-<!-- ## Notes of this project
-The code originates from our research project and the aim is to demonstrate the research idea, so we have not optimized it from a product perspective. And we will spend time to address some common issues, such as out of memory issue, limited resolution, but will not involve too much in engineering problems, such as speedup of the inference, fastapi deployment and so on. **We welcome volunteers to contribute to this project to make it more usable for practical application.** -->
-
-## :sparkles: News
-The framework now supports the restoration of high-resolution input.
-
-<img src='imgs/HR_result.png'>
-
-Training code is available and welcome to have a try and learn the training details. 
-
-You can now play with our [Colab](https://colab.research.google.com/drive/1NEm6AsybIiC5TwTU_4DqDkQO0nFRB-uA?usp=sharing) and try it on your photos. 
-
-## Requirement

-
-## :rocket: How to use?
-
-**Note**: GPU can be set 0 or 0,1,2 or 0,2; use -1 for CPU
-
-### 1) Full Pipeline
-
-You could easily restore the old photos with one simple command after installation and downloading the pretrained model.
-
-For images without scratches:
-
-```
-python run.py --input_folder [test_image_folder_path] \
-              --output_folder [output_path] \
-              --GPU 0
-```
-
-For scratched images:
-
-```
-python run.py --input_folder [test_image_folder_path] \
-              --output_folder [output_path] \
-              --GPU 0 \
-              --with_scratch
-```
-
-**For high-resolution images with scratches**:
-
-```
-python run.py --input_folder [test_image_folder_path] \
-              --output_folder [output_path] \
-              --GPU 0 \
-              --with_scratch \
-              --HR
-```
-
-Note: Please try to use the absolute path. The final results will be saved in `./output_path/final_output/`. You could also check the produced results of different steps in `output_path`.
-
-### 2) Scratch Detection
-
-Currently we don't plan to release the scratched old photos dataset with labels directly. If you want to get the paired data, you could use our pretrained model to test the collected images to obtain the labels.
-
-```
-cd Global/
-python detection.py --test_path [test_image_folder_path] \
-                    --output_dir [output_path] \
-                    --input_size [resize_256|full_size|scale_256]
-```
-

-
-### 3) Global Restoration
-
-A triplet domain translation network is proposed to solve both structured degradation and unstructured degradation of old photos.
-
-<p align="center">
-<img src='imgs/pipeline.PNG' width="50%" height="50%"/>
-</p>
-
-```
-cd Global/
-python test.py --Scratch_and_Quality_restore \
-               --test_input [test_image_folder_path] \
-               --test_mask [corresponding mask] \
-               --outputs_dir [output_path]
-
-python test.py --Quality_restore \
-               --test_input [test_image_folder_path] \
-               --outputs_dir [output_path]
-```
-

-
-
-### 4) Face Enhancement
-
-We use a progressive generator to refine the face regions of old photos. More details could be found in our journal submission and `./Face_Enhancement` folder.

-
-> *NOTE*: 
-> This repo is mainly for research purpose and we have not yet optimized the running performance. 
-> 
-> Since the model is pretrained with 256*256 images, the model may not work ideally for arbitrary resolution.
-
-### 5) GUI
-
-A user-friendly GUI which takes input of image by user and shows result in respective window.
-
-#### How it works:
-
-1. Run GUI.py file.
-2. Click browse and select your image from test_images/old_w_scratch folder to remove scratches.
-3. Click Modify Photo button.
-4. Wait for a while and see results on GUI window.
-5. Exit window by clicking Exit Window and get your result image in output folder.

-## How to train?
-
-### 1) Create Training File
-
-Put the folders of VOC dataset, collected old photos (e.g., Real_L_old and Real_RGB_old) into one shared folder. Then
-```
-cd Global/data/
-python Create_Bigfile.py
-```
-Note: Remember to modify the code based on your own environment.
-
-### 2) Train the VAEs of domain A and domain B respectively
-
-```
-cd ..
-python train_domain_A.py --use_v2_degradation --continue_train --training_dataset domain_A --name domainA_SR_old_photos --label_nc 0 --loadSize 256 --fineSize 256 --dataroot [your_data_folder] --no_instance --resize_or_crop crop_only --batchSize 100 --no_html --gpu_ids 0,1,2,3 --self_gen --nThreads 4 --n_downsample_global 3 --k_size 4 --use_v2 --mc 64 --start_r 1 --kl 1 --no_cgan --outputs_dir [your_output_folder] --checkpoints_dir [your_ckpt_folder]
-
-python train_domain_B.py --continue_train --training_dataset domain_B --name domainB_old_photos --label_nc 0 --loadSize 256 --fineSize 256 --dataroot [your_data_folder]  --no_instance --resize_or_crop crop_only --batchSize 120 --no_html --gpu_ids 0,1,2,3 --self_gen --nThreads 4 --n_downsample_global 3 --k_size 4 --use_v2 --mc 64 --start_r 1 --kl 1 --no_cgan --outputs_dir [your_output_folder]  --checkpoints_dir [your_ckpt_folder]
-```
-Note: For the --name option, please ensure your experiment name contains "domainA" or "domainB", which will be used to select different dataset.
-
-### 3) Train the mapping network between domains
-
-Train the mapping without scratches:
-```
-python train_mapping.py --use_v2_degradation --training_dataset mapping --use_vae_which_epoch 200 --continue_train --name mapping_quality --label_nc 0 --loadSize 256 --fineSize 256 --dataroot [your_data_folder] --no_instance --resize_or_crop crop_only --batchSize 80 --no_html --gpu_ids 0,1,2,3 --nThreads 8 --load_pretrainA [ckpt_of_domainA_SR_old_photos] --load_pretrainB [ckpt_of_domainB_old_photos] --l2_feat 60 --n_downsample_global 3 --mc 64 --k_size 4 --start_r 1 --mapping_n_block 6 --map_mc 512 --use_l1_feat --niter 150 --niter_decay 100 --outputs_dir [your_output_folder] --checkpoints_dir [your_ckpt_folder]
-```
-
-
-Traing the mapping with scraches:
-```
-python train_mapping.py --no_TTUR --NL_res --random_hole --use_SN --correlation_renormalize --training_dataset mapping --NL_use_mask --NL_fusion_method combine --non_local Setting_42 --use_v2_degradation --use_vae_which_epoch 200 --continue_train --name mapping_scratch --label_nc 0 --loadSize 256 --fineSize 256 --dataroot [your_data_folder] --no_instance --resize_or_crop crop_only --batchSize 36 --no_html --gpu_ids 0,1,2,3 --nThreads 8 --load_pretrainA [ckpt_of_domainA_SR_old_photos] --load_pretrainB [ckpt_of_domainB_old_photos] --l2_feat 60 --n_downsample_global 3 --mc 64 --k_size 4 --start_r 1 --mapping_n_block 6 --map_mc 512 --use_l1_feat --niter 150 --niter_decay 100 --outputs_dir [your_output_folder] --checkpoints_dir [your_ckpt_folder] --irregular_mask [absolute_path_of_mask_file]
-```
-
