Abstract

Digital image processing is growing to be of great help in the analysis and documentation of our cultural heritage. We demonstrate this by means of a case study on a detail of the Ghent Altarpiece (1432), of which very few digital reproductions exist. The goal of the work described in this paper is to improve readability of the depiction of text in a book occurring on one of the panels. We realize our objective by detecting and digitally removing cracks. Their detection is particularly difficult because of similar color and size properties compared to the letters in the book. We introduce a multiscale morphological approach to detect cracks of different size. Due to the noisy nature of the images, an improved block-based inpainting technique was developed in order to restore the book to its original glory and hopefully help solving a problem that has been troubling art historians for years.
