Our method utilizes animage-conditioned 3Dscene diffusion model to simultaneously denoise the 3D poses and geometries of all objects within the scene.

However, existing methods assume a reliable and unbiased forecasting environment, which isnot always available inthe wild. Inthis work, we investigate the vulnerability ofspatiotemporal trafficforecasting models andpropose apractical adversarial spatiotemporal attack framework.
