Training & Evaluation

• Download the EPFL, HCInew, HCIold, INRIA and STFgantry datasets via Baidu Drive (key:7nzy) or OneDrive, and place the 5 datasets to the folder ./datasets/.
• Run Generate_Data_for_SSR_Training.py to generate training data, and begin to train the EPIT (on 5x5 by default) for 2x/4x SR:

  $ python train.py --scale_factor $2/4$

• Run Generate_Data_for_SSR_Test.py to generate evaluation data, and you can quick run test.py to perform network inference by using our released models.

  python test.py
