Abstract

This paper presents an application of digital image processing in the historical sciences. it deals with the processing of x-ray recordings of watermark images taken from Middle Ages codices. A sequence of processing steps for image enhancement, geometrical transformations, watermark extraction,a nd binarization is suggested. The watermarks are stored together with alphanumeric information in a database, allowing the historian to retrieve and compare watermarks and to measure parameters of watermarks such as height, length, distance between special points, and radii.
