The Philter

“Mind-Blowing Photo Editing Technique of the Day: Kevin Karsch and his team at the University of Illinois Urbana-Champaign have developed an amazing technique for inserting synthetic objects into old photographswith lighting and positioning so close to the real thing that most people can’t tell the difference.

The method requires very little information to work well. Users just have to adjust the system’s guesses about vanishing points and scene corners, and then mark light sources in the image. With a few minutes’ work, even a novice user can insert (and even animate) realistic-looking objects.

The UIUC team will present their research at the SIGGRAPH Asia computer graphics conference in December.
