LiDAR Resolution Recovery via Foundation-Model-Guided Diffusion
Samed Doğan, Nico Leuze, Alfred Schöttl
High-beam-count LiDAR sensors are costly, yet many perception pipelines require dense angular sampling. Using a pretrained Stable Diffusion model as the backbone, we fine-tune a Li…

Geometry Without Coordinates: LiDAR Diffusion as a 3D Feature Bridge
Samed Doğan, Nico Leuze, Alfred Schöttl
Transferring the rich priors of large 2D foundation models to sparse 3D LiDAR remains challenging, as training native 3D foundation models at comparable scale is limited by data an…
