This video has been making the rounds the past couple weeks. It is a demonstration of dynamic image resizing. Normally when resizing an image, you will get artifacts with making it either larger or smaller. This demo shows a method of making an image resizable by stretching the unimportant parts of an image and keeping the important parts (faces and primary objects the same). I can’t wait till this gets put into real software that I can get my hands on. I think this would work very well in fluid web layouts.
I think the video speaks for itself.
