# HOI-DETR — Hand–Object Interaction Detection

Detects hands, 1st-order objects (held), and 2nd-order objects (acted upon),
plus their pairwise interaction links — in a single forward pass.

On each cold start, `app.py` clones
[HOI-DETR](https://github.com/AhmadDarKhalil/HOI-DETR) from GitHub, so any
change pushed to GitHub is reflected automatically on the next Space restart.
