Open-Set: ID Card Presentation Attack Detection using Neural Transfer Style

no code implementations21 Dec 2023 Reuben Markham, Juan M. Espin, Mario Nieto-Hidalgo, Juan E. Tapia

The accurate detection of ID card Presentation Attacks (PA) is becoming increasingly important due to the rising number of online/remote services that require the presentation of digital photographs of ID cards for digital onboarding or authentication.

Fitness-for-Duty Classification using Temporal Sequences of Iris Periocular images

no code implementations24 Apr 2023 Pamela C. Zurita, Daniel P. Benalcazar, Juan E. Tapia

Fitness for Duty (FFD) techniques detects whether a subject is Fit to perform their work safely, which means no reduced alertness condition and security, or if they are Unfit, which means alertness condition reduced by sleepiness or consumption of alcohol and drugs.

Impact of Face Image Quality Estimation on Presentation Attack Detection

no code implementations30 Sep 2022 Carlos Aravena, Diego Pasmino, Juan E. Tapia, Christoph Busch

In this paper, we study the effect of quality assessment methods on filtering bona fide and attack samples, their impact on PAD systems, and how the performance of such systems is improved when training on a filtered (by quality) dataset.
