A new paper accepted in CVPR 2024 : "DAP: A Dynamic Adversarial Patch for Evading Person Detectors", You can find it Here
A new paper accepted in CVPR 2023 : "Jedi: Entropy-based Localization and Removal of Adversarial Patches", we propose a Shannon's entropy-based defense against physical adversarial patches. Key findings:
- We establish that adversarial patches have inherently high entropy distribution compared to benign images (including naturalistic patches)
- We leverage this observation to detect, localise and neutralise adversarial patches, recovering initial models performance
- We proposed a new adaptive attack that optimises the patch generation with an entropy budget; The generated patches evade detection BUT are no longer adversarial ... This lose-lose game is in favour of the defender.
