Wonderful, something else to encourage people to hang out on street corners. Maybe they could make little plastic pistol holsters. Well, at least the garbage will be closer to eye level now.
I wonder how expensive this algorithm is. Seems like it's going to take quite a lot of processing power, what with averaging gradient density & calculating a gradient path. That would put it out of range of, say, an iPhone dynamically retargeting an image to its preferred size. (Until processors are crazy fast anyway.)
But this technique is a shoe-in for image editing (photoshop / gimp / etc).
