摘要:

基于深度神经网络的目标检测模型已经彻底改变了计算机视觉,并推动了广泛的视觉识别应用的发展。然而,最近的研究表明,在对抗攻击下,深度对象检测器可能会受到损害,导致受害者检测器无法检测到对象、虚假对象或错误标记的对象。随着目标检测在自动驾驶汽车和智慧城市等许多安全关键应用中的广泛应用,我们认为,深入了解深度目标检测系统的对抗攻击和漏洞的整体方法对于研究界开发强大的防御机制至关重要。本文提出了一个框架,用于分析和评估最先进的目标检测器的攻击策略,不利影响和成本,以及跨模型和跨分辨率的可转移性的攻击下的对抗镜头的漏洞,旨在分析和揭秘。使用一组定量指标,对来自三个流行系列(YOLOv 3,SSD和Faster R-CNN)的六个代表性深度目标检测器进行了广泛的实验,其中包括两个基准数据集(PASCAL VOC和MS COCO)。我们证明,所提出的框架可以作为一个有条理的基准分析对抗性的行为和风险的实时目标检测系统。我们推测,这个框架也可以作为一个工具,以评估安全风险和对抗性的鲁棒性的深度对象检测器部署在现实世界中的应用。

英文摘要:

Deep neural networks based object detection models have revolutionized computer vision and fueled the development of a wide range of visual recognition applications. However, recent studies have revealed that deep object detectors can be compromised under adversarial attacks, causing a victim detector to detect no object, fake objects, or mislabeled objects. With object detection being used pervasively in many security-critical applications, such as autonomous vehicles and smart cities, we argue that a holistic approach for an in-depth understanding of adversarial attacks and vulnerabilities of deep object detection systems is of utmost importance for the research community to develop robust defense mechanisms. This paper presents a framework for analyzing and evaluating vulnerabilities of the state-of-the-art object detectors under an adversarial lens, aiming to analyze and demystify the attack strategies, adverse effects, and costs, as well as the cross-model and cross-resolution transferability of attacks. Using a set of quantitative metrics, extensive experiments are performed on six representative deep object detectors from three popular families (YOLOv3, SSD, and Faster R-CNN) with two benchmark datasets (PASCAL VOC and MS COCO). We demonstrate that the proposed framework can serve as a methodical benchmark for analyzing adversarial behaviors and risks in real-time object detection systems. We conjecture that this framework can also serve as a tool to assess the security risks and the adversarial robustness of deep object detectors to be deployed in real-world applications.
