Just a thought, but you can attempt to model the noise with something like MedianFilter[i, {0, 50}], (across 0 vertical, 50 horizontal pixels) which you could then try to subtract from the image.

Probably overthinking it, but you could transfer learn this U-Net on your working data to segment the image. But more than likely you can just solve this using some smart filtering (have a look at ImagePyramid)

| Jun 7, 2019 at 11:03 | comment | added | Letshin | Nope, sadly. I took a few images during that run. The last image I've attached in the question is an example of this - and there were no artefacts there. There must have been some fluctuations during the scanning process, maybe because the sample was (somewhat) magnetic. | |
