Page Segmentation Based on Steerable Pyramid Features
Mohamed Benjelil, Rémy Mullot, Adel M. Alimi · 2012
Page segmentation and classification is very important in document layout analysis system before it is presented to an OCR system or for any other subsequent processing steps. In this paper, we propose an accurate and suitably designed system for complex documents segmentation. This system is based on steerable pyramid transform. The features extracted from pyramid sub-bands serve to locate and classify regions into text (either machine printed or handwritten) and non-text (images, graphics, drawings or paintings) in some noise-infected, deformed, multilingual, multi-script document images. These documents contain tabular structures, logos, stamps, handwritten script blocks, photos etc. The encouraging and promising results obtained on 1,000 official complex document images data set are presented in this research paper.
