In recent years, along with the extraordinary diffusion of the Internet and a growing need for
personal verification in many daily applications, automatic signature verification is being …

The theoretical framework and algorithms of a novel method for the generation of synthetic
on-line signatures are presented. This model-based approach combines the spectral …

Identity verification based on offline handwritten signatures is required in various financial
and administrative domains using paper documents. Commonly, the performance of …

It is often difficult to obtain sufficient signature samples to train up a signature verification
system. An elastic matching method to generate additional samples is proposed to expand …

A novel scheme to generate multiple synthetic samples from a real on-line handwritten
signature is proposed. The algorithm models a transmission channel which introduces a …

Traditional methods of biometric analysis are unable to overcome the limitations of existing
approaches, mainly due to the lack of standards for input data, privacy concerns involving …

Biometric technologies focus on the verification and identification of humans using their
possessed biological (anatomical, physiological and behavioral) properties. This paper …

This brief survey addresses the state-of-the-art techniques of inverse biometrics, which deals
with synthesis of biometric data. It reports on genesis of synthetic biometric, advanced …

The present work proposes a novel probabilistic method to reconstruct a hand shape image
from its template. We analyse the degree of similarity between the reconstructed images and …

Sparse data problems are prominent in applications of offline signature verification. By using
a small number of training samples, the class statistics estimation errors may be significant …
