I am trying to remove some ring artifacts from microtomography images (See the sample image in this post) that were captured in a synchrotron facility. There are multiple image stacks and the artifact happens randomly in some of the reconstructed images in every stack.
The artifact is not the ordinary ring artifact that is usually uniform and can be corrected during reconstruction of the raw tomography files into images. I have gone too far in the image processing and now want to segment and binerize the images but this artifact makes it less precise. The example you see is a sample of filtered images (anisotrpic filtering). Please advise!
If there is no way of correcting the images and I may have to do the reconstruction from raw radiographs, I would appreciate any comment on that. Have never done reconstruction in ImageJ. After reconstruction I will have to register different stacks to each other due to some drift during the experiment. Have not done this one with ImageJ either. Any comments on these are appreciated.
