| # AffHandGen — Affordance-Guided Diffusion Priors |
|
|
| Diffusion prior checkpoints for **"Affordance-Guided Diffusion Prior for 3D Hand |
| Reconstruction"** (arXiv:2510.00506). |
|
|
| The priors generate MANO hand poses conditioned on affordance text descriptions |
| (DistilBERT) and image features (HaMeR ViT), and are used for test-time |
| refinement of 3D hand reconstructions under occlusion. |
|
|
| | File | Trained on | Used for | |
| |---|---|---| |
| | `hog/ckpt_best.pth` | HOGraspNet (S1 train) | Table 1 HOGraspNet rows | |
| | `ho3d/ckpt_best.pth` | HO3D | Table 1 HO3D rows | |
|
|
| Each directory also contains the exact `train.yml` used for training. |
|
|
| ## Usage |
|
|
| See the [code repository](https://github.com/narudesuyo/AffHandGen) — |
| `docs/REPRODUCING.md` describes the full reproduction procedure. Place the |
| checkpoints at: |
|
|
| ``` |
| output/exp/hog/uniaff_cond_20260228_v1/ckpt_best.pth |
| output/exp/ho3d/20260227_v1/ckpt_best.pth |
| ``` |
