SynSeg-Net

(End-to-end Synthesis and Segmentation Network)

Adversarial Synthesis Learning Enables Segmentation Without Target Modality Ground Truth

This is our ongoing PyTorch implementation for end-to-end synthesis and segmentation without groudtruth. The paper can be found in arXiv for ISBI 2018 The video can be found in video on youtube

The code was written by Yuankai Huo and developed upon CycleGAN Torch.

Prerequisites

• Linux or macOS
• Python 2
• CPU or NVIDIA GPU + CUDA CuDNN
• pytorch 0.2

Training Data and Testing Data

We used MRI and CT 2D slices (from coronal view) as well as MRI segmentatons as training data. We used CT 2D slices (from coronal view) as testing data The data orgnization can be seen in the txt files in sublist directory

Training

• Train the model

python train_yh.py --dataroot ./datasets/yh --name yh_cyclegan_imgandseg --batchSize 4 --model cycle_seg --pool_size 50 --no_dropout --yh_run_model Train --dataset_mode yh_seg --input_nc 1  --seg_norm CrossEntropy --output_nc 1 --output_nc_seg 7 --checkpoints_dir /home-local/Cycle_Deep/Checkpoints/ --test_seg_output_dir /home-local/Cycle_Deep/Output/  --display_id 0 

• 'name' is --model "cycle_seg" means EssNet --yh_run_model " Train" means do training --output_nv_seg defines number of segmentation labels --checkpoints_dir the place to save checkpoint (model) --test_seg_output_dir the place to save the test segmentation

Testing

• Test the synthesis

python train_yh.py --dataroot ./datasets/yh --name yh_cyclegan_imgandseg --batchSize 4 --model cycle_gan --pool_size 50 --no_dropout --yh_run_model Test --dataset_mode yh --input_nc 1 --output_nc 1 --checkpoints_dir /home-local/Cycle_Deep/Checkpoints/ --test_seg_output_dir /home-local/Cycle_Deep/Output/ --which_epoch 50

• Test the segmentation

python train_yh.py --dataroot ./datasets/yh --name yh_cyclegan_imgandseg --batchSize 4 --model test_seg --pool_size 50 --no_dropout --yh_run_model TestSeg --dataset_mode yh_test_seg  --input_nc 1 --output_nc 1 --checkpoints_dir/home-local/Cycle_Deep/Checkpoints/ --test_seg_output_dir /home-local/Cycle_Deep/Output/ --which_epoch 50

• 'name' is --which_epoch which training epoch to load
