Amazing image resizing

This image resizing technique is absolutely amazing. It is actually not only a technique to resize images, but also makes it possible to make objects (or people) in a picture disappear. What it does is basically take out parts of the image which it thinks are not important. The real difficulty obviously lies in finding the right part of the image to take out.
Once again an image (this time a video) is worth more than a thousand words. Check it out. Your jaw will drop.
