• Download testing (Set5, Set14, BSD100, Urban100, Manga109) datasets, place them in datasets/.

• Run the following scripts.

  You can change the testing configuration in YML file, like 'test_DCT_light_x2.yml'.

  # DCT, reproduces results in Table 3 of the main paper
  python basicsr/test.py -opt options/Test/test_DCT_light_x2.yml
  python basicsr/test.py -opt options/Test/test_DCT_light_x3.yml
  python basicsr/test.py -opt options/Test/test_DCT_light_x4.yml

• The output is in results.
