Low-pass and High-pass Filtering

  1. Compute the 2D Fast Fourier Transform.
  2. Shift the zero-frequency component to the center of the spectrum.
  3. Inverse of the Step 2: Shift the zero-frequency component back to original location.
  4. Inverse of Step 1: Compute the 2D inverse Fast Fourier Transform.
