This paper assesses the common authorship of a set of questioned signature images. Our proposal consists in generating as many models as available questioned signatures. Each model is trained with one questioned signature and artificial duplicates worked out from it. The duplication procedure is based on neurocognitive distortions which are inspired from human writing processes. Once the similarity...
Biometric researchers have historically seen signature duplication as a procedure relevant to improving the performance of automatic signature verifiers. Different approaches have been proposed to duplicate dynamic signatures based on the heuristic affine transformation, nonlinear distortion and the kinematic model of the motor system. The literature on static signature duplication is limited and...
