni metody "mutual information". V dalsim kroku je vyhotovena prvotni detekce jednotlivych vrstev. Na zaver je popsana metoda pro vyhledavani v databazi na zaklade obrazove informace pomoci kookurencnich matic. Hlavni snahou bylo nabidnout restauratorum snadnejsi vyhledani restauratorskych zprav s podobnou tematikou na zaklade rezu.
