#Autonomous Driving #Safety #Simulation #World Models #4D Gaussian Splatting

An agentic workflow that infers crash trajectories from real accident reports, and a pipeline that turns those trajectories into photorealistic 4D Gaussian Splatting scenes.

DC-Forward: Robust FeedForward Reconstruction from In-the-wild Driving-Scene Videos

Bodong Bi*, Nuo Chen*, Zhiwen Fan† Planned submission to CVPR 2027

#4D Gaussian Splatting #Reconstruction #Autonomous Driving

A feedforward 4D Gaussian Splatting reconstruction model for in-the-wild driving-scene videos that predicts patch-level reliability for geometry and appearance, removing foreground-occlusion and reflection artifacts.
