I am trying to binarize the CT images if the samples. Some of the images have ring artifacts and I want to remove them. I found in the website of xlib and the paper _Stripe and ring artifact removal with combined wavelet — Fourier filtering_that I can use the plugin Stripes Filter to do this. However, it seems that the Stripes Filter can only remove vertical and horizontal stripes. I wonder if there is a way to set the parameters to let it remove ring artifacts. An example of ring artifacts is shown below.
Thank you very much!
