**DDMR** was developed by SINTEF Health Research. The corresponding manuscript describing the framework has been published in [PLOS ONE](https://journals.plos.org/plosone/) and the manuscript is openly available [here](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0282110).

## 💻 Getting started

1. Setup virtual environment:
```
virtualenv -ppython3 venv --clear
source venv/bin/activate
```

2. Install requirements:
```
pip install git+https://github.com/jpdefrutos/DDMR
```

## 🤖 How to use
Use the following CLI command to register images
```
ddmr --fixed path/to/fixed_image.nii.gz --moving path/to/moving_image.nii.gz --outputdir path/to/output/dir -a <anatomy> --model <model> --gpu <gpu-number> --original-resolution
```
where:
* anatomy: is the type of anatomy you want to register: B (brain) or L (liver)
* model: is the model you want to use:
    + BL-N (baseline with NCC)
    + BL-NS (baseline with NCC and SSIM)
    + SG-ND (segmentation guided with NCC and DSC)
    + SG-NSD (segmentation guided with NCC, SSIM, and DSC)
    + UW-NSD (uncertainty weighted with NCC, SSIM, and DSC)
    + UW-NSDH (uncertainty weighted with NCC, SSIM, DSC, and HD).
* gpu: is the GPU number you want to the model to run on, if you have multiple and want to use only one GPU
* original-resolution: (flag) whether to upsample the registered image to the fixed image resolution (disabled if the flag is not present)

Use ```ddmr --help``` to see additional options like using precomputed segmentations to crop the images to the desired ROI, or debugging.

## 🤗 Demo  <a target="_blank" href="https://huggingface.co/spaces/andreped/DDMR"><img src="https://img.shields.io/badge/🤗%20Hugging%20Face-Spaces-yellow.svg"></a>

A live demo to easily test the best performing pretrained models was developed in Gradio and is deployed on `Hugging Face`.

To access the live demo, click on the `Hugging Face` badge above. Below is a snapshot of the current state of the demo app.

### Development</summary>

To develop the Gradio app locally, you can use either Python or Docker.

#### Python

You can run the app locally by:

```
python demo/app.py --cwd ./ --share 0
```

Then open `http://127.0.0.1:7860` in your favourite internet browser to view the demo.

#### Docker

Alternatively, you can use docker:

```
docker build -t ddmr .
docker run -it -p 7860:7860 ddmr
```

Then open `http://127.0.0.1:7860` in your favourite internet browser to view the demo.

## 🏋️‍♂️ Training

Use the "MultiTrain" scripts to launch the trainings, providing the neccesary parameters. Those in the COMET folder accepts a `.ini` configuration file (see `COMET/train_config_files/` for example configurations).

For instance:
```
python TrainingScripts/Train_3d.py
```

## 🔍 Evaluate

Use Evaluate_network to test the trained models. On the Brain folder, use `Evaluate_network__test_fixed.py` instead.

For instance:
```
python EvaluationScripts/evaluation.py
```
