The video is a presentation from the SIGGRAPH conference and describes new research in automatic image resizing. Know how your web pages reflow if you resize the window? Imagine if the same thing happened to your images, but without distortion. The presenter explains the algorithms they use to do the resizing. Very fascinating stuff!
