PatchScene: Patch-based Voxel Diffusion Model for Large-Scale Scene Completion
CVPR 2026
We propose PatchScene, a novel diffusion-based framework for large-scale LiDAR scene completion. Unlike existing methods that rely on global latent representations or dense voxel grids, PatchScene adopts a patch-based voxel diffusion paradigm that explicitly generates fine-grained geometry within lo
