I am working on Electron Microscopy (EM) images. There are some lattice pattern inside images that I want to remove. I am using following approach:
Perform Fourier Transform (FFT)
Remove certain frequencies
Perform Inverse Fourier Transform (IFT)
I know about FT and IFFT, but don’t know how can I remove / lower the certain frequencies so that I can remove the lattice pattern when I perform IFT on a fourier transformed image.
Is there any approach in imageJ for removing the lattice pattern from image? or can anybody guide in this regard please?
