SegAN: Semantic Segmentation with Adversarial Learning

Pytorch implementation for the basic ideas from the paper SegAN: Adversarial Network with Multi-scale L1 Loss for Medical Image Segmentation by Yuan Xue, Tao Xu, Han Zhang, L. Rodney Long, Xiaolei Huang.

The data and architecture are mainly from the paper Adversarial Learning with Multi-Scale Loss for Skin Lesion Segmentation by Yuan Xue, Tao Xu, Xiaolei Huang.

Dependencies

python 2.7

Pytorch 1.2

Data

Training

  • The steps to train a SegAN model on the ISIC skin lesion segmentation dataset.
    • Run with: CUDA_VISIBLE_DEVICES=X(your GPU id) python train.py --cuda. You can change training hyperparameters as you wish, the default output folder is ~/outputs. For now we only support training with one GPU. The training images will be save in the ~/outputs folder.
    • The training code also includes the validation part, we will report validation results every 10 epochs, validation images will also be saved in the ~/outputs folder.
  • If you want to try your own datasets, you can just do whatever preprocess you want for your data to make them have similar format as this skin lesion segmentation dataset and put them in a folder similar to ~/ISIC-2017_Training_Data. You can run the model directly for a natural image dataset; For 3D medical data such as brain MRI scans, you need to extract 2D slices from the original data first. If your dataset has more than one class of label, you can run multiple S1-1C models as we described in the SegAN paper.
