SlowTrack: Increasing the Latency of Camera-based Perception in Autonomous Driving Using Adversarial Examples

no code implementations15 Dec 2023 Chen Ma, Ningfei Wang, Qi Alfred Chen, Chao Shen

Our evaluation results show that the system-level effects can be significantly improved, i. e., the vehicle crash rate of SlowTrack is around 95% on average while existing works only have around 30%.

Intriguing Properties of Diffusion Models: A Large-Scale Dataset for Evaluating Natural Attack Capability in Text-to-Image Generative Models

no code implementations30 Aug 2023 Takami Sato, Justin Yue, Nanze Chen, Ningfei Wang, Qi Alfred Chen

Motivated by the finding, we construct a large-scale dataset, Natural Denoising Diffusion Attack (NDDA) dataset, to systematically evaluate the risk of the natural attack capability of diffusion models with state-of-the-art text-to-image diffusion models.

Does Physical Adversarial Example Really Matter to Autonomous Driving? Towards System-Level Effect of Adversarial Object Evasion Attack

no code implementations ICCV 2023 Ningfei Wang, Yunpeng Luo, Takami Sato, Kaidi Xu, Qi Alfred Chen

In this work, we conduct the first measurement study on whether and how effectively the existing designs can lead to system-level effects, especially for the STOP sign-evasion attacks due to their popularity and severity.
