Line separators are used to segregate text-lines from one another in document image analysis. Finding the separator points at every line terminal in a document image would enable text-line segmentation. In particular, identifying the separators in handwritten text could be a thrilling exercise. Obviously it would be challenging to perform this in the compressed version of a document image and t...

Acknowledgements The research reported on in this thesis was based on work in two projects: the DFG-project Deutsches Referenzkorpus, a joint project of the Institut für Maschinelle Sprachverarbeitung (IMS) in Stuttgart, the Seminar für Sprach-wissenschaft (SfS) in Tübingen, and the Institut für deutsche Sprache (IDS) in Mannheim, and the DFG-Transferbereich project Automatische Exzerption whic...

In this paper, we present a new approach to extracting the target text line from a document image captured by a pen scanner. Given the binary image, a set of possible text lines are first formed by nearest-neighbor grouping of connected components (CC). They are then refined by text line merging and adding the missed CCs. The possible target text line is identified by using a geometric feature ...

can be interpreted as matching of an input graph (keyword) with a large set of graphs (document). More formally, in order to spot a certain keyword wi, all p graph instances gi1, ... , gip of that word wi occurring in the training set are matched against all graph words in each text line using our adapted graph matching procedure. That is, for a given word wi and a specific text line s pairwise...
