|
|
| Every file has a unique zero-padded 5-digit ID; names follow |
| `tier-category-action-subject`. |
|
|
| > Cleanup before upload: remove the stray `...catwalk-NA.mnm` and |
| > `...hiphop-combo3-umeda.db` (a marker-name-map and a Thumbs.db-type file). |

| ## Usage |
|
|
| ```python |
| from datasets import load_dataset |
| from huggingface_hub import hf_hub_download |
| |
| index = load_dataset("eyesjapan/eyesjapan-mocap", split="train") |
| walks = index.filter(lambda x: x["category"] == "walk" and "bvh" in x["formats"]) |
| |
| path = hf_hub_download( |
| repo_id="eyesjapan/eyesjapan-mocap", repo_type="dataset", |
| filename="data/free/accident/free-accident-dodge-azumi/00004-free-accident-dodge-azumi.bvh", |
| ) |
| ``` |
|
|
| ## Data collection & consent |
|
|
| <!-- TODO: capture hardware/software, studio, subject recruitment. Reference |
| videos show identifiable performers — confirm all subjects consented to public |
| research release, or exclude the .mov/.m4v files. --> |
