How to remove horizontal and vertical artefacts from image

51 views (last 30 days)
I have some images that where stiched together from multiple images and now after the calculations these stich lines which look like a grid remain as artefacts in the images.
I tried many ways to get rid of them but none worked realy well. I tried some gradient filtering replace edges detected by a soble filter with mean values, tried to cut of frequencies in a fft2, none worked satisfying. Combining the images (like substracting image 1300N from 2500N) doesnt work either, because in every image the stitch lines are at slightly different locations
Is there another idea how to approach? I attached the images and the data below.
Many thanks in advance.
Best regards
