The system allows control of variables like water level to create diverse flood scenarios, and a qualitative human study confirmed the generated images show acceptable realism and robustness.", "body_md": "arXiv:2607.15527v1 Announce Type: new\nAbstract: Physical simulations that predict the behavior of urban disasters, such as climate-related flooding, play a crucial role in disaster prevention and the development of anomaly detection models. However, the severe shortage of flood data in real-world environments, combined with the inherent distortions of fisheye lens images, which are used for urban surveillance, has made high-precision simulations challenging. To address this, we propose a new physical simulation system PhysFlood that leverages Diffusion Models to synthesize realistic floods from just a single image captured by a fisheye lens. Our system not only enables simulation from a single image, but also features the ability to freely control and generate diverse flood scenarios by manipulating physically meaningful variables, such as water levels. In our evaluation experiments, we conducted a qualitative human study and demonstrated that the simulation images generated by PhysFlood exhibit both acceptable realism and robustness.", "url": "https://wpnews.pro/news/physics-aware-masked-diffusion-based-flood-simulation-for-urban-fisheye-disaster", "canonical_source": "https://arxiv.org/abs/2607.15527", "published_at": "2026-07-20 04:00:00+00:00", "updated_at": "2026-07-20 13:56:41.681485+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "generative-ai", "computer-vision"], "entities": [], "alternates": {"html": "https://wpnews.pro/news/physics-aware-masked-diffusion-based-flood-simulation-for-urban-fisheye-disaster", "markdown": "https://wpnews.pro/news/physics-aware-masked-diffusion-based-flood-simulation-for-urban-fisheye-disaster.md", "text": "https://wpnews.pro/news/physics-aware-masked-diffusion-based-flood-simulation-for-urban-fisheye-disaster.txt", "jsonld": "https://wpnews.pro/news/physics-aware-masked-diffusion-based-flood-simulation-for-urban-fisheye-disaster.jsonld"}}
