IDSplat: Instance-Decomposed 3D Gaussian Splatting for Driving Scenes

ArXi:2511.19235v2 Announce Type: replace Reconstructing dynamic driving scenes is essential for developing autonomous systems through sensor-realistic simulation. Although recent methods achieve high-fidelity reconstructions, they either rely on costly human annotations for object trajectories or use time-varying representations without explicit object-level decomposition, leading to intertwined static and dynamic elements that hinder scene separation.
