Nieinwazyjne badania obiektów zabytkowych oparte na komputerowym przetwarzaniu i analizie obrazu zajmują coraz bardziej znaczącą pozycję pośród znanych do tej pory podobnych badań w innych dziedzinach, jak medycyna, analiza zdjęć satelitarnych, wojskowość czy kontrola jakości w przemyśle. Niniejsza praca przedstawia przegląd literatury dotyczącej poruszanego tematu a także opis badań własnych przeprowadzonych na udostępnionym obiekcie muzealnym. Przedstawione zostało stanowisko do wykonania zdjęcia w świetle widzialnym, zasady poprawnego oświetlenia obiektu oraz przykład zastosowania makrofotografii. Dodatkowo zaprezentowano otrzymane wyniki analizy z wykorzystaniem fluorescencji UV (ultrafiolet) i reflektografii IR (podczerwień) oraz ich interpretację.

Non-invasive inspection of museum objects based on computer image processing and analysis has recently gained a signifying position among other similar methods known so far in medicine, satellite image analysis, military or quality control in the industry. Investigation outside the visible light spectrum is a basic tool to reveal underdrawings as well as to recognize retouching and former restoration marks in the painting. Computer vision will not replace traditional art historical methods of connoisseurship but enhance and extend them. They can rely on visual features that are hard to determine by eye, for instance subtle relationships among the structure of a brushstroke at different scales or colours. This paper provides an overview of the literature and a case study concerning the analysis performed on a given museum object (Fig. 2, with courtesy of the Museum of Bielsko-Biała). The workplace for VIS photography is shown, as well as the schema of proper illumination of a painting (Fig. 3) and an example of use of macrophotography (Fig. 5, craquelure analysis). Additionally, there are presented the results of inspection with use of UV fluorescence (Fig. 7) and IR reflectography (Fig. 8) together with their interpretation.
