Results of released test code

[NasrinR791]

Hi dear @tT0NG ,
Thank you for your great work and for sharing the model. I tried your released test code ( MAINTHREAD_test.py) on the validation set of NTIRE2019 ( images 46,...,50), however, the PSNR and SSIM results are not the same with the paper.
Did you do special preprocessing or post processing? If you did crop or resize the input images, could you please share the details?
