Abstract:
Document enhancement tools are a valuable help in the study of historic documents. Given proper filter settings, many e ffects that impair the legibility can be evened out (e.g. washed out ink, stained and yellowed paper). However, because of di ffering authors, languages, handwritings, fonts and paper conditions, no single parameter set fi ts all documents. Therefore, the parameters are usually tuned in a time-consuming manual process to every individual document. To simplify this procedure, this paper introduces a classifi er for the legibility of an enhanced historic text document. Experiments on the binarisation of a set of documents from 1938 to 1946 show that the classifi er can be used to automatically derive robust filter settings for a variety of documents.
