chmod a+x install_env.sh && ./install_env.sh| Model Name | Description |
|---|---|
| general_swinir_v1.ckpt | Stage1 model (SwinIR) for general image restoration. |
| general_full_v1.ckpt | Full model for general image restoration. "Full" means it contains both the stage1 and stage2 model. |
| face_swinir_v1.ckpt | Stage1 model (SwinIR) for face restoration. |
| face_full_v1.ckpt | Full model for face restoration. |
Download general_full_v1.ckpt and general_swinir_v1.ckpt, then run the following command to interact with the gradio website.
python gradio_diffbir.py --ckpt [full_ckpt_path] --config configs/model/cldm.yaml --reload_swinir --swinir_ckpt [swinir_ckpt_path]
Download general_full_v1.ckpt and general_swinir_v1.ckpt, then put your low-quality (lq) images in lq_dir. If you are confused about where the reload_swinir option came from, please refer to the degradation details.
python inference.py --config configs/model/cldm.yaml --ckpt [full_ckpt_path] --reload_swinir --swinir_ckpt [swinir_ckpt_path] --steps 50 --input [lq_dir] --sr_scale 1 --image_size 512 --color_fix_type wavelet --resize_back --output [output_dir_path]Download face_full_v1.ckpt and put your low-quality (lq) images in lq_dir.
python inference.py --config configs/model/cldm.yaml --ckpt [full_ckpt_path] --steps 50 --input [lq_dir] --sr_scale 1 --image_size 512 --color_fix_type wavelet --resize_back --output [output_dir_path]Download general_swinir_v1.ckpt, face_swinir_v1.ckpt for general, face image respectively, and put your low-quality (lq) images in lq_dir:
python scripts/inference_stage1.py --config configs/model/swinir.yaml --ckpt [swinir_ckpt_path] --input [lq_dir] --sr_scale 1 --image_size 512 --output [output_dir_path]Since the proposed two-stage pipeline is very flexible, you can utilize other awesome models to remove degradations instead of SwinIR and then leverage the Stable Diffusion to refine details.
# step1: Use other models to remove degradations and save results in [img_dir_path].
# step2: Refine details of step1 outputs.
python inference.py --config configs/model/cldm.yaml --ckpt [full_ckpt_path] --steps 50 --input [img_dir_path] --sr_scale 1 --image_size 512 --color_fix_type wavelet --resize_back --output [output_dir_path] --disable_preprocess_modelFor general image restoration, we first train both the stage1 and stage2 model under codeformer degradation to enhance the generative capacity of the stage2 model. In order to improve the ability for degradation removal, we train another stage1 model under Real-ESRGAN degradation and utilize it during inference.
For face image restoration, we adopt the degradation model used in DifFace for training and directly utilize the SwinIR model released by them as our stage1 model.

Generate file list of training set and validation set.
python scripts/make_file_list.py --img_folder [hq_dir_path] --val_size [validation_set_size] --save_folder [save_dir_path] --follow_links
This script will collect all image files in
img_folderand split them into training set and validation set automatically. You will get two file lists insave_folder, each line in a file list contains an absolute path of an image file:save_folder ├── train.list # training file list └── val.list # validation file list -
Configure training set and validation set.
For general image restoration, fill in the following configuration files with appropriate values.
- training set and validation set for CodeFormer degradation.
- training set and validation set for Real-ESRGAN degradation.
For face image restoration, fill in the face training set and validation set configuration files with appropriate values.
-
Configure training-related information.
Fill in the configuration file of training with appropriate values.
-
Start training.
python train.py --config [training_config_path]
💡:Checkpoints of SwinIR will be used in training stage2 model.
-
Download pretrained Stable Diffusion v2.1 to provide generative capabilities.
wget https://huggingface.co/stabilityai/stable-diffusion-2-1-base/resolve/main/v2-1_512-ema-pruned.ckpt --no-check-certificate
-
Create the initial model weights.
python scripts/make_stage2_init_weight.py --cldm_config configs/model/cldm.yaml --sd_weight [sd_v2.1_ckpt_path] --swinir_weight [swinir_ckpt_path] --output [init_weight_output_path]
You will see some outputs which show the weight initialization.
