Content Aware Image Resizing

Here's a video of an impressive new concept of image resizing. Instead of scaling down or cropping, it analyzes a photo for the most important elements in terms of the photograph, and slowly removes pixels from the insignificant areas for as long as the image needs to be shrunk down. Essentially you are left with a different photograph that sums up the most valuable parts of the original. This also allows for amazingly accurate ways of removing objects from the photo, by manually identifying unnecessary pixels, and allowing for the smooth evolution of the image. The video gets significantly more impressive as it goes along. Also here's a small demo available made by a third party (try the horizontal adjusting for more impressive results).
