[Paper link] | [ICCV version] | [Diffusers 🧨 implementation] | [HuggingFace 🤗 demo]

Updates

[Oct 13 2022] Code released. Section 4.3 of the earliest ArXiv version is open-sourced at Unified Generative Zoo.

[Nov 9 2022] CycleDiffusion is now available as a pipeline on HuggingFace 🤗 Diffusers 🧨. Please check the pipeline doc.

[Nov 10 2022] A demo built with HuggingFace 🤗 Spaces is available at Stable CycleDiffusion.

Overview

We think the randomness in diffusion models is like magic! Accumulated evidence has shown that fixing the "random seed" helps diffusion models generate images from two image distributions with minimal differences. Our paper is exactly about how to formalize this "random seed" and how to infer it from a given real image.

Our formalization and derivation are purely by definition, while we show that some amazing consequences follow! This repository contains code for CycleDiffusion, an embarrassingly simple method capable of

  1. Zero-shot image-to-image translation with text-to-image diffusion models such as Stable Diffusion.
  2. Traditional unpaired image-to-image translation with diffusion models trained on two related domains.

Check our results on zero-shot image-to-image translation below! We formulate the task input as a triplet $(\boldsymbol{x}, \boldsymbol{t}, \hat{\boldsymbol{t}})$:

  1. $\boldsymbol{x}$ is the source image, displayed with a purple margin.
  2. $\boldsymbol{t}$ is the source text, with text spans marked in purple.
  3. $\hat{\boldsymbol{t}}$ is the target text, with text spans abbreviated as $[\ldots]$ if overlapped with the source text.

We used Stable Diffusion in our experiments. Notably, all source images $\boldsymbol{x}$ are real images! Yes, you find that some of them are generated by DALL∙E 2, but these images can be seen as real for Stable Diffusion :)


Here are some comparisons with baselines.

Contents

Dependencies

  1. Create an environment by running
conda env create -f environment.yml
conda activate generative_prompt
pip install git+https://github.com/openai/CLIP.git
  1. Install torch and torchvision based on your CUDA version.
  2. Install taming-transformers by running
cd ../
git clone [email protected]:CompVis/taming-transformers.git
cd taming-transformers/
pip install -e .
cd ../
  1. Set up wandb for logging (registration is required). You should modify the setup_wandb function in main.py to accomodate your wandb credentials. You may want to run something like
wandb login

Evaluation data

  1. Most data for zero-shot image-to-image translation are already included in data/. Some images are from the AFHQ validation set, detailed below.
  2. Prepare the AFHQ validation set for unpaired image-to-image translation (also for some images used by zero-shot image-to-image translation) by running
git clone [email protected]:clovaai/stargan-v2.git
cd stargan-v2/
bash download.sh afhq-v2-dataset

Usage

Zero-shot image-to-image translation with text-to-image diffusion models

  1. Zero-shot image-to-image translation with Stable Diffusion v1-4. We divided the 128 test samples into 8 groups (16 samples in each group), so the averaged metrics are reported.

Customized use for zero-shot image-to-image translation

  1. Add your own image path and source-target text pairs at the end of this json file. You can add as many as you want.
  2. Suggested hyperparameter tuning in this config file
  • decoder_unconditional_guidance_scales: larger value means more weight on the target text
  • skip_steps: larger value means more similar to the original image
  • random seed: different random seed will generate different results
  1. Note that each combination of decoder_unconditional_guidance_scales $\times$ skip_steps will be enumerated, and the best one is returned.
  2. Run the following command to generate the image. Outputs will be saved in the output folder.
