New technique to make shaky cam videos stable

The kind of shaky handheld footage that is a hallmark of home movies has become popular with Hollywood directors in recent years. But new software means that handheld cameras need no longer give wobbly results.

Computer scientists at the University of Wisconsin, Madison, and software giant Adobe have developed a technique that mixes 3D reconstruction with optical illusion to turn distinctive wobble of handheld camera footage into the smooth glide of a Hollywood tracking shot.

The process starts using off-the-shelf software called Voodoo Camera Tracker that can reconstruct a camera's path through 3D space from a video sequence.

Using that as a reference, the software then tries to distort each frame to create the way things would have looked were the camera to have been on that perfect, smooth path. Rather like a fun house mirror, different regions of each frame are warped by different amounts.
