论文摘要
最近,通过将不可察觉的扰动注入视频帧,对对象跟踪已应用于欺骗深层跟踪器。但是,以前的工作仅生成特定于视频的扰动,这限制了其应用程序方案。此外,由于跟踪的实时和重新定位机制,现有攻击在现实中很难实现。为了解决这些问题,我们提出了一种脱机通用对抗攻击,称为有效的通用洗牌攻击。在所有视频中导致跟踪器故障仅需一个扰动。为了提高计算效率和攻击性能,我们提出了一种贪婪的梯度策略和三重损失,以通过梯度有效地捕获和攻击模型特异性特征表示。实验结果表明,EUSA可以显着降低OTB2015和Dot2018上最先进的跟踪器的性能。
Recently, adversarial attacks have been applied in visual object tracking to deceive deep trackers by injecting imperceptible perturbations into video frames. However, previous work only generates the video-specific perturbations, which restricts its application scenarios. In addition, existing attacks are difficult to implement in reality due to the real-time of tracking and the re-initialization mechanism. To address these issues, we propose an offline universal adversarial attack called Efficient Universal Shuffle Attack. It takes only one perturbation to cause the tracker malfunction on all videos. To improve the computational efficiency and attack performance, we propose a greedy gradient strategy and a triple loss to efficiently capture and attack model-specific feature representations through the gradients. Experimental results show that EUSA can significantly reduce the performance of state-of-the-art trackers on OTB2015 and VOT2018.
