This is a demonstration of how to use Blender's tracking module to track a person's head without having to use any markers. As an example project a face mask is put onto an actor's head.
The sample footage is from the open movie Tears of Steel by the Blender Institute:    • Tears of Steel  Blender VFX Open Movie
