Image analysis and graphics synthesis can be achieved with learning techniques using directly image examples without physically-based, 3D models. In our technique -- the mapping from novel images to a vector of pose and expression parameters can be learned from a small set of example images using a function approximation technique that we call an analysis network -- the inverse mapping from input pose and expression parameters to output images can be synthesized from a smallset of example images and used to produce new images using a similar synthesis network. The techniques described here have several applications in computer graphics, special effects, interactive multimedia and very low bandwidth teleconferencing.
