Tensorflow implementation of ICLR 2019 paper Exemplar Guided Unsupervised Image-to-Image Translation with Semantic Consistency

• python 3.6.9
• tensorflow-gpu (1.14.0)
• numpy (1.14.0)
• Pillow (5.0.0)
• scikit-image (0.13.0)
• scipy (1.0.1)
• matplotlib (2.0.0)

• Pretrained models: MNIST, MNIST_multi, GTA<->BDD, CelebA, VGG19
• Training & Testing data in tf-record format: MNIST, MNIST_multi. GTA<->BDD, CelebA. Note: For the GTA<->BDD experiment, the data are prepared with RGB images of 512x1024 resolution, and segmentation labels of 8 categories. They are provided used for further research. In our paper, we use RGB images of 256x512 resolution without and segmentation labels.
• Segmentation model Refer to DeepLab-ResNet-TensorFlow

You can skip this data preparation procedure if directly using the tf-record data files.

1. cd datasets
2. ./run_convert_mnist.sh to download and convert mnist and mnist_multi to tf-record format.
3. ./run_convert_gta_bdd.sh to convert the images and segmentation to tf-record format. You need to download data from GTA5 website and BDD website. Note: this script will reuse gta data downloaded and processed in ./run_convert_gta_bdd.sh
4. ./run_convert_celeba.sh to convert the images to tf-record format. You can directly download the prepared data or download and process data from CelebA website .

1. Replace the links data, logs, weights with your own directories or links.
2. Download VGG19 into 'weights' directory.
3. Download the tf-record training data to the data_parent_dir (default ./data).
4. Modify the data_parent_dir, checkpoint_dir and comment/uncomment the target experiment in the run_train_feaMask.sh and run_train_EGSCIT.sh scripts.
5. Run run_train_feaMask.sh to pretrain the feature mask network. Then run run_train_EGSCIT.sh.

1. Replace the links data, logs, weights with your own directories or links.
2. (Optional) Download the pretrained models to the checkpoint_dir (default ./logs).
3. Download the tf-record testing data to the data_parent_dir (default ./data).
4. Modify the data_parent_dir, checkpoint_dir and comment/uncomment the target experiment in the run_test_EGSCIT.sh script.
5. run run_test_EGSCIT.sh.
