About visualization

[iceCream-sh]

Thank you very much for your work, but when I realized the visualization of the frequency domain filter, the image is different from the one you provided. And I would like to ask how to realize the visualization of the spatial domain

Hi, thanks for your interest in our work. We provide the ipynb file to visualize the filter. I just rerun the code and it seems the output is the same as the given image in our environment (PyTorch 1.8.1).
