## [Brief intro](https://github.com/raidionics/AeroPath#brief-intro)

This repository contains the AeroPath dataset described in ["_AeroPath: An airway segmentation benchmark dataset with challenging pathology_"](https://arxiv.org/abs/2311.01138).  A web application was also developed in the study, to enable users to easily test our deep learning model on their own data. The application was developed using [Gradio](https://www.gradio.app) for the frontend and the segmentation is performed using the [Raidionics](https://raidionics.github.io/) backend.

The dataset is made openly available at [Zenodo](https://zenodo.org/records/10069289) and [the Hugging Face Hub](https://huggingface.co/datasets/andreped/AeroPath). Click any of the two hyperlinks to access the dataset.

## [Dataset](https://github.com/raidionics/AeroPath#data) <a href="https://colab.research.google.com/gist/andreped/6070d1d2914a9ce5847d4b3e687188b7/aeropath-load-dataset-example.ipynb" target="_parent"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"/></a>

### [Accessing dataset](https://github.com/raidionics/AeroPath#accessing-dataset)

The dataset contains 27 CTs with corresponding airways and lung annotations. The folder structure is described below.

The easiest way to access the data is through Python with Hugging Face's [datasets](https://pypi.org/project/datasets/) package:
```
from datasets import load_dataset

# downloads data from Zenodo through the Hugging Face hub
# - might take several minutes (~5 minutes in CoLab)
dataset = load_dataset("andreped/AeroPath")
print(dataset)

# list paths of all available patients and corresponding features (ct/airways/lungs)
for d in dataset["test"]:
  print(d)
```

A detailed interactive demo on how to load and work with the data can be seen on CoLab. Click the CoLab badge <a href="https://colab.research.google.com/gist/andreped/6070d1d2914a9ce5847d4b3e687188b7/aeropath-load-dataset-example.ipynb" target="_parent"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"/></a> to see the notebook or alternatively click [here](https://github.com/raidionics/AeroPath/blob/main/notebooks/aeropath-load-dataset-example.ipynb) to see it on GitHub.

## [Development](https://github.com/raidionics/AeroPath#development)

### [Docker](https://github.com/raidionics/AeroPath#docker)

Alternatively, you can deploy the software locally. Note that this is only relevant for development purposes. Simply dockerize the app and run it:

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

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

### [Python](https://github.com/raidionics/AeroPath#python)

It is also possible to run the app locally without Docker. Just setup a virtual environment and run the app.
Note that the current working directory would need to be adjusted based on where `AeroPath` is located on disk.

```
git clone https://github.com/raidionics/AeroPath.git
cd AeroPath/

virtualenv -python3 venv --clear
source venv/bin/activate
pip install -r ./demo/requirements.txt

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

## [Citation](https://github.com/raidionics/AeroPath#citation)

If you found the dataset and/or web application relevant in your research, please cite the following reference:
```
@misc{støverud2023aeropath,

  year={2023},
  eprint={2311.01138},
  archivePrefix={arXiv},
  primaryClass={cs.CV}
}
```

The dataset is hosted at Zenodo, so you should also cite the following:
```

  url          = {https://doi.org/10.5281/zenodo.10069289}
}
```

The web application is using the [Raidionics]() backend, thus, also consider citing:
