Synthesis of 3D on-air signatures with the Sigma-Lognormal model

no code implementations29 Jan 2024 Miguel A. Ferrer, Moises Diaz, Cristina Carmona-Duarte, Jose J. Quintana Hernandez, Rejean Plamondon

Addressing the usual cases involving the development of artificial individuals and duplicated samples, this paper contributes to the synthesis of: (1) the trajectory and velocity of entirely 3D new signatures; (2) kinematic information when only the 3D trajectory of the signature is known, and (3) duplicate samples of 3D real signatures.

Extending the kinematic theory of rapid movements with new primitives

no code implementations29 Jan 2024 Miguel A. Ferrer, Moises Diaz, Jose J. Quintana, Cristina Carmona-Duarte

It is constructed mainly as a temporal overlap of curves between virtual target points.

iDeLog: Iterative Dual Spatial and Kinematic Extraction of Sigma-Lognormal Parameters

no code implementations27 Jan 2024 Miguel A. Ferrer, Moises Diaz, Cristina Carmona-Duarte, Rejean Plamondon

The first one, influenced by the motor equivalence model, separately derives an initial action plan defined by a set of virtual points and angles from the trajectory and a sequence of lognormals from the velocity.

Temporal evolution in synthetic handwriting

no code implementations27 Jan 2024 Cristina Carmona-Duarte, Miguel A. Ferrer, Antonio Parziale, Angelo Marcelli

New methods for generating synthetic handwriting images for biometric applications have recently been developed.

Towards Stroke Patients' Upper-limb Automatic Motor Assessment Using Smartwatches

no code implementations9 Dec 2022 Asma Bensalah, Jialuo Chen, Alicia Fornés, Cristina Carmona-Duarte, Josep Lladós, Miguel A. Ferrer

Assessing the physical condition in rehabilitation scenarios is a challenging problem, since it involves Human Activity Recognition (HAR) and kinematic analysis methods.

BeCAPTCHA-Type: Biometric Keystroke Data Generation for Improved Bot Detection

no code implementations27 Jul 2022 Daniel DeAlcala, Aythami Morales, Ruben Tolosana, Alejandro Acien, Julian Fierrez, Santiago Hernandez, Miguel A. Ferrer, Moises Diaz

Different bot detectors are considered based on several supervised classifiers (Support Vector Machine, Random Forest, Gaussian Naive Bayes and a Long Short-Term Memory network) and a learning framework including human and synthetic samples.
