# Weights for *Structure from Duplicates* (SfD)

Pretrained checkpoints used by the SfD preprocessing pipeline
([Tianhang-Cheng/SfD](https://github.com/Tianhang-Cheng/SfD)). They are hosted here instead of in the
git repository to keep clones small.

| file | size | what it is |
| --- | --- | --- |
| `keypoint_matching/superpoint_v1.pth` | 5 MB | SuperPoint detector/descriptor |
| `keypoint_matching/superglue_indoor.pth` | 46 MB | SuperGlue matcher, indoor weights |
| `keypoint_matching/superglue_outdoor.pth` | 46 MB | SuperGlue matcher, outdoor weights |

## Usage

From a clone of the repo, all three land in `preprocess/keypoint_matching/weights/`:

```bash
python download_assets.py --weights
```

The pipeline also fetches them lazily the first time the matcher is constructed, so this step is
optional.

Directly:

```python
from huggingface_hub import hf_hub_download

hf_hub_download("TianhangCheng7/DuplicateWeight", "keypoint_matching/superpoint_v1.pth")
```
