Core idea

Overview of PCLMix

Visual result

Dataset

• The ACDC dataset with mask annotations can be downloaded from: ACDC.
• The Scribble annotations of ACDC can be downloaded from: Scribble.

Usage

1. Clone the project.

   git clone https://github.com/Torpedo2648/PCLMix.git
   

2. Train the model.

   python train_contrast.py --exp "PCLMix_contrast" --fold fold1 --contrast_weight 0.1 --het_weight 1.0 --unsup_m_weight 1.0 --tf_decoder_weight 0.4 --gpu 0
   python train_contrast.py --exp "PCLMix_contrast" --fold fold2 --contrast_weight 0.1 --het_weight 1.0 --unsup_m_weight 1.0 --tf_decoder_weight 0.4 --gpu 0
   python train_contrast.py --exp "PCLMix_contrast" --fold fold3 --contrast_weight 0.1 --het_weight 1.0 --unsup_m_weight 1.0 --tf_decoder_weight 0.4 --gpu 0
   python train_contrast.py --exp "PCLMix_contrast" --fold fold4 --contrast_weight 0.1 --het_weight 1.0 --unsup_m_weight 1.0 --tf_decoder_weight 0.4 --gpu 0
   python train_contrast.py --exp "PCLMix_contrast" --fold fold5 --contrast_weight 0.1 --het_weight 1.0 --unsup_m_weight 1.0 --tf_decoder_weight 0.4 --gpu 0
   

3. Test the model.

   python test_cnn.py --exp "PCLMix_contrast" --gpu 0
