PatchGuard-Freq: Zero-Overhead Adversarial Patch Defense via Frequency Detection and Data-Driven Robustness

Adversarial patch attacks pose a tangible physical-world threat to traffic sign recognition in autonomous driving systems. Current state-of-the-art defenses based on image reconstruction require dual-model deployment and add per-frame inference latency, making them impractical for resource-constrained embedded platform...
