⚙️ Setup

git clone https://github.com/yifliu3/EndoGaussian.git
cd EndoGaussian
git submodule update --init --recursive
conda create -n EndoGaussian python=3.7 
conda activate EndoGaussian

pip install -r requirements.txt
pip install -e submodules/depth-diff-gaussian-rasterization
pip install -e submodules/simple-knn

In our environment, we use pytorch=1.13.1, and the CUDA compile version is 11.7.

📚 Data Preparation

EndoNeRF:
The dataset provided in EndoNeRF is used. You can download and process the dataset from their website (https://github.com/med-air/EndoNeRF). We use the two accessible clips including 'pulling_soft_tissues' and 'cutting_tissues_twice'.

SCARED:
The dataset provided in SCARED is used. To obtain a link to the data and code release, sign the challenge rules and email them to [email protected]. You will receive a temporary link to download the data and code. Follow MICCAI_challenge_preprocess to extract data. The resulted file structure is as follows.

├── data
│   | endonerf 
│     ├── pulling
│     ├── cutting 
│   | scared
│     ├── dataset_1
│       ├── keyframe_1
│           ├── data

⏳ Training

For training scenes such as pulling_soft_tissues, run

python train.py -s data/endonerf/pulling --port 6017 --expname endonerf/pulling --configs arguments/endonerf/pulling.py 

You can customize your training config through the config files.

🎇 Rendering & Reconstruction(optional)

Run the following script to render the images.

python render.py --model_path output/endonerf/pulling  --skip_train --skip_video --configs arguments/endonerf/pulling.py

You can use --skip_train, --skip_test, and --skip_video to skip rendering images of training, testing, and video set. By default, all three sets are rendered.

Besides, we also provide point cloud reconstruction function, you can add extra arguments --reconstruct to activate it.

📏 Evaluation

You can just run the following script to evaluate the model.

python metrics.py --model_path output/endonerf/pulling
