Software Realistically Adds 3-D Objects to Old Photos

In this edition of The Full Spectrum, we interview Kevin Karsch, a computer science PhD student at the University of Illinois at Urbana-Champaign. He and his collaborators have developed a method for inserting synthetic objects into photographs without having access to the original location. By marking the rough physical geometry of the scene and the location of light sources within it, users can quickly add digital objects that behave as if they were in the original photo.
