Medieval manuscript layouts are quite complex. They contain textual elements such as insertions, annotations, and corrections. They may be richly decorated with ornaments, illustrations, and decorative initials making their layout even more complex. In this paper we describe a semi-automatic tool which annotates medieval manuscripts using our generic format. This format allows to represent the physical structure of such manuscripts. Our semi-automatic tool is composed of two parts. The first part achieves a layout analysis which automatically segments manuscripts into text blocks and text lines. That is, a Multi-Layer Perceptron (MLP) identifies layout elements by using color features; it extracts the textual content image of the manuscript. Then, a segmentation based on Connected Component (CC) is performed on the textual content in order to retrieve text blocks and lines. The second part provides an interactive interface allowing the user to customize the automatic analysis, to visualize its results, and to correct them. Our tool is still a prototype, nevertheless, first experiments give encouraging results. Thus, in this paper, we show how to generate a ground truth for medieval manuscripts layouts.

“…Until now, the activities on DL of illuminated manuscripts have been accomplished by manual annotation and indexing, but some interesting systems deserve to be mentioned. The AGORA [25] software performs a map of the foreground and the background and consequently propose a user interface to assist in the creation of an XML annotation of the page components. The Madonne system [24] is another French initiative to use document image analysis techniques for the purpose of preserving and exploiting cultural heritage documents.…”

In this work we propose a system for automatic document segmentation to extract graphical elements from historical manuscripts and then to identify significant pictures from them, removing floral and abstract decorations. The system performs a block based analysis by means of color and texture features. The Gradient Spatial Dependency Matrix, a new texture operator particularly effective for this task, is proposed. The feature vectors are processed by an embedding procedure which allows increased performance in later SVM classification. Results for both feature extraction and embedding based classification are reported, supporting the effectiveness of the proposal.

“…As the visualization assessment made by users is not entirely objective, the evaluation of the perturbation rendering is done with a classifier to evaluate the objective part. We have used a database coming from the digital library BVH [8] which includes 168 printings coming from 42 distinct ornamental letter stamps. The database contains four versions of each ornamental letter stamp, coming from four distinct books.…”

As ancient documents are being digitized, systems for retrieving documents or images can now be found in Digital Libraries. With regard to illustrations, the content-based image retrieval is difficult and the user often needs to check visually the similarity of the retrieved images. This process is not entirely reliable since very similar images (impressions, ornamental letters) can actually be printed from distinct stamps. No other visualization method exists than the map of pixelto-pixel gray level difference (PPDMap). We propose here a method that evaluates locally the differences and allows the user to visualize them. It is based on a local adaptation of the Hausdorff distance. Our method performance is successfully compared to the PPDMap and an expert difference evaluation assesses our method reliability.
