Researchers create time lapse videos by mining online photos

Researchers from the University of Washington and Google have synthesized time-lapse videos by mining large community photo collections.

We introduce an approach for synthesizing time-lapse videos of
popular landmarks from large community photo collections. The
approach is completely automated and leverages the vast quantity
of photos available online. First, we cluster 86 million photos into
landmarks and popular viewpoints. Then, we sort the photos by

stabilize the appearance of the sequence to compensate for lighting
effects and minimize flicker. Our resulting time-lapses show diverse
changes in the world’s most popular sites, like glaciers shrinking,
