JPEG quality range in CIR dataset

Dear @renyulin-f,

Thank you for interest research!

I downloaded the CIR dataset and noticed that the distortion levels of JPEG differ between the training and some test sets:

  • Training set: Q=10, 15, 20
  • Test set (BSDS, Classic5, and ICB): Q=10, 15, 20
  • Test set (DIV2K_test and LIVE1): Q=5, 10, 15

In Appendix B, Table 5 reports results for JPEG Q=10, 15, 20, and the unseen task dataset, particularly Cross Degree JPEG, includes Q=5.

Could you check the codec file in CIR_dataset/Test_Compressed_Dataset/DIV2K_test and LIVE1?
