On the measurement of local stability of handwriting: An application to static signature verification

This paper presents a static signature verification system based on a region-oriented strategy. For this purpose, a suitable technique is proposed for the analysis of local stability in static signature and stable regions are selected during the enrollment phase. In the running phase, an unknown specimen is verified through the analysis of the selected regions, on the basis of a well-defined similarity measure. The experimental results, carried out on signatures from the GPDS database, demonstrate the proposed approach.
