Automatic Handwriting Analysis – From Scribe to Script Type Classification.

Digital libraries, such as Gallica, monasterium.net, or the Vatican’s DigiVatLib, are amassing digitizations of medieval manuscripts. However, those digital copies are often produced without any or only little metadata. This is problematic when trying to actually work scientifically with the data. Enriching the metadata for these collections often requires human experts, making it a time-consuming and expensive task. In this context, methods derived from the field of computer vision are explored to automatically compute missing information such as the script type, the date, or the writer. The talk will start explaining a method for writer recognition based on bag-of-(visual) words. While this method works very good for contemporary data, historical data still poses a challenge, where factors such as decorations or background artifacts might influence a correct assignment. Possibilities to deal with historical data will be shown before proceeding with two other tasks: the classification of medieval Latin script types and the dating of medieval charters.
