Diffusion Models for Imperceptible and Transferable Adversarial Attack

2023 · arXiv (Cornell University)

Many existing adversarial attacks generate $L_p$-norm perturbations on image RGB space. Despite some achievements in transferability and attack success rate, the crafted adversarial examples are easily perceived by human eyes. Towards visual imperceptibility, some recent …

Research on visual differences of exits of different grades of tunnels based on machine learning

2024 · Digital Transportation and Safety

Tunnels are vital in connecting crucial transportation hubs as transportation infrastructure evolves. Variations in tunnel design standards and driving conditions across different levels directly impact driver visual perception and traffic safety. This study employs a …
