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 — 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
