Complete MATLAB program. Do not use built-in function.

The function emphasizes the high frequency components of an image in the frequency domain. You also need to complete to the Butterworth filter as a step of implementing the high frequency emphasis one. Different values of a and b will be applied to the filter.

Code in high_freq_emphasis.m

Function FEIm=high_freq_emphasis(Im, a, b)

%emphasis the high frequency components of the image in the frequency domain. You will use %the Butterworth filter in the high_freq_emphasis function, you need to build a butterworth filter %in ButterWorth.m.

% e.g.:

%H=ButterWorth([m,n], 0.2, 1);

%The size of ButterWorth filter equal to the size of input image,

%The cutoff frequency is 0.2

% the order is 1

FEIm=?

Code in ButterWorth.m.

Function f=ButterWorth(sze, cutoff, n)

f=
