Image noise filtering
image-processing
Solution
What about filtering in the Fourier domain? If the noise is periodic then with any luck your noise will appear as a pair of nice pointy features in Fourier space, where you can filter them with a couple of Gaussians then transform back to real space and your periodic noise should be gone.
Problem
I am looking for inputs on an image noise filter method. A 9-pixel median filter does not work very well with dense noise. Noise is periodic (periods of 50 lines) and additive. Thanks, Bi
