Official PyTorch implementation of the SPAC "Stochastic Planner-Actor-Critic for Unsupervised Deformable Image Registration", AAAI 2022.

Requirements

• Version

  • python 3.6
  • pytorch 1.4

• Install requirements:

pip install -r requirements.txt

Training

0. The core algorithm is in brain.py, and we build environment in env.py. The agent.py handles the logic of interactions.
1. Modify config.py to set path to data, iterations, and other parameters.
2. To train the model(s) in the paper, run this command:

python main.py

Evaluation

0. Set 'idx' parameter in config.py to choose existing models.
1. To test our model, run:

python test.py
