# ReImage: Robust Image Self-Recovery against Tampering using Watermark Generation with Pixel Shuffling

Official pretrained weights for **ReImage**, a neural watermarking-based image self-recovery framework that embeds a shuffled version of the target image into itself as a watermark, enabling tamper localization and recovery of the original content.

## Files

| File | Description |
|---|---|
| `models/200000_G.pth` | Network weights at iteration 200k (use this for inference) |
| `training_state/200000.state` | Optimizer/scheduler state at iteration 200k (only needed to resume training) |

## Download

```bash
pip install -U huggingface_hub
hf download Eurong2/ReImage --local-dir ../experiments/invertible_pipeline
```

The repo mirrors the directory layout expected by the test configs (an `experiments/` directory next to the code repository root):

```
../experiments/invertible_pipeline/models/200000_G.pth
../experiments/invertible_pipeline/training_state/200000.state
```

Then run inference following the instructions in the code repository:

```bash
python test2.py -opt options/test/test.yml
```
