egoCDT — ARCTIC backup (mirrors official v1_0/ layout)

Gated backup of the ARCTIC dataset (MPI-IS), plus the SMPL-X / MANO body models it depends on.

License & access. ARCTIC, SMPL-X and MANO are each distributed under restrictive licenses that require individual registration with MPI. This repo is gated (manual approval); do not remove the gate or otherwise redistribute. Requesters must hold their own ARCTIC / SMPL-X / MANO licenses.

The repo layout mirrors the official release root arctic_release/.../v1_0/, so future downloads of other parts (cropped_images_zips, full-res images_zips, …) can be dropped in at their original relative paths.

Deviation from the original release: the official data/images_zips/<sid>/<seq>.zip files bundle all 10 camera views. This backup keeps only the egocentric view (view folder 0/), re-packed as one uncompressed tar per sequence containing 0/xxxxx.jpg. 339 sequences, 243,743 frames, ~85 GB. All other files above are the original zips, sha256-verified against the official checksum.json at download time (except the three mocap zips and the two body-model zips, which have no published ARCTIC checksum).

• manifest.tsv — per-sequence ego frame count and the sha256 of the original official image zip each tar was extracted from.
