Just wondering what image processing techniques can remove some artifacts of parallel-line like streaks, which are shown in the red box in the above picture.
I was thinking about removing it from Fourier domain operation(I expected to see a strong response other than DC some where in Fourier spectrum, but I could not see anything I expected.)
So I am wondering
- how to locate those artifacts in an image,
- and what image processing techniques can possibly get rid of them?
Any pointer is highly appreciated. Thank you.
