Anybody tried entropy cropping?

Seems like this might be a nice way to auto-crop.

Interesting approach

But no guarantee that the region with most details (edges) is actually the thing you want to crop.

Good point, but I wonder if you could narrow it down to types or subjects that work well with this style. Macro photographers might really benefit, for example.

Thanks for the link, this really is an interesting approach. The idea is quite simple, but I've never seen this implemented and it really makes sense to me.

I can imagine that this would make a great addition to apeisas great Thumbnail module. This behavior might lead to a more sensible default crop than just cropping from the center. It would have to be optional though, ideally on a per Field basis, because as already pointed out, it may not make sense for all types of images and I also think that it might use up quite a lot of resources on the server.
