Cannot reproduce the psnr value on Set14 #5

Closed gzhcv closed 2 years ago

gzhcv commented 2 years ago

Hi, i tested the psnr value on Set14 using the lut provided in this repo Model_S_x4_4bit_int8.npy, and get the value 26.41, which is different from paper that is 27.01. I used python package PIL to generate low resoultion image of Set14 (bicubic mode).

So i'm curious about why there is such a big difference.

Thanks for your sharing, hope for your reply

Hi, The PSNR value is from the LR images of Matlab bicubic downsampling, and PIL's method can be different.
