only PSNR and SSIM

[zzctmd]

HI! thanks for the great job!
When I use different calculation metrics in pyiqa to evaluate the results,there is a performance gap between the PSNR and SSIM results and the results reported in paper. The results of other metrics are nearly identical to the results reported in paper .
I use center crop on RealSR image to get a 128×128 patch and calculate on the Y channel in YCbCrspace.
our results : PSNR :24.63 SSIM :0.7195
results on the paper : PSNR :25.15 SSIM:0.7341
May I ask what's wrong with my approach? Others,could you provide the code for the metric testing. Thanks！

Hello, we directly used the test set from the StableSR release for testing. We have also uploaded the script for testing IQA and our results.
