Seam carving, the new resizing and crop?

I ran into something interesting today as I was looking on the interwebs. a technique called seam carving, which is a algorithm that resizes and crops in a intelligent way.
it looks at which parts in the image are important and which parts contain less useful information and it scales(removes) that part of the image while preserving the important parts.

but I could talk about this in a lengthy way but i think its best shown with some example video’s:
