# Background-removal comparison

Inbox originals from `live.f12.rocks` vs. backends.

## Layout

- `inputs/` — originals from boka inbox
- `outputs/` — results, naming:

```
<stem>__rembg-u2net__no-alpha.png
<stem>__rembg-u2net__alpha.png
<stem>__rembg-default__no-alpha.png
<stem>__rembg-default__alpha.png
<stem>__rembg-birefnet-general__no-alpha.png
<stem>__rembg-birefnet-general__alpha.png
<stem>__withoutbg-open-weights.png
```

- `rembg-default` = `rembg.remove()` without session (library default = u2net)
- `rembg-u2net` = explicit `new_session("u2net")` — expect identical to default
- `withoutbg` open-weights includes matting in-graph (~2GB RAM claimed)

## Re-run

```bash
./run.sh
```

Skips existing non-empty outputs. Models cached in `model-cache/`.
