We have presented the code for three types of highpass filtering in the frequency domain;
1. Ideal highpass filter (IHPF) (Problem?)
2. Butterworth highpass filter (BHPF)
3. Gaussian highpass filter (GHPF)
You can clearly observe the problem of the ringing effect in the output of the high pass filter.
Reason for ringing effect;
Convolution of any image (consisting of groups of impulses of
different strengths) with the ripple shaped function results in the
ringing phenomenon.
