ego-data-by-object

Reorganized copy of angkul07/ego-data, split into per-object folders.

What changed

• Source is a flat set of numbered N.mp4 + N.hdf5 pairs.
• All episodes are the same task (basic_pick_place, type reset); only the manipulated object varies.
• Episodes are grouped into one folder per object, parsed from each hdf5 object attribute (color/shape stripped). Original numeric IDs preserved.

Layout

<object>/<id>.mp4     # egocentric RGB clip
<object>/<id>.hdf5    # 3D hand/body transforms, confidences, camera intrinsics, task attrs
manifest.json         # id -> {object, category, has_mp4}
categories.csv        # category -> episode count

Contents

• 4110 episodes, 51 object categories.
• Each hdf5 root attrs include: task, object, llm_objects, llm_verbs, description, llm_description, environment, session_name.
