- Pre-Trained models

The pre-trained model for track-2 (i.e. scaling of x2) is shared with the repository while the pre-trained model for the track-1 (i.e. scaling of x4) can be downloaded from the link.

- Training the model

To train from scratch, you need to set root directory and dataset directory into options/train/train_vkgenPSNR.json file. Then run the following command to start the training.

python train.py -opt PATH-to-json_file

- Testng the model

To test your pre-trained model, you need to set root directory and dataset directory into options/test/test_VKGen.json file. Then run the following command to start the training.

python test.py -opt PATH-to-json_file

To get the SR images using self-assemble technique, you need to run the following line of code.

python self_assemble_test.py -opt PATH-to-json_file

- Requirement of packages

The list of packages required to run the code is given in chasnet.yml file.
