Hello authors, I think SRGAN is somewhat in line with my research, and I would like to modify the functionality of SRGAN so that it can generate larger-scale images instead of increasing resolution.For example, a 2m2m rock image is generated based on a 2cm2cm rock training dataset.What code should I modify to meet my needs? Thank you
