AttentionGAN-v2 for Unpaired Image-to-Image Translation

AttentionGAN-v2 Framework

The proposed generator learns both foreground and background attentions. It uses the foreground attention to select from the generated output for the foreground regions, while uses the background attention to maintain the background information from the input image. For refer to our papers for more details.

Installation

Clone this repo.

git clone https://github.com/Ha0Tang/AttentionGAN
cd AttentionGAN/

This code requires PyTorch 0.4.1+ and python 3.6.9+. Please install dependencies by

pip install -r requirements.txt (for pip users)

or

./scripts/conda_deps.sh (for Conda users)

To reproduce the results reported in the paper, you would need an NVIDIA TITAN Xp GPUs.

Dataset Preparation

Download the datasets using the following script. Please cite their paper if you use the data.

bash ./datasets/download_cyclegan_dataset.sh dataset_name

AttentionGAN Training/Testing

  • Download a dataset using the previous script (e.g., horse2zebra).
  • To view training results and loss plots, run python -m visdom.server and click the URL http://localhost:8097.
  • Train a model:
bash ./scripts/train_attentiongan.sh
  • To see more intermediate results, check out ./checkpoints/horse2zebra_attentiongan/web/index.html.
  • How to continue train? Append --continue_train --epoch_count xxx on the command line.
  • Test the model:
bash ./scripts/test_attentiongan.sh
  • The test results will be saved to a html file here: ./results/horse2zebra_attentiongan/latest_test/index.html.

Generating Images Using Pretrained Model

  • You need download a pretrained model (e.g., horse2zebra) with the following script:
bash ./scripts/download_attentiongan_model.sh horse2zebra
  • The pretrained model is saved at ./checkpoints/{name}_pretrained/latest_net_G.pth.
  • Then generate the result using
python test.py --dataroot ./datasets/horse2zebra --name horse2zebra_pretrained --model attention_gan --dataset_mode unaligned --norm instance --phase test --no_dropout --load_size 256 --crop_size 256 --batch_size 1 --gpu_ids 0 --num_test 5000 --epoch latest --saveDisk

The results will be saved at ./results/. Use --results_dir {directory_path_to_save_result} to specify the results directory. Note that if you want to save the intermediate results and have enough disk space, remove --saveDisk on the command line.

  • For your own experiments, you might want to specify --netG, --norm, --no_dropout to match the generator architecture of the trained model.

Evaluation Code

  • FID: Official Implementation
  • KID or Here: Suggested by UGATIT. Install Steps: conda create -n python36 pyhton=3.6 anaconda and pip install --ignore-installed --upgrade tensorflow==1.13.1
