Unsupervised Bidirectional Cross-Modality Adaptation via Deeply Synergistic Image and Feature Alignment for Medical Image Segmentation
IEEE Transactions on Medical Imaging

Installation

• Install TensorFlow 1.10 and CUDA 9.0
• Clone this repo

git clone https://github.com/cchen-cc/SIFA
cd SIFA

Data Preparation

• Raw data needs to be written into tfrecord format to be decoded by ./data_loader.py. The pre-processed data has been released from our work PnP-AdaNet. The training data can be downloaded here. The testing CT data can be downloaded here. The testing MR data can be downloaded here.
• Put tfrecord data of two domains into corresponding folders under ./data accordingly.
• Run ./create_datalist.py to generate the datalists containing the path of each data.

Train

• Modify paramter values in ./config_param.json
• Run ./main.py to start the training process

Evaluate

• Specify the model path and test file path in ./evaluate.py
• Run ./evaluate.py to start the evaluation.
