Layout-Based Document-Retrieval System by Radon Transform Using Dynamic Time Warping

Abstract: In the context of sustainability of document management technologies, this paper presents a new system for layout-based document retrieval specifically designed for commercial form retrieval. The system first uses a technique based on mathematical morphology to extract grid-based structural components from the document image. Successively, Radon Transform is used for document layout description. A document matching technique based on dynamic time warping is finally adopted. The experimental results carried out on real and simulated data set, demonstrate the effectiveness of the approach with respect to different classes of commercial forms.

Keywords: document management, document image retrieval, sustainability, mathematic morphology, radon transform, dynamic time warping
