Unsupervised method to generate page templates
Hervé Déjean · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2010
In this paper, we propose a method for automatically inferring the different page templates used to layout the document content. The first step of the method consists in performing a logical analysis of the document. Depending of the coverage of this step, a given number of document elements will be labeled. Then geometric relations are computed between these labeled elements, and page templates candidates are generated using frequent related elements. A fuzzy matching operation allows for selecting the most frequent and relevant page templates for a given document. Such page templates can be used to correct errors produced during the different previous steps of the document analysis: zoning, OCR, and logical analysis. Evaluation has been performed using the INEX book track collection.
