State of the art biomechanical models of the face have shown promise in animation, but they are inadequate for the purposes of craniofacial surgery simulations. The goal of this work is to develop an improved face model, using Cyberware data that captures the external structure and appearance of the face and computed tomography (CT) data which captures the internal structure of the facial soft and hard tissues. We have developed algorithms to (1) register CT and Cyberware datasets, (2) extract from the CT data a skull subsurface which serves as a foundation of the soft-tissue model, and (3) compute the thickness of the skin. More information about this project is available in my masters thesis.
The following figure illustrates the steps of the facial model construct process.
