VAST AI Research · Single-Image 3D Scenes

Mira-Scene

Reconstructs an editable 3D scene from a single image through instance segmentation, depth estimation, canonical-coordinate and voxel prediction, object mesh generation, scene assembly and environment-map generation, with resumable multi-stage execution across multiple GPUs. Reports gains over SAM3D using roughly 80,000 training samples and fully automatic annotation against SAM3D's million-plus manually labelled set: Chamfer Distance 0.021 against 0.027, F-Score at 0.1 of 0.843 against 0.817, 3D IoU 0.727 against 0.520. Code and pretrained weights, including a finetuning checkpoint, released.
