Step 2: Saving the size of the input image in pixels. Step 3: Get the Fourier Transform of the input_image. Step 4: Assign the order and cut-off frequency. Step 5: Designing filter: Butterworth Low Pass Filter. Step 6: Convolution between the Fourier Transformed input image and the filtering mask. WebButterworth filters are characterized by a magnitude response that is maximally flat in the passband and monotonic overall. Butterworth filters sacrifice rolloff steepness for monotonicity in the pass- and stopbands. Unless the smoothness of the Butterworth filter is needed, an elliptic or Chebyshev filter can generally provide steeper rolloff ... plastic dining chair set
