I have 2 groups of images, and I want to compare these groups based on the spatial frequencies of the images. In the end, I'd like to be able to say "group A is/is not significantly different from group B based on spatial frequency" or something to that effect.
Can anyone think of a way to do this? This question seems to touch on the topic, but as far as I can see it doesn't provide the solution I'm looking for (particularly not for groups of images). MATLAB solutions would be the most valuable to me.
Thanks for any help!
