Document representation refinement for precise region description (2014)
Conference Proceeding
Clausner, C., Pletschacher, S., & Antonacopoulos, A. (2014). Document representation refinement for precise region description. In A. Antonacopoulos, & K. Schulz (Eds.), DATeCH '14: Proceedings of the First International Conference on Digital Access to Textual Cultural Heritage. https://doi.org/10.1145/2595188.2595198

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)
Conference Proceeding
Clausner, C., Pletschacher, S., & Antonacopoulos, A. (2013). The significance of reading order in document recognition and its evaluation. In Proceedings of the 2013 12th International Conference on Document Analysis and Recognition. https://doi.org/10.1109/ICDAR.2013.141

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.
