| Pseudocode | Yes | Algorithm 1 Iterative optimization of object segmentation and scene flow estimation. Assume the whole train split has S point cloud pairs: {(P t, P t+1)1 (P t, P t+1)S}. |
| Open Source Code | Yes | Our code and data are available at https://github.com/v LAR-group/OGC |
| Open Datasets | Yes | Our code and data are available at https://github.com/v LAR-group/OGC |
| Dataset Splits | Yes | In total, we create 3750, 250, and 1000 indoor rooms (scenes) for training/validation/test splits. |
| Hardware Specification | Yes | The scene flow network is trained for 200 epochs... using a single NVIDIA A100 GPU. |
| Software Dependencies | Yes | Our code is written in Python 3.8 and PyTorch 1.9. |
| Experiment Setup | Yes | We train the object segmentation network for 100 epochs, with Adam optimizer (β1=0.9, β2=0.999), an initial learning rate of 0.001 and batch size of 8. The scene flow network is trained for 200 epochs with Adam optimizer, an initial learning rate of 0.001 and batch size of 4. |
