Consider the centered DFT for Bird 2.tif, re-synthesize the images using the DFT coefficients (1) inside (r < 30), and (2) outside (r 30) the circular region with radius=30 pixels (based on the original image size), plot the resulted images. Your report (Word or pdf format) should contain:
• Source codes (30%)
• Plot of DFT magnitude in Log scale (20%)
• Image constructed by DFT coefficients inside the circular region with radius = 30 pixels (15%)
• Image constructed by DFT coefficients outside the circular region with radius = 30 pixels (15%)
• Table of top 25 DFT frequencies (u,v) in the left half frequency region (0uM1, 0vN/21) (20%)
