DMIT

Pytorch implementation of our paper: "Multi-mapping Image-to-Image Translation via Learning Disentanglement".

Dependencies

you can install all the dependencies by

pip install -r requirements.txt

Getting Started

Datasets

• Download and unzip preprocessed datasets by

  • Season Transfer

     bash ./scripts/download_datasets.sh summer2winter_yosemite
    

  • Semantic Image Synthesis

     bash ./scripts/download_datasets.sh birds
    

• Or you can manually download them from CycleGAN and AttnGAN.

Training

• Season Transfer

   bash ./scripts/train_season_transfer.sh
  

• Semantic Image Synthesis

   bash ./scripts/train_semantic_image_synthesis.sh
  

• To view training results and loss plots, run python -m visdom.server and click the URL http://localhost:8097. More intermediate results can be found in environment exp_name.

Testing

• Run

   bash ./scripts/test_season_transfer.sh
   bash ./scripts/test_semantic_image_synthesis.sh
  

• The testing results will be saved in checkpoints/{exp_name}/results directory.

Pretrained Models

Pretrained models can be downloaded from Google Drive or Baidu Wangpan with code 59tm.

Custom Experiment

You can implement your Dataset and SubModel to start a new experiment.
