Interest of syntactic knowledge for on-line flowchart recognition
Résumé
In this paper, we address the problem of segmentation and recognition of on-line a posteriori flowcharts. Flowcharts are bi-dimensional documents, in the sense that the order of writing is not de ned. Some statistical approaches have been proposed in the literature to label and segment the flowcharts. However, as they are very well structured documents, we propose to introduce some structural and syntactic knowledge on flowcharts to improve their recognition. For this purpose, we have used an existing grammatical o -line method with on-line a posteriori signal. We apply this work on a freely available database. The results demonstrate the interest of structural knowledge on the context to improve the recognition.
