256x256 - Looks about the same as the 512x512 image...
128x128 - We are starting to notice some blurring in the image
64x64 - The lady is not recognizable anymore, along with most objects
in the picture.
128 grays - No noticeable difference
64 grays - We still don't notice much of a difference, this may be because
it is such a dark image already.
32 gray - Starting to notice a little bit of false contouring on her
16 gray - The false contouring is now more obvious.
8 gray - Objects are starting to lose their definition. Noticeable
on the lady's hand, and the phone.
4 gray - Now the image looks like it is from the 1980s of computing
2 gray - It is hard to figure out what is in the image without previous
knowledge of what it is. It is interesting that the credit card name
and number are still readable.
Matlab Code: [X, MAP] = tiffread('mot.512x512.tiff'); imshow(32 * log10(1 + abs(fftshift(fft2(X)))), MAP);
