The signature verification system is always the most sought after biometric verification system. Being a behavioral biometric trait which can be imitated, the researcher faces a challenge in designing such a system to counter intrapersonal and interpersonal variations. This papers presents DWT based Off-line Signature Verification using Angular Features(More)
In this paper we present a system for off-line signature verification. The paper's contributions are: i) Five distances were calculated and evaluated over the signature database, they are: furthest, nearest, template, central and ncentral. Also, a normalization procedure is established to turn each distance scale invariant; ii) These distances are combined(More)
