Writing Order Recovery in Complex and Long Static Handwriting
Moises Diaz, Gioele Crispo, Antonio Parziale +2
The order in which the trajectory is executed is a powerful source of information for recognizers. However, there is still no general approach for recovering the trajectory of comp…
MDIW-13: a New Multi-Lingual and Multi-Script Database and Benchmark for Script Identification
Miguel A. Ferrer, Abhijit Das, Moises Diaz +3
Script identification plays a vital role in applications that involve handwriting and document analysis within a multi-script and multi-lingual environment. Moreover, it exhibits a…
Investigating the Common Authorship of Signatures by Off-Line Automatic Signature Verification Without the Use of Reference Signatures
Moises Diaz, Miguel A. Ferrer, Soodamani Ramalingam +1
In automatic signature verification, questioned specimens are usually compared with reference signatures. In writer-dependent schemes, a number of reference signatures are required…
A Perspective Analysis of Handwritten Signature Technology
Moises Diaz, Miguel A. Ferrer, Donato Impedovo +3
Handwritten signatures are biometric traits at the center of debate in the scientific community. Over the last 40 years, the interest in signature studies has grown steadily, havin…
Dynamically enhanced static handwriting representation for Parkinson's disease detection
Moises Diaz, Miguel Angel Ferrer, Donato Impedovo +2
Computer aided diagnosis systems can provide non-invasive, low-cost tools to support clinicians. These systems have the potential to assist the diagnosis and monitoring of neurodeg…
Explainable offline automatic signature verifier to support forensic handwriting examiners
Moises Diaz, Miguel A. Ferrer, Gennaro Vessio
Signature verification is a critical task in many applications, including forensic science, legal judgments, and financial markets. However, current signature verification systems…
SM-DTW: Stability Modulated Dynamic Time Warping for signature verification
Antonio Parziale, Moises Diaz, Miguel A. Ferrer +1
Building upon findings in computational model of handwriting learning and execution, we introduce the concept of stability to explain the difference between the actual movements pe…
iDeLog: Iterative Dual Spatial and Kinematic Extraction of Sigma-Lognormal Parameters
Miguel A. Ferrer, Moises Diaz, Cristina Carmona-Duarte +1
The Kinematic Theory of rapid movements and its associated Sigma-Lognormal model have been extensively used in a large variety of applications. While the physical and biological me…
Static and Dynamic Synthesis of Bengali and Devanagari Signatures
Miguel A. Ferrer, Sukalpa Chanda, Moises Diaz +5
Developing an automatic signature verification system is challenging and demands a large number of training samples. This is why synthetic handwriting generation is an emerging top…
Extending the kinematic theory of rapid movements with new primitives
Miguel A. Ferrer, Moises Diaz, Jose J. Quintana +1
The Kinematic Theory of rapid movements, and its associated Sigma-Lognormal, model 2D spatiotemporal trajectories. It is constructed mainly as a temporal overlap of curves between…
Synthesis of 3D on-air signatures with the Sigma-Lognormal model
Miguel A. Ferrer, Moises Diaz, Cristina Carmona-Duarte +2
Signature synthesis is a computation technique that generates artificial specimens which can support decision making in automatic signature verification. A lot of work has been ded…
