We Can Always Catch You: Detecting Adversarial Patched Objects WITH or WITHOUT Signature

Understand

Recently, object detection has proven vulnerable to adversarial patch attacks.

• The attackers holding a specially crafted patch can hide themselves from state-of-the-art detectors, e.g., YOLO, even in the physical world.
• This attack can bring serious security threats, such as escaping from surveillance cameras.
• How to effectively detect this kind of adversarial examples to catch potential attacks has become an important problem.
