QUESTION
(a) Describe the following Mean Filters used as Noise Reduction filters:
1. Arithmetic Mean Filter.
2. Geometric Mean Filer.
3. Harmonic Mean Filter.
You are also required to indicate which type of noise they are best adapted for.
(b) Differentiate between the Ideal Low Pass and Ideal High Pass filters in the Frequency domain using the Fourier Transform.
(c) Briefly give the steps of how you would perform filtering in the Frequency Domain.
