Medieval manuscript layout model

Medieval manuscript layouts are quite complex. Additionally to their main text flow, which can spread over one or several columns, such manuscripts contain also other textual elements such as insertions, annotations, and corrections. They are often richly decorated with ornaments, illustrations, and drop capitals making their layout even more complex. In this paper we propose a generic layout model to represent their physical structure. To achieve this goal we propose to use four layers in order to distinguish between the different graphical elements. In this paper we show how this model is used to represent automatic segmentation results and how it allows a quantitative measure of their accuracy.
