Fail to replicate PSNR of CUFED on paper

[wdmwhh]

Hello, thanks for sharing your great work.
I try to replicate PSNR (27.09) in Table 1 of the paper. As shown in Table 4, PSNR in L1 of CUFED5 (_1.png) is 26.99. I think that 27.09 is using multiple references (_1.png, *_2.png, *_3.png, *_4.png, *_5.png) without a second thought. Thus, I pad all the refs to size [500, 500] and vertically concat to be one big ref [2500, 500].
However, no matter which padding type is used, the PSNR is around 26.4, not to reach 27.09. Could you tell me some details to help?

What about your performance using only L1 ref?

What about your performance using only L1 ref?

26.991 (consistent with the paper)

Did you use resize to process different Refs? Resize will damage the performance.

Just pad each Ref to the left-top corner in each 500x500 zero image. Then concate them to 2500x500 image. There are no other tricks.

I didn't use resize. This is my code for TestSet_multi https://pastebin.com/n1DfaffB.

In addition, I have tried all borderTypes -- cv2.BORDER_CONSTANT, cv2.BORDER_REFLECT, cv2.BORDER_REFLECT_101, cv2.BORDER_REPLICATE,
cv2.BORDER_WRAP.
