Compiling Public Photos into Time-Lapses

Millions of photos are taken each and every day—many of them coming from the same scenic points at popular tourist attractions—and now, a team of developers from Google and the University of Washington have found a way to put those obligatory shots to use: through time-lapse imagery. By scanning image databases like Flickr and Picasa, the researchers were able to sort thousands of images by location and time and then collate them into seamless time-lapses. Drastic changes in landscape that would have gone unnoticed in individual photos are now beautifully revealed.
