How to eliminate periodic frequencies (line processing) from image and what parameters to use?

I am trying to figure out how to determine parameters to eliminate certain frequencies to remove the fence (see code attached). What should the amplitude threshold be? How do I know which rows/columns to set equal to 0? I tried playing around with some values but the adjusted image is mostly black and not filtering anything out.

Hi,

As I understand, you would like to perform fence removal from the image. My research and exploration have found that deep-learning techniques address this problem very well. I would refer you to go through the following IEEEAccess paper "IEEE Xplore Full-Text PDF:" for fence removal from an image

The paper's authors have released the MATLAB code and the dataset to train, validate and test the model. The link for the same is as follows:-

Hope this helps!
