Analysis and interpretation of visual saliency for document functional labeling
Résumé
In this paper we propose a complete methodology
of printed text characterization for document labeling
using texture features that have been inspired by
a psychovisual approach. This approach considers visual
human-based predicates to describe and identify text
units according to their visual saliency and their perceptual
attraction power on the reader’s eye. It supports
a quick and robust process of functional labeling used
to characterize text regions of document pages. The test
databases are the Finland MTDB Oulu base1 that provides
a great panel of document layouts and contents
and our laboratory corpus that contains a large variety
of composite documents (about 200 pages). The performance
of the method gives very promising results.
