A Model-based Signature Verification System

In this work a hybrid handwritten signature verification system architecture is built where the segmentation of the signature is done inspired by a vectorial delta-lognormal kinematic handwritten reproduction model. The acquisition module processes dynamic data sampled from a digitizer tablet creating a prototype signature that is saved in a database with the correspondent feature's thresholds. The verification is done over the image of the test signature without the presence of the author. Details about the segmentation methodology are presented along with the system's architecture and performance results. ©2007 IEEE.Wirtz, B., Average prototypes for stroke-based signature verification (1997) Proceedings of the International Conference on Document Analysis and Recognition, 1, pp. 268-272Privitera, C., Plamondon, R., A System for Scanning and Segmenting Cursively Handwritten Words into Basic Strokes (1995) Proceedings of the International Conference on Document Analysis and Recognition, pp. 1047-1050Brault, H.J.-J., Plamondon, R., Segmenting Handwritten Signatures at Their Perceptually Important Points (1993) IEEE Transactions on PAMI, 15 (9), pp. 953-957O'Gorman, L., An Analysis of Feature Detectability from Curvature Estimation (1988) Proceedings of the Computer Society Conference on Computer Vision and Pattern Recognition, pp. 235-240O'Gorman, L., Curvilinear Feature Detection from Curvature Estimation (1988) Proceedings of the 9th International Conference on Pattern Recognition, pp. 1116-1119Kadirkamanathan, M., Rayner, P.J., A Unified Approach to On-Line Cursive Script Segmentation and Feature Extraction (1989) Proceedings of ICASSP, pp. 1659-1662Plamondon, R., Srihari, S., On-Line and Off-Line Handwriting Recognition: A Comprehensive Survey (2000) IEEE Transactions on PAMI, 22 (1), pp. 63-84Plamondon, R., Guerfali, W., The Generation of Handwriting with Delta-Lognormal Synergies (1998) Biological Cybernetics, 78, pp. 119-132Plamondon, R., Guerfali, W., Why Handwriting Segmentation Can Be Misleading?
