How to increase the resolution from 128*128 to 256*256？

[xiaobanni]

Thanks for this project.

In the original paper, it was mentioned that 'scaling all training images to a resolution of 128*128 pixels'. But the current website can produce 256*256 pictures.

How did you achieve this improvement? Better data set, image super-resolution or other methods?

Looking forward to your answers. Thanks in advance.
