Note that this exercise is intended to be solved by hand, without the use of computation.

Consider the following 7 images (labeled 1 through 7):

1 2 3
 
4 5 6
 
7

Each of the following 7 images represents the magnitudes of the DFT coefficients associated with one of the above images. We have labeled the transforms as A through I):

A B C
 
D E F
 
G

Which transform matches with each image? Enter a sequence of letters in the box below. For example, entering GDIC... would imply that G matches with 1, D matches with 2, I with 3, C with 4, ...
