Image filtering using built in function FFT2 and IFT2. Bonus Problem

Bonus Problem (100 point): Image Processing Problem Suppose that we use the LTI filter to process the input image of 'Lenna_NEW.png' as shown in the figure given below. The filter coefficients (in the frequency domain) are all 3. Obtain the output image of the filter.
