Notes
The official readme reports 11,102 images from 261 participants and 522 irises. The site states that UBIRIS.v1 is public and that newer UBIPr derivatives use CC BY-NC-SA 4.0, but it does not make the same license statement for UBIRIS.v2; terms are therefore unknown.
Access information and download
- CLI
- Python
# This route requires upstream human action; no transfer starts.
eyehub download ubiris_v2 --data-dir ./data --dry-run --json
# Follow the official instructions shown by preflight.
from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY
ds = REGISTRY.get_dataset('ubiris_v2')
print(preflight_dataset(ds, './data')) # returns manual_access_blocked
