Intra-Source Style Augmentation for Improved Domain Generalization (ISSA)

Official PyTorch implementation of the WACV 2023 paper "Intra-Source Style Augmentation for Improved Domain Generalization". This repository provides the minimal code snippets of the masked noise encoder for GAN inversion.

🔥 Updates: "Intra- & Extra-Source Exemplar-Based Style Synthesis for Improved Domain Generalization" has been accepted at International Journal of Computer Vision (IJCV)! We extended our WACV paper and add more applications, e.g., utilzing stylized data for assessing domain generalization performance. Please check it out and reach out in case of any questions!

Getting Started

The code is tested for Python 3.9. ISSA conda environment can be created via

conda env create --file environment.yml
source activate issa

Training

Note: please read how-to.pdf for more detailed instruction. After proper path configuration in configs/mne_training.yml, run the command below for training the encoder

python train_encoder.py

Some important paths need to be adjusted in the configuration file:

• data: path to the real data
• data_fake: path to the GAN generated data, where the corresponding w latents are stored in the same path
• pkl_dir: path to the pretrained GAN model

Inference

For inference, please refer to the code snippets here, which shows how the Encoder & Generator are used for image generation.
