Abstract
Abstract: In this paper, we describe a system capable of extracting textual information from images of structured documents. In particular the model and the algorithms we described are used to process forms in which the information fields can not be located only by their position on the page, but can also be identified after locating the corresponding instruction fields. The proposed model is based on attributed relational graphs and performs form registration and location of information fields using algorithms based on the hypothesize-and-verify paradigm. The location of instruction fields is carried out in an holistic way, by using connectionist models.
