1. Linux (Titan RTX)
2. Python (3.6.6)
3. torch (1.9.0+cu111)
4. visdom (0.1.8.9)
5. numpy (1.19.2)
6. skimage (0.15.0)
7. Yaml (5.4.1)
8. cv2 (3.4.2)
9. PIL (8.3.2)

1. Create dataset
   • train path/A/
   • train path/B/
   • val path/A/
   • val path/B/
2. The default data file form is .npy and normalized to [-1,1].
3. Modify the parameters in the .yaml file as needed:
   • bidirect: whether to use bidirectional network, corresponding to the C or NC mode in the paper.
   • regist: whether the registration network is used, corresponding to the +R mode in the paper.
   • noise_level: set to 0 if you do not want to use noise.
   • port: port parameters of visdom.
4. Default RegGAN mode (bidirect:False regist:True).
5. Start visdom：

python -m visdom.server -p 6019

If other port parameters are used, you need to modify the port in yaml.

6. Train:

python train.py

We provide Pix2pix, CycleGAN, RegGAN trained weights under the condition of Noise.0: https://drive.google.com/file/d/1xWXB9u6dQ9ZytmgQl_0ph4H_Ivtd41zJ/view?usp=sharing
