ALEBk: Feasibility Study of Attention Level Estimation via Blink Detection applied to e-Learning
Roberto Daza, Daniel DeAlcala, Aythami Morales +3
This work presents a feasibility study of remote attention level estimation based on eye blink frequency. We first propose an eye blink detection system based on Convolutional Neur…
OTB-morph: One-Time Biometrics via Morphing applied to Face Templates
Mahdi Ghafourian, Julian Fierrez, Ruben Vera-Rodriguez +2
Cancelable biometrics refers to a group of techniques in which the biometric inputs are transformed intentionally using a key before processing or storage. This transformation is r…
Introduction to Presentation Attack Detection in Iris Biometrics and Recent Advances
Aythami Morales, Julian Fierrez, Javier Galbally +1
Iris recognition technology has attracted an increasing interest in the last decades in which we have witnessed a migration from research laboratories to real world applications. T…
Quality Measures in Biometric Systems
Fernando Alonso-Fernandez, Julian Fierrez, Javier Ortega-Garcia
Biometric technology has been increasingly deployed in the past decade, offering greater security and convenience than traditional methods of personal recognition. Although biometr…
Benchmarking Quality-Dependent and Cost-Sensitive Score-Level Multimodal Biometric Fusion Algorithms
Norman Poh, Thirimachos Bourlai, Josef Kittler +13
Automatically verifying the identity of a person by means of biometrics is an important application in day-to-day activities such as accessing banking services and security control…
A Comparative Study of Fingerprint Image-Quality Estimation Methods
Fernando Alonso-Fernandez, Julian Fierrez, Javier Ortega-Garcia +4
One of the open issues in fingerprint verification is the lack of robustness against image-quality degradation. Poor-quality images result in spurious and missing features, thus de…
FaceQvec: Vector Quality Assessment for Face Biometrics based on ISO Compliance
Javier Hernandez-Ortega, Julian Fierrez, Luis F. Gomez +3
In this paper we develop FaceQvec, a software component for estimating the conformity of facial images with each of the points contemplated in the ISO/IEC 19794-5, a quality standa…
BiosecurID: a multimodal biometric database
Julian Fierrez, Javier Galbally, Javier Ortega-Garcia +22
A new multimodal biometric database, acquired in the framework of the BiosecurID project, is presented together with the description of the acquisition setup and protocol. The data…
Direct attacks using fake images in iris verification
Virginia Ruiz-Albacete, Pedro Tome-Gonzalez, Fernando Alonso-Fernandez +3
In this contribution, the vulnerabilities of iris-based recognition systems to direct attacks are studied. A database of fake iris images has been created from real iris of the Bio…
SetMargin Loss applied to Deep Keystroke Biometrics with Circle Packing Interpretation
Aythami Morales, Julian Fierrez, Alejandro Acien +2
This work presents a new deep learning approach for keystroke biometrics based on a novel Distance Metric Learning method (DML). DML maps input data into a learned representation s…
IFBiD: Inference-Free Bias Detection
Ignacio Serna, Daniel DeAlcala, Aythami Morales +2
This paper is the first to explore an automatic way to detect bias in deep convolutional neural networks by simply looking at their weights. Furthermore, it is also a step towards…
