A group of researchers has built a way to mine the giant corpora of pictures people have posted publicly (on sites like Picasa and Flickr) and build time-lapse images of landmarks. This involves huge technical challenges of identifying landmarks, building 3D models of them, stabilizing the images, and normalizing the motion and lighting -- and so far, they've managed to find over 20,000 such images, showing everything from changing seasons, to building construction, to moving glaciers.
They've made a video showing off their favorites: https://youtu.be/wptzVm0tngc
. You can read the paper at http://grail.cs.washington.edu/projects/timelapse/
, and hopefully they'll soon have a way to see all their results.
