We won't go so far as to say that MovieReshape's human reshaping algorithm is the coolest thing we've ever seen, but it's pretty damn nifty. By crunching numbers obtained from a bunch of 3D models, MoveReshape is able to change people's on-screen attributes, making actors appear more muscular or taller, to name just two.

"The approach is based on a morphable model of 3D human shape and pose that was learned from laser scans of real people," MovieReshape's developers explain. "The algorithm commences by spatio-temporarily fitting the pose and shape of this model to the actor in either single-view or multi-view video footage. Once the model has been fitted, semantically meaningful attributes of body shape, such as height, weight, or waist girth, can be interactively modified by the user. The changed proportions of the virtual human model are then applied to the actor in all video frames by performing an image-based warping."

Sounds geeky enough, but you really have to see the algorithm in action to appreciate what's going on. Carve out about three and a half minutes of your time and hit the play button below. You'll be glad you did.
