JoJoGAN: One Shot Face Stylization

This is the PyTorch implementation of JoJoGAN: One Shot Face Stylization.

Abstract:<br> While there have been recent advances in few-shot image stylization, these methods fail to capture stylistic details that are obvious to humans. Details such as the shape of the eyes, the boldness of the lines, are especially difficult for a model to learn, especially so under a limited data setting. In this work, we aim to perform one-shot image stylization that gets the details right. Given a reference style image, we approximate paired real data using GAN inversion and finetune a pretrained StyleGAN using that approximate paired data. We then encourage the StyleGAN to generalize so that the learned style can be applied to all other images.

Updates

• 2021-12-22 Integrated into Replicate using cog. Try it out

• 2022-02-03 Updated the paper. Improved stylization quality using discriminator perceptual loss. Added sketch model <br><img src="teasers/sketch.gif" width="50%" height="50%"/>

• 2021-12-26 Added wandb logging. Fixed finetuning bug which begins finetuning from previously loaded checkpoint instead of the base face model. Added art model <details><br><img src="teasers/art.gif" width="50%" height="50%"/></details>

• 2021-12-25 Added arcane_multi model which is trained on 4 arcane faces instead of 1 (if anyone has more clean data, let me know!). Better preserves features <details><img src="teasers/arcane.gif" width="50%" height="50%"/></details>

• 2021-12-23 Paper is uploaded to arxiv.

• 2021-12-22 Integrated into Huggingface Spaces 🤗 using Gradio. Try it out

• 2021-12-22 Added pydrive authentication to avoid download limits from gdrive! Fixed running on cpu on colab.
