Summary

Deep neural network (DNN)-based object detectors, widely used for aerial and satellite imagery analysis, are vulnerable to physical adversarial patch attacks. This research evaluates such attacks against an aerial vehicle detector by optimizing patches digitally to minimize objectness score, incorporating non-printability score (NPS) and total variation (TV) constraints for printability and smoothness. Experiments with a YOLOv3 detector show the OFF patch achieved 85.51% Average Objectness Reduction Rate (AORR) digitally, but the ON patch demonstrated superior physical robustness (0.197-0.343 Objectness Score Ratio (OSR)) due to consistent visibility. Weather-based augmentation did not improve patch optimization. These findings highlight practical vulnerabilities in aerial object detection systems.

Key takeaway

For AI Security Engineers developing or deploying aerial vehicle detection systems, this research indicates that physical adversarial patches are a realistic threat. You should prioritize evaluating the physical robustness of your models, as digital attack effectiveness does not directly translate to real-world vulnerability. Focus on deployment configurations that maintain consistent patch visibility, and consider specific physical attack vectors beyond digital optimization alone.

Key insights

Digital adversarial patches can transfer to physical environments, posing realistic threats to aerial object detection systems.

Principles

• Digital attack effectiveness does not guarantee physical robustness.
• Consistent patch visibility is crucial for physical adversarial attack success.

Method

Adversarial patches are optimized digitally using a loss function that minimizes maximum objectness score, constrained by non-printability score (NPS) and total variation (TV).

In practice

• Deploy patches in ON, OFF, and OFF-Side configurations.
• Evaluate physical robustness using Objectness Score Ratio (OSR).
