CycleMix: A Holistic Strategy for Medical Image Segmentation from Scribble Supervision

This project is developed for our CVPR 2022 paper: CycleMix: A Holistic Strategy for Medical Image Segmentation from Scribble Supervision. Our code is implemented based on the PuzzleMix, but is also applicable to other mixup-based augmentation methods. For more information about CycleMix, please read the following paper:

Datasets

  1. The MSCMR dataset with mask annotations can be downloaded from MSCMRseg.
  2. Our scribble annotations of MSCMRseg have been released in MSCMR_scribbles. Please cite this paper if you use the scribbles for your research.
  3. The scribble-annotated MSCMR dataset used for training could be directly downloaded from MSCMR_dataset.
  4. The ACDC dataset with mask annotations can be downloaded from ACDC and the scribble annotations could be downloaded from ACDC scribbles. Please organize the dataset as the following structure:
XXX_dataset/
  -- TestSet/
      --images/
      --labels/
  -- train/
      --images/
      --labels/
  -- val/
      --images/
      --labels/

Usage

  1. Set the "dataset" parameter in main.py, line 76, to the name of dataset, i.e., "MSCMR_dataset".
  2. Set the "output_dir" in main.py, line 79, as the path to save the checkpoints.
  3. Download the dataset, for example, the MSCMR_dataset. Then, Set the dataset path in /data/mscmr.py, line 110, to your data path where the dataset is located in.
  4. Check your GPU devices and modify the "GPU_ids" parameter in main.py, line 83 and "CUDA_VISIBLE_DEVICES" in run.sh.
  5. Start to train by sh run.sh.
CUDA_LAUNCH_BLOCKING=1 CUDA_VISIBLE_DEVICES=5 nohup python main.py --mixup_alpha 0.5 --graph True --n_labels 3 --eta 0.2 --beta 1.2 --gamma 0.5 --neigh_size 4 --transport True --t_size 4 --t_eps 0.8 &
