Dataset and Pre-trained models

For super-resolution, we use DIV2K dataset to train and validate a model. You can download it here

After training, we evaluate trained models with benchmark datasets (Set14 - Zeyde et al. LNCS 2010, B100 - Martin et al. ICCV 2001, and Urban100 - Huang et al. CVPR 2015). You can download them here.

Unpack the downloaded tar files and change the args.dir_data in super-resolution/src/option.py to the directory where the DIV2K and benchmark datasets are located.

Since our method is applied to pre-trained models, you should download them through link, make a directory mkdir super-resolution/pretrained, and place the downloaded models in the directory.

Usage

Clone this repository.

git clone https://github.com/JungHunOh/SLS_CVPR2022.git
cd SLS_CVPR2022

cd super-resolution/src

For training,

bash ./scripts/train_sls_carnX4.sh $gpu $target_budget  # Training on DIV2K

For test,

bash ./scripts/test_sls_carnX4.sh $gpu $exp_name    # Test on Set14, B100, Urban100

To see the computational costs (w.r.t MACs and Num. Params.) of a trained model,

bash ./scripts/compute_costs.sh $gpu $model_dir
