Modern automated surveillance techniques are heavily reliant on deep learning
methods. Despite the superior performance, these learning systems are
inherently vulnerable to adversarial attacks - maliciously crafted inputs that
are designed to mislead, or trick, models into making incorrect predictions. An
adversary can physically change their appearance by wearing adversarial
t-shirts, glasses, or hats or by specific behavior, to potentially avoid
various forms of detection, tracking and recognition of surveillance systems;
and obtain unauthorized access to secure properties and assets. This poses a
severe threat to the security and safety of modern surveillance systems. This
paper reviews recent attempts and findings in learning and designing physical
adversarial attacks for surveillance applications. In particular, we propose a
framework to analyze physical adversarial attacks and provide a comprehensive
survey of physical adversarial attacks on four key surveillance tasks:
detection, identification, tracking, and action recognition under this
framework. Furthermore, we review and analyze strategies to defend against the
physical adversarial attacks and the methods for evaluating the strengths of
the defense. The insights in this paper present an important step in building
resilience within surveillance systems to physical adversarial attacks.

本文回顾了最近在物理对抗攻击方面的尝试和发现，并提出了一种框架来分析物理对抗攻击，并在该框架下对四个关键监控任务：检测，识别，跟踪和动作识别进行了全面的调查。此外，我们还回顾并分析了防御物理对抗攻击的策略和评估防御优势的方法。这篇论文为在监控系统中建立抵抗物理对抗攻击的韧性迈出了重要一步。
