New model for image segmentation, motion tracking and more

This is a cool site I found that shows an algorithm that can segment, or cut out, an object in an image. If you've ever used photoshop you know this is a recurring and often time-consuming task. Not only can this algorithm "cut out" objects within pictures automatically, but it can also be used for motion tracking and more complex applications. I've included the webpage here, along with just a couple of the demo videos on the site which show how it works.
