It seems SwinIR doesn't use patch merging.

Excellent work!
It seems that there is not patch merging.So it means different windows can't exchange information.I understand you don't want to downsample,but maybe the windows should connect with each other.

The windows can exchange information because the swin transformer blocks used are alternating between not shifted/shifted. When the shifted version is used (odd indexes) neighboring windows will be able to exchange information.

I have the same confusion. How do you understand this question finally .
