vs hires.fix ?

[lxy2017]

Very nice work, I have some questions, the paper focuses on solving the problem of object duplication in generating high resolution images, although it is possible to generate a higher resolution, the clarity of the image does not seem to be solved, this should still need to be solved by training high resolution images? Also what are the advantages of this approach over the hires fix used in web ui? Thank you for your answer.
