HW#3: Frequency Domain ProcessingHW#3: Frequency Domain Processing

Obtain the 2D DFT of the following images: FigProb4.09(left).pgm image_hw3_2 Fig5.05(a).pgm

Apply the following filters to the above images: Gaussian low-pass filtering with D0=20

High-pass filtering using the above filter(Hhp=1-Hlp)

Verify the result of Prob.4.9 using your program (Use FigProb4.09(left).pgm).

Implement the periodic noise reduction filter as is described in Sect.5.4.1 (Use Fig5.05(a).pgm).
