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！
