by Yicheng Wu*, Zhonghua Wu, Qianyi Wu, Zongyuan Ge, and Jianfei Cai.

News

<12.06.2022> We provided our pre-trained models on the LA and ACDC datasets, see './SS-Net/pretrained_pth';

<09.06.2022> We released the codes;

Introduction

This repository is for our MICCAI 2022 paper: 'Exploring Smoothness and Class-Separation for Semi-supervised Medical Image Segmentation'.

Requirements

This repository is based on PyTorch 1.8.0, CUDA 11.1 and Python 3.8.10. All experiments in our paper were conducted on a single NVIDIA Tesla V100 GPU with an identical experimental setting.

Usage

  1. Clone the repo.;
git clone https://github.com/ycwu1997/SS-Net.git

  1. Put the data in './SS-Net/data';

  2. Train the model;

cd SS-Net
# e.g., for 5% labels on LA
python ./code/train_ss_3d.py --labelnum 4 --gpu 0
  1. Test the model;
cd SS-Net
# e.g., for 5% labels on LA
python ./code/test_LA.py --labelnum 4
