Scientists Create 3D Time-Lapse Videos from Internet Photos of Landmarks

Comment

Researchers at the University of Washington have figure out how to create 3D time-lapse video sequences of landmarks by using a collection of still photos found on the Internet. The 7-minute video above is a short presentation that shows the technology in action.

Unlike previous work in this field, which assumed a static camera (the scientists shared their earlier progress back in May), this project uses a virtual camera that is able to move around continuously through time and space as the time-lapse plays, providing an extra dimension of depth and immersiveness for the viewer.

Each video is created by generating a “time-varying depth map” of the scene and building a high-quality hole-free image of the scene for each of the frames using data gathered from the still photos. The resulting time-lapses are able to show how various skylines and natural landscapes change over the years, displayed with “dramatic parallax effects.”
