This is an experiment (a prototype in Blender) of a new feature we are developing in our makehuman software. It's a new, original next-gen tool, that automatically models the most probable realistic head. So the user needs just a few clicks to roughly set the most important facial features, and makehuman will do the rest of the work :-)
Actually we have a limited DB at the moment, so the results are still limited.
In this example, we use it to repair a bad modeled head. (less info)
