# 💎 SAFIRE

Welcome to the official repository for the paper **"SAFIRE: Segment Any Forged Image Region"**, accepted at AAAI 2025.

SAFIRE specializes in image forgery localization through two methods: **binary localization** and **multi-source partitioning**.  
- **Binary localization** identifies the forged regions in an image  by generating a heatmap that visualizes the probability of each pixel being manipulated.
- **Multi-source partitioning** divides the image into segments based on their originating sources. This task is proposed for the first time in this paper.

## 📦️ Training Dataset

We follow the CAT-Net settings for training, which means we used the following datasets:

- **FantasticReality**: The official link is broken. Use: [[Link to Download]](https://github.com/mjkwon2021/CAT-Net/issues/51#issuecomment-2537517937)

- **CASIA**: The official link is broken. Use: [[Link to Download]](https://drive.google.com/drive/folders/13jyChWqg_aKMAxqj-0T2SwSxRrUP7V_X?usp=sharing)
 
- **IMD2020**: Official link: [[Link to Download]](https://staff.utia.cas.cz/novozada/db/)

- **TampCOCO**: Official link: [[Link to Download]](https://www.kaggle.com/datasets/qsii24/tampcoco)

Note that we exclude **CompRAISE** from the original CAT-Net settings.

## ⚙️ Setup

1. **Clone the repository**  
   ```bash
   git clone https://github.com/mjkwon2021/SAFIRE.git
   cd SAFIRE
   ```

2. **Download pre-trained weights**  
   Download the weights from [[Google Drive Link]](https://drive.google.com/drive/folders/1NRxep2G42OnVwCR9sGdf1iPqhCUrGmv2).  
   Place the downloaded weights in the root directory of this repository.

3. **Install dependencies**
   ```bash
   conda env create -f environment.yaml
   conda activate safire
   ```
   For manual installation, run the commands listed in `manual_env_setup.txt`.

## 🚀 Inference

SAFIRE supports two inference types: **binary forgery localization** and **multi-source partitioning**.

1. **Prepare Input Images**  
   - Place your input images in the directory: `ForensicsEval/inputs`.

2. **Output Locations**  
   - Outputs for binary forgery localization will be saved in: `ForensicsEval/outputs_binary`.  
   - Outputs for multi-source partitioning will be saved in: `ForensicsEval/outputs_multi`.

### Binary Forgery Localization
Run the following command:
```bash
python infer_binary.py --resume="safire.pth"
```

### Multi-Source Partitioning
- **Using k-means clustering**:
  ```bash
  python infer_multi.py --resume="safire.pth" --cluster_type="kmeans" --kmeans_cluster_num=3
  ```
- **Using DBSCAN clustering**:
  ```bash
  python infer_multi.py --resume="safire.pth" --cluster_type="dbscan" --dbscan_eps=0.2 --dbscan_min_samples=1
  ```

---
## 🧪 Test

To evaluate the model on your test dataset:

1. **Download the test dataset**  
   Obtain the test dataset and place it in a desired location.

2. **Set the dataset path**  
   Update the dataset path in `ForensicsEval/project_config.py` to point to your downloaded dataset.

3. **Run the evaluation**  
   - For binary prediction:
     ```bash
     python test_binary.py --resume="safire.pth"
     ```
   - For multi-source partitioning:
     ```bash
     python test_multi.py --resume="safire.pth" --cluster_type="kmeans" --kmeans_cluster_num=3
     ```

4. **View Results**  
   The evaluation results will be saved as an Excel file.

## 🔩 Pretrain
We provide support for **distributed data parallel (DDP) pretraining** of the SAFIRE image encoder.
You need `SafireMS-Auto dataset`(See the above Setup section) to pretrain the SAFIRE image encoder.

Run the following command to start pretraining on multiple GPUs with DDP:

```bash
torchrun --nproc-per-node=6 pretrain.py --batch_size=2
````

## 🏗️ Train

We provide support for distributed data parallel (DDP) training using PyTorch. Below are the instructions to train the model using `train.py`:

Run the following command to start training on multiple GPUs with DDP:

```bash
torchrun --nproc-per-node=6 train.py --batch_size=6 --encresume="safire_encoder_pretrained.pth" --resume="" --num_epochs=150
```

Here are the explanations of the flags:
- `--nproc-per-node`: Specifies the number of GPUs to use on a single node.
- `--batch_size`: Sets the batch size per GPU. In this example, the total batch size is (6 * 6 = 36).
- `--encresume`: Specifies the path to the pretrained encoder checkpoint file. It is uploaded to the Google Drive link provided in the Setup section.
- `--resume`: Specifies the path to the model checkpoint file to resume training. Leave empty (`""`) to start training from scratch.
- `--num_epochs`: Sets the total number of training epochs.

Make sure to adjust these parameters and paths in `ForensicsEval/project_config.py`.

## ©️ License

Update (2026-08-05): Working as a researcher in the industry made me realize that strict "research-only" licenses can actually make it quite difficult for corporate researchers to use open-source work, even for pure internal R&D. Because of this, I've decided to relax the licenses for the SAFIRE weights, as well as the SafireMS Dataset series, to CC-BY 4.0. And SAFIRE code to Apache 2.0.

This means you are now free to use them for commercial purposes, provided you give proper attribution.

Please Note: You are still responsible for checking and complying with the copyrights and licenses of any original data used to build the datasets, as well as any third-party code dependencies that SAFIRE relies on. Finally, I (Myung-Joon Kwon) assume no responsibility or liability for any issues arising from the use of the code or data in this repository.
