Semantic Image Synthesis with DAGAN

Dual Attention GANs for Semantic Image Synthesis
Hao Tang¹, Song Bai², Nicu Sebe¹³.
¹University of Trento, Italy, ²University of Oxford, UK, ³Huawei Research Ireland, Ireland.
In ACM MM 2020.
The repository offers the official implementation of our paper in PyTorch.

In the meantime, check out our related CVPR 2020 paper Local Class-Specific and Global Image-Level Generative Adversarial Networks for Semantic-Guided Scene Generation and Arxiv paper Edge Guided GANs with Semantic Preserving for Semantic Image Synthesis.

Installation

Clone this repo.

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

This code requires PyTorch 1.0 and python 3+. Please install dependencies by

pip install -r requirements.txt

This code also requires the Synchronized-BatchNorm-PyTorch rep.

cd DAGAN_v1/
cd models/networks/
git clone https://github.com/vacancy/Synchronized-BatchNorm-PyTorch
cp -rf Synchronized-BatchNorm-PyTorch/sync_batchnorm .
cd ../../

To reproduce the results reported in the paper, you would need an NVIDIA DGX1 machine with 8 V100 GPUs.

Dataset Preparation

Please download the datasets on the respective webpages.

• Facades: 55.8M, here.
• DeepFashion: 592.3M, here.
• CelebAMask-HQ: 2.7G, here.
• Cityscapes: 8.4G, here.
• ADE20K: 953.7M, here.
• COCO-Stuff: 21.5G, here.

We also provide the prepared datasets for your convience.

sh datasets/download_dagan_dataset.sh [dataset]

where [dataset] can be one of facades, deepfashion, celeba, cityscapes, ade20k, or coco_stuff.

Generating Images Using Pretrained Model

1. Download the pretrained models using the following script,

sh scripts/download_dagan_model.sh GauGAN_DAGAN_[dataset]

where [dataset] can be one of cityscapes, ade, facades, or celeba.

2. Change several parameter and then generate images using test_[dataset].sh. If you are running on CPU mode, append --gpu_ids -1.
3. The outputs images are stored at ./results/[type]_pretrained/ by default. You can view them using the autogenerated HTML file in the directory.

Train and Test New Models

1. Prepare dataset.
2. Change several parameters and then run train_[dataset].sh for training. There are many options you can specify. To specify the number of GPUs to utilize, use --gpu_ids. If you want to use the second and third GPUs for example, use --gpu_ids 1,2.
3. Testing is similar to testing pretrained models. Use --results_dir to specify the output directory. --how_many will specify the maximum number of images to generate. By default, it loads the latest checkpoint. It can be changed using --which_epoch.
