There is no difference between kernels with size 25 and size 21 because their boarder elements are almost zero. I have not compare yet. In my opinion, the results would...

Dataset and Degradation Model

I have not read this CVPR2021 paper yet since our work was also previously submitted to CVPR2021. Thanks for your hard work.
