+The repository includes the following components used for the Proxy3D training pipeline:
 - **Training Instructions**: JSON files for stages 1 through 4 (e.g., `stage_4_train_318K.json`).
-- **Embeddings**: Pre-computed vision embeddings for efficiency.
+- **Embeddings**: Pre-computed semantic embeddings for efficiency.
+- **Segmentation masks**: Preprocessed per frame segmentation masks. 
 - **Geometric Data**: Pointmaps and camera poses for 3D reconstruction and scene representation.
