Description:
Image Processing: Frequency Domain Enhancement
Generate noisy versions of the cameraman image by adding noise with the following characteristics:
Uniform with mean 40 and standard deviation 20
Gaussian of mean 40 and standard deviation 20
Salt and pepper noise density of 10 percent
Filter the resulting noisy images using:
1. Ideal low pass
with the following values of ro: 50, 30, and 20
2. Butterworth filters
with the following values of ro: 50, 30, and 20
3. Gaussian filters
with the following values of sigma: 30, 20, and 10
Show and label the magnitude spectra of your filters for all the above cases
Show noisy and filtered images for all the above cases
