MovieReshape Software Changes Body Shape of Actors in Videos

You too can have a dream body – in your movies - New Scientist

Tweaking someone's height and weight on film has till now been a laborious frame-by-frame business – but new software makes it easy

 Developed by Christian Theobalt of the Max Planck Institute for Informatics in Saarbrücken, Germany, and colleagues, it allows professional and amateur movie-makers to dramatically alter how muscular, leggy or heavy people appear on film. Until now this could only be done by laborious frame-by-frame retouching.

The software, called MovieReshape, builds on existing programs that track an actor’s silhouette through a scene, mapping the body into a morphable model. Using the compiled 3D scans, the program can create realistic-looking and moving body parts to the programmer’s specifications. The more dramatic the alteration, the more noticeable it may be against a constant background, but in a survey of 30 viewers, none reported the distortions to be distracting.
