Crop images based on image entropy

[joeholdcroft]

It's plausible that Imagine might have some code to support this, but either way it'd be nice to crop images based on their entropy.

This blog post has a nice explanation.

Details on how they calculate it:

And here is an updated version of the lib:

Sure looks interesting and in my opinion not even that hard to implement if we wanted to do something similar and not use the above lib. Could even ask my image processing professor whether he's got other ideas for solving cropping problems.

Couldn't find any details on whether Imagine supports this, though.
