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.
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 55, to the name of dataset, i.e., "MSCMR_dataset".
2. Set the "output_dir" in main.py, line 57, 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 61. Start training with:

python main.py
