Offline signature using Cross validation and Graph matching approach
Dipali Bhole, Amarsinh V. Vidhate, Shrikant Velankar · 2011
Compared to physiologically Base biometric system such as fingerprint, face, palm- vein and retina, behavioral based system such as signature, voice, gait etc. are less popular and many are still in infancy. Signature verification is used for banking transactions. In this paper, we discussed Graph matching based approach for signature verification and cross-validation for same. Database signature is preprocessed in which signature extraction method is used to obtain high resolution for smaller normalization box. In Graph based approach the dissimilarity between two signatures are determined by finding minimum Euclidean distance by Hungarian method. In Cross-validation technique the authenticate the test signature. It is observed that this method gives remarkable reduction in Equal Error Rate (EER).
