Semi-Supervised learning for Face Anti-Spoofing using Apex frame

Usman Muhammad, Mourad Oussalah, Jorma Laaksonen

Conventional feature extraction techniques in the face anti-spoofing domain either analyze the entire video sequence or focus on a specific segment to improve model performance. Ho…

Domain Generalization via Ensemble Stacking for Face Presentation Attack Detection

Usman Muhammad, Jorma Laaksonen, Djamila Romaissa Beddiar +1

Face Presentation Attack Detection (PAD) plays a pivotal role in securing face recognition systems against spoofing attacks. Although great progress has been made in designing face…

Face Anti-Spoofing from the Perspective of Data Sampling

Usman Muhammad, Mourad Oussalah

Without deploying face anti-spoofing countermeasures, face recognition systems can be spoofed by presenting a printed photo, a video, or a silicon mask of a genuine user. Thus, fac…
