grid-like artifacts

[Ying156209]

Hi,
Thanks for the brilliant work and open source code. I ran the code with my own dataset, and I find that artifacts occurred sometimes. I also ran your trained model on summer-winter dataset and found the grid-like artifact still. Is there any idea why this happened?

Hi,

Usually, the checkerboard artifacts will be mitigated after longer training. Or you could try to replace deconv operation by other operations like upsampling (as stated in https://distill.pub/2016/deconv-checkerboard/)
