Vincent Christlein (Nuremberg): Writer identification in historical document images
In the age of mass digitization of historical documents, automatic or semi-automatic procedures for processing and analysing them have a high priority. For example, an automatic image retrieval system based on an image in question may help humanities scholars to retrieve similar images. In contrast to general image retrieval, where the full image is of importance, in writer identification, we commonly focus only on the handwriting. While writer identification/retrieval in clean benchmark data is very successful, reaching identification rates beyond 95 percent even in multi-script scenarios, it becomes increasingly more difficult in historical data. Historical document images often suffer from artifacts, such as rips, holes or water sparkles. To limit their effect, robust methods are needed. We investigate different methods on different algorithmic stages how to improve writer identification for historical documents and show evaluation results of different datasets, such as a dataset of letters and a dataset of papyrus fragments.
