VoxAtnNet: A 3D Point Clouds Convolutional Neural Network for Generalizable Face Presentation Attack Detection

no code implementations19 Apr 2024 Raghavendra Ramachandra, Narayan Vetrekar, Sushma Venkatesh, Savita Nageshker, Jag Mohan Singh, R. S. Gad

In this work, we propose a novel Presentation Attack Detection (PAD) algorithm based on 3D point clouds captured using the frontal camera of a smartphone to detect presentation attacks.

Multispectral Imaging for Differential Face Morphing Attack Detection: A Preliminary Study

no code implementations7 Apr 2023 Raghavendra Ramachandra, Sushma Venkatesh, Naser Damer, Narayan Vetrekar, Rajendra Gad

The D-MAD methods are based on using two facial images that are captured from the ePassport (also called the reference image) and the trusted device (for example, Automatic Border Control (ABC) gates) to detect whether the face image presented in ePassport is morphed.
