  1. HW#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). [Due: 11/14]
