Our project addresses this problem in two ways. Firstly, we will create a tool that can identify font groups automatically, i.e. fonts which are similar to each other and thus can be used jointly for training an OCR model (Christlein / Weichselbaumer 2016). Secondly, we will create OCR-models for various font groups. In this way, we hope to significantly improve the recognition rates of OCR for early printed books. In this paper, we will present and discuss first results on automatic font group recognition.
