Since I'm learning frequency domain and I'm really curios about this topic, I'm trying to solve a problem (that I have already solved it using morphology [detecting lines by their thickness]) in frequency space (I know it's possible). here it is the picture:
I'm not sure but I think peaks on horizontal and vertical line are the noises (paper lines) and I've tried so many ways to remove them and none of them works. I'm not looking for a code and just wanna learn how it works and some tips to solve the problem. I really appreciate your kind contribution in advance.
Results after removing peaks:
Now I'm pretty sure I'm doing something wrong in detecting peaks (I've no idea what kind of peaks I'm looking for)
