A very simple version of this can be accomplished, by using a live camera input (you may need to play with back vs front lighting).

Then applying a Threshold actor (to create a black and white only version of the video input). Then the Edge actor (this will trace the edge between the white and black) providing the outline.

You can then send this outline/shadow to any outputs and/or mapping you like.

Skulpture, I think that the GPU really did the trick. Either that, or a combination of better lighting and brighter clothing made the effect go away. Thank you all for your responses!
