Response to the following problem:
(a) Take the DCT of the Sinan image and plot the average squared value of each coefficient.
(b) Circularly shift each line of the image by eight pixels. That is, new_image[i, j] = old_image[i,j + 8| (mod 256)]. Take the DCT of the difference and plot the average squared value of each coefficient.
(c) Compare the results in parts (a) and (b) above. Comment on the differences.
