Unified 3D Instance Segmentation with Contrastive Learning
Analysis
Key Takeaways
- •Proposes UniC-Lift, a unified framework for 3D instance segmentation.
- •Merges contrastive learning and label consistency steps for improved efficiency and performance.
- •Introduces a learnable feature embedding and 'Embedding-to-Label' process.
- •Addresses object boundary artifacts with hard-mining and a stabilizing linear layer.
- •Outperforms baselines on ScanNet, Replica3D, and Messy-Rooms datasets.
