Google turned millions of public photos into timelapses showing how Earth changes


This is a brilliant way to use the millions of free public domain images that are just sitting around.

Researchers at the University of Washington and Google created more than 10,000 timelapsevideos using millions of free photos available online.

The team analyzed 86 million photos from social sites, including Flickr and Picasa, and grouped them into landmarks. Then they sorted them by date and “warped” individual photos onto one viewpoint, retouched them a little, and created a stop-motion video showing how a particular landmark has changed over time.

The videos were stitched together from completely unrelated photos, taken by different people, but they don’t look all that different from conventional timelapses. They do, however, reveal processes that would be hard to capture with a single camera, such as seeping water affecting a sculpture or waterfall streams emerging and drying up.
