Document representation refinement for precise region description (2014)
Presentation / Conference Contribution

Precise description of layout entities (content regions on a page) is crucial for all but the most trivial document analysis and recognition applications. The output of layout analysis methods and state-of-the-art OCR systems varies significantly, fr... Read More about Document representation refinement for precise region description.

The significance of reading order in document recognition and its evaluation (2013)
Presentation / Conference Contribution

Reading order detection and representation is an important task in many digitisation scenarios involving the preservation of the logical structure of a document. The corresponding need for the evaluation of reading order results generated by layout a... Read More about The significance of reading order in document recognition and its evaluation.

Aletheia - An advanced document layout and text ground-truthing system for production environments (2011)
Presentation / Conference Contribution

Large-scale digitisation has led to a number of new possibilities with regard to adaptive and learning based methods in the field of Document Image Analysis and OCR. For ground truth production of large corpora, however, there is still a gap in terms...

Semantics-enriched workflow creation and management system with an application to document image analysis and recognition
Thesis

Scientific workflow systems are an established means to model and execute experiments or processing pipelines. Nevertheless, designing workflows can be a daunting task for users due to the complexities of the systems and the sheer number of available...
