Towards Effective Adversarial Textured 3D Meshes on Physical Face Recognition

CVPR 2023highlight

Face recognition is a prevailing authentication solution in numerous biometric applications. Physical adversarial attacks, as an important surrogate, can identify the weaknesses of face recognition systems and evaluate their robustness before deployed. However, most existing physical attacks are eit…
