FaceQgen: Semi-Supervised Deep Learning for Face Image Quality Assessment
Javier Hernandez-Ortega, Julian Fierrez, Ignacio Serna +1
In this paper we develop FaceQgen, a No-Reference Quality Assessment approach for face images based on a Generative Adversarial Network that generates a scalar quality measure rela…
Introduction to Presentation Attack Detection in Face Biometrics and Recent Advances
Javier Hernandez-Ortega, Julian Fierrez, Aythami Morales +1
The main scope of this chapter is to serve as an introduction to face presentation attack detection, including key resources and advances in the field in the last few years. The ne…
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…
DeepFakesON-Phys: DeepFakes Detection based on Heart Rate Estimation
Javier Hernandez-Ortega, Ruben Tolosana, Julian Fierrez +1
This work introduces a novel DeepFake detection framework based on physiological measurement. In particular, we consider information related to the heart rate using remote photople…
Biometric Quality: Review and Application to Face Recognition with FaceQnet
Javier Hernandez-Ortega, Javier Galbally, Julian Fierrez +1
"The output of a computerised system can only be as accurate as the information entered into it." This rather trivial statement is the basis behind one of the driving concepts in b…
Heart Rate Estimation from Face Videos for Student Assessment: Experiments on edBB
Javier Hernandez-Ortega, Roberto Daza, Aythami Morales +2
In this study we estimate the heart rate from face videos for student assessment. This information could be very valuable to track their status along time and also to estimate othe…
A Comparative Evaluation of Heart Rate Estimation Methods using Face Videos
Javier Hernandez-Ortega, Julian Fierrez, Aythami Morales +1
This paper presents a comparative evaluation of methods for remote heart rate estimation using face videos, i.e., given a video sequence of the face as input, methods to process it…
edBB: Biometrics and Behavior for Assessing Remote Education
Javier Hernandez-Ortega, Roberto Daza, Aythami Morales +2
We present a platform for student monitoring in remote education consisting of a collection of sensors and software that capture biometric and behavioral data. We define a collecti…
Quality-based Pulse Estimation from NIR Face Video with Application to Driver Monitoring
Javier Hernandez-Ortega, Shigenori Nagae, Julian Fierrez +1
In this paper we develop a robust for heart rate (HR) estimation method using face video for challenging scenarios with high variability sources such as head movement, illumination…
FaceQnet: Quality Assessment for Face Recognition based on Deep Learning
Javier Hernandez-Ortega, Javier Galbally, Julian Fierrez +2
In this paper we develop a Quality Assessment approach for face recognition based on deep learning. The method consists of a Convolutional Neural Network, FaceQnet, that is used to…
