News

(2024-9-4) PASD-SDXL are now publicly available. Please have a try via python3 test_pasd_sdxl.py!

(2024-8-15) PASD-SDXL will be released soon. It surpasses the PASD-SD1.5 a lot. Stay tuned!

(2024-7-1) Accepted by ECCV2024. A new version of our paper will be updated soon.

(2024-3-18) Please have a try on our colorization model via python test_pasd.y --pasd_model_path runs/pasd_color/checkpoint-180000 --control_type grayscale --high_level_info caption --use_pasd_light. You should use the noise scheduler provided in runs/pasd_color/scheduler which has been updated to ensure zero-terminal SNR in order to avoid the leaking residual signal from RGB image during training. Please read the updated paper for more details.

(2024-3-18) We have updated the paper. The weights and datasets are now available on Huggingface.

(2024-1-16) You may also want to check our new updates SeeSR and Phantom.

(2023-10-20) Add additional noise level via --added_noise_level and the SR result achieves a great balance between "extremely-detailed" and "over-smoothed". Very interesting!. You can control the SR's detail level freely.

(2023-10-18) Completely solved the issues by initializing latents with input LR images. Interestingly, the SR results also become much more stable.

(2023-10-11) Colab demo is now available. Credits to Masahide Okada.

(2023-10-09) Add training dataset.

(2023-09-28) Add tiled latent to allow upscaling ultra high-resolution images. Please carefully set latent_tiled_size as well as --decoder_tiled_size when upscaling large images.

(2023-09-12) Add Gradio demo.

(2023-09-11) Upload pre-trained models.

(2023-09-07) Upload source codes.

Our model can do various tasks. Hope you can enjoy it.

Realistic Image SR

Old photo restoration

Personalized Stylization

Colorization

Installation

Installation using pip

The package is not yet hosted in PyPI, so please install from github:

#pip install torch  # required by xformers, which is unavailable on Mac

pip install git+https://github.com/yangxy/PASD.git
#or: pip install git+ssh://git@github.com/yangxy/PASD.git

Download checkpoint config files from main branch to local directory ./checkpoints:

wget -O - https://github.com/yangxy/PASD/archive/main.tar.gz | tar xz --strip=1 "PASD-main/checkpoints"

After this, download model pickle files to the ./checkpoints and you'll be able to create models via from_pretrained().

Development

  • Clone this repository:
git clone https://github.com/yangxy/PASD.git
cd PASD
pip install -e .
bash ./train_pasd.sh

if you want to train pasd_light, use --use_pasd_light.

  • Test PASD.

Download our pre-trained models pasd | pasd_rrdb | pasd_light | pasd_light_rrdb, and put them into runs/.

pip install -r requirements-test.txt  # install additional dependencies
python test_pasd.py # --use_pasd_light --use_personalized_model

Please read the arguments in test_pasd.py carefully. We adopt the tiled vae method proposed by multidiffusion-upscaler-for-automatic1111 to save GPU memory.

Please try --use_personalized_model for personalized stylizetion, old photo restoration and real-world SR. Set --conditioning_scale for different stylized strength.

We use personalized models including majicMIX realistic(for SR and restoration), ToonYou(for stylization) and modern disney style(unet only, for stylization). You can download more from communities and put them into checkpoints/personalized_models.

If the default setting does not yield good results, try different --pasd_model_path, --seed, --prompt, --upscale, or --high_level_info to get better performance.

  • Gradio Demo
python gradio_pasd.py
