| # PhySIC evaluation release |
|
|
| Per-frame predictions of [PhySIC](https://github.com/YuxuanSnow/Phy-SIC) |
| (SIGGRAPH Asia 2025, [arXiv](https://arxiv.org/abs/2510.11649)) on |
| **PROX-quantitative** (178 frames) and **RICH** (100 frames), with the |
| reconstructed scene each one was optimised against. They reproduce the paper's |
| Table 2 with the evaluation code in the repository's |
| [`eval_release/`](https://github.com/YuxuanSnow/Phy-SIC/tree/main/eval_release), |
| which downloads this data on first run. |
|
|
| ## What is here |
|
|
| ``` |
| release_data/prox/<recording>/<frame>.npz compact tier, 15 MB |
| release_data/rich/<frame>.npz 9.8 MB |
| release_data_full/prox/<recording>/<frame>.npz full scene clouds, 7.6 GB |
| release_data_full/rich/<frame>.npz 5.6 GB |
| ``` |
|
|
| Both tiers hold the same predictions and give identical numbers. The compact |
| tier keeps the scene points the contact metric can reach (~3.6k per PROX frame, |
| ~4.5k per RICH frame); the full tier is the complete reconstructed cloud |
| (~2.0M / ~2.6M points, floor plane included). |
|
|
| ## Per-frame fields |
|
|
| | field | what it is | |
| |---|---| |
| | `init_*`, `final_*` | SMPL-X parameters (betas + 6D rotations) and camera translation, before and after scene-aware optimisation | |
| | `K` | predicted pinhole intrinsics | |
| | `contact_deco` | the image-based contact prediction the optimiser was given | |
| | `scene_points`, `scene_normals` | reconstructed scene, metric scale, camera frame | |
| | `visibility_mask` | body vertices projecting into the segmented person (PROX only) | |
| | `contact_pred_reference` | contact mask as computed by the pipeline, re-derived and checked by the evaluation | |
|
|
| No dataset imagery, depth maps, meshes or ground truth are included. Ground |
| truth comes from your own downloads of [PROX](https://prox.is.tue.mpg.de) and |
| [RICH](https://rich.is.tue.mpg.de), and the bodies use |
| [SMPL-X](https://smpl-x.is.tue.mpg.de), each under its own licence. |
