GeoPurify: A Data-Efficient Geometric Distillation Framework for Open-Vocabulary 3D Segmentation
The 14th International Conference on Learning Representations (ICLR), 2026
- Diagnosed feature inconsistency when projecting 2D VLM features into 3D.
- Proposed GeoPurify with geometric contrastive distillation to recover latent 3D structure.
- Reached SOTA with only ~1.5% annotated data.
Research Experience
