Updates

[2023.10.25] Added dataset links for training and testing.
[2023.10.13] Added the Replicate demo and api🔥. Thanks to @chenxwh!!! We updated the Hugging Face demo🔥 and online Colab demo🔥. Thanks to @fffiloni and @camenduru !!! We also made a Model Card in Hugging Face 🤗 and provided more examples for testing.
[2023.10.09] The pretrained weights of DA-CLIP and the Universal IR model are released in link1 and link2, respectively. In addition, we also provide a Gradio app file for the case that you want to test your own images.

Notice!!

🙁 In testing we found that the current pretrained model is still difficult to process some real-world images which might have distribution shifts with our training dataset (captured from different devices or with different resolutions or degradations). We regard it as a future work and will try to make our model more practical! We also encourage users who are interested in our work to train their own models with larger dataset and more degradation types.

🙁 BTW, we also found that directly resizing input images will lead a poor performance for most tasks. We could try to add the resize step into the training but it always destroys the image quality due to interpolation.

🙁 For the inpainting task our current model only supports face inpainting due to the dataset limitation. We provide our mask examples and you can use the generate_masked_face script to generate uncompleted faces.

How to Run the Code?

Dependencies

• OS: Ubuntu 20.04
• nvidia:
  • cuda: 11.4
• python 3.8

Install

We advise you first create a virtual environment with:

python3 -m venv .env
source .env/bin/activate
pip install -U pip
pip install -r requirements.txt

DA-CLIP Usage

Get into the universal-image-restoration directory and run:

import torch
from PIL import Image
import open_clip

checkpoint = 'pretrained/daclip_ViT-B-32.pt'
model, preprocess = open_clip.create_model_from_pretrained('daclip_ViT-B-32', pretrained=checkpoint)
tokenizer = open_clip.get_tokenizer('ViT-B-32')

image = preprocess(Image.open("haze_01.png")).unsqueeze(0)
degradations = ['motion-blurry','hazy','jpeg-compressed','low-light','noisy','raindrop','rainy','shadowed','snowy','uncompleted']
text = tokenizer(degradations)

with torch.no_grad(), torch.cuda.amp.autocast():
    text_features = model.encode_text(text)
    image_features, degra_features = model.encode_image(image, control=True)
    degra_features /= degra_features.norm(dim=-1, keepdim=True)
    text_features /= text_features.norm(dim=-1, keepdim=True)

    text_probs = (100.0 * degra_features @ text_features.T).softmax(dim=-1)
    index = torch.argmax(text_probs[0])

print(f"Task: {task_name}: {degradations[index]} - {text_probs[0][index]}")

Dataset Preparation

Preparing the train and test datasets following our paper Dataset Construction section as:

#### for training dataset ####
#### (uncompleted means inpainting) ####
datasets/universal/train
|--motion-blurry
|  |--LQ/*.png
|  |--GT/*.png
|--hazy
|--jpeg-compressed
|--low-light
|--noisy
|--raindrop
|--rainy
|--shadowed
|--snowy
|--uncompleted

#### for testing dataset ####
#### (the same structure as train) ####
datasets/universal/val
...

#### for clean captions ####
datasets/universal/daclip_train.csv
datasets/universal/daclip_val.csv

Then get into the universal-image-restoration/config/daclip-sde directory and modify the dataset paths in option files in options/train.yml and options/tes.yml.

You can add more tasks or datasets to both train and val directories and add the degradation word to distortion.

Dataset Links

Degradation	motion-blurry	hazy	jpeg-compressed*	low-light	noisy* (same to jpeg)
Datasets	Gopro	RESIDE-6k	DIV2K+Flickr2K	LOL	DIV2K+Flickr2K

Degradation	raindrop	rainy	shadowed	snowy	uncompleted
Datasets	RainDrop	Rain100H	SRD	Snow100K	CelebaHQ-256

You should only extract the train datasets for training, and all validation datasets can be downloaded in the Google drive. For jpeg and noisy datasets, you can generate LQ images using this script.

Training

DA-CLIP

See DA-CLIP.md for details.

Universal Image Restoration

The main code for training is in universal-image-restoration/config/daclip-sde and the core network for DA-CLIP is in universal-image-restoration/open_clip/daclip_model.py.

• Put the pretrained DA-CLIP weights to pretrained directory and check the daclip path.

• You can then train the model following below bash scripts:

cd universal-image-restoration/config/daclip-sde

# For single GPU:
python3 train.py -opt=options/train.yml

# For distributed training, need to change the gpu_ids in option file
python3 -m torch.distributed.launch --nproc_per_node=2 --master_poer=4321 train.py -opt=options/train.yml --launcher pytorch

The models and training logs will save in log/universal-ir. You can print your log at time by running tail -f log/universal-ir/train_universal-ir_***.log -n 100.

Evaluation

To evalute our method on image restoration, please modify the benchmark path and model path and run

cd universal-image-restoration/config/universal-ir
python test.py -opt=options/test.yml

Gradio

Here we provide an app.py file for testing your own images. Before that, you need to download the pretrained weights (DA-CLIP and UIR) and modify the model path in options/test.yml. Then by simply running python app.py, you can open http://localhost:7860 to test the model. (We also provide several images with different degradations in the images dir). We also provide more examples from our test dataset in the google drive.
