Face spoofing detection based on colour distortions

IET Biometrics, 2017
Securing face recognition systems against spoofing attacks have been recognised as a real challenge. Spoofing attacks are conducted by printing or displaying a digital acquisition of a capture subject (target user) in front of the sensor. These extra reproduction stages generate colour distortions between face artefacts and real faces.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, Volume 43, Issue 3, Page 2254-2341, May 2026.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Deep Anomaly Detection for Generalized Face Anti-Spoofing [PDF]

2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2019
Face recognition has achieved unprecedented results, surpassing human capabilities in certain scenarios. However, these automatic solutions are not ready for production because they can be easily fooled by simple identity impersonation attacks. And although much effort has been devoted to develop face anti-spoofing models, their generalization capacity

Ruthenium Nanoparticle‐On‐Cavity Refractory Thermoplasmonics for Broadband and Spectral‐Selective Solar Photothermal Conversion

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
We identify ruthenium as a refractory plasmonic material exhibiting dual ENZ optical topological transitions and dual plasmonic resonances spanning from visible to infrared region with high imaginary permittivity. We establish a nanoparticle‐on‐cavity (NPoC) resonance mode and realize a NPoC selective solar absorber using cost‐effective additive ...
