Get Started
Pretrained Models
Downloading the pretrained models from this link and put them under experiments/pretrained_models folder
.
Test
We provide quick test code with the pretrained model.
-
Modify the paths to dataset and pretrained model in the following yaml files for configuration.
./options/test/test_C2_matching.yml ./options/test/test_C2_matching_mse.yml
-
Run test code for models trained using GAN loss.
python mmsr/test.py -opt "options/test/test_C2_matching.yml"
Check out the results in
./results
. -
Run test code for models trained using only reconstruction loss.
python mmsr/test.py -opt "options/test/test_C2_matching_mse.yml"
Check out the results in in
./results
Train
All logging files in the training process, e.g., log message, checkpoints, and snapshots, will be saved to ./experiments
and ./tb_logger
directory.
-
Modify the paths to dataset in the following yaml files for configuration.
./options/train/stage1_teacher_contras_network.yml ./options/train/stage2_student_contras_network.yml ./options/train/stage3_restoration_gan.yml
-
Stage 1: Train teacher contrastive network.
python mmsr/train.py -opt "options/train/stage1_teacher_contras_network.yml"
-
Stage 2: Train student contrastive network.
# add the path to *pretrain_model_teacher* in the following yaml # the path to *pretrain_model_teacher* is the model obtained in stage1 ./options/train/stage2_student_contras_network.yml python mmsr/train.py -opt "options/train/stage2_student_contras_network.yml"
-
Stage 3: Train restoration network.
# add the path to *pretrain_model_feature_extractor* in the following yaml # the path to *pretrain_model_feature_extractor* is the model obtained in stage2 ./options/train/stage3_restoration_gan.yml python mmsr/train.py -opt "options/train/stage3_restoration_gan.yml" # if you wish to train the restoration network with only mse loss # prepare the dataset path and pretrained model path in the following yaml ./options/train/stage3_restoration_mse.yml python mmsr/train.py -opt "options/train/stage3_restoration_mse.yml"

Webly-Reference SR Dataset
Check out our Webly-Reference (WR-SR) SR Dataset through this link! We also provide the baseline results for a quick comparison in this link.
Webly-Reference SR dataset is a test dataset for evaluating Ref-SR methods. It has the following advantages:
- Collected in a more realistic way: Reference images are searched using Google Image.
- More diverse than previous datasets.
