I want to make an anti-aliasing 2D lowpass diamond filter of like 15×15, I know we need to have a lowpass filter and a highpass filter to do that, but how do I know the pass band and stop band of a certain image with dimensions m*n

may be use fft2 to make image to frequency domain， and use Butterworth band-stop filter to filter it
