ViTransPAD: Video Transformer using convolution and self-attention for Face Presentation Attack Detection

no code implementations3 Mar 2022 Zuheng Ming, Zitong Yu, Musab Al-Ghadi, Muriel Visani, Muhammad MuzzamilLuqman, Jean-Christophe Burie

Instead of using coarse image patches with single-scale as in ViT, we propose the Multi-scale Multi-Head Self-Attention (MsMHSA) architecture to accommodate multi-scale patch partitions of Q, K, V feature maps to the heads of transformer in a coarse-to-fine manner, which enables to learn a fine-grained representation to perform pixel-level discrimination for face PAD.

Predicting Brain Degeneration with a Multimodal Siamese Neural Network

no code implementations2 Nov 2020 Cecilia Ostertag, Marie Beurton-Aimar, Muriel Visani, Thierry Urruty, Karell Bertet

We also show the superiority of the multimodal architecture, for up to 37. 5\% of missing values in test set subjects' clinical measurements, compared to a model using only the clinical modality.

A Survey On Anti-Spoofing Methods For Face Recognition with RGB Cameras of Generic Consumer Devices

no code implementations8 Oct 2020 Zuheng Ming, Muriel Visani, Muhammad Muzzamil Luqman, Jean-Christophe Burie

The widespread deployment of face recognition-based biometric systems has made face Presentation Attack Detection (face anti-spoofing) an increasingly critical issue.
