Skin Aging Estimation by Facial Simulation

We propose a layered facial simulation model for skin aging with wrinkles, which includes muscle, connective tissue and skin layer. Our aim is to simulate relevant facial animation and aging with the guidance of general facial tissue anatomy, so that the model can be extended to medical and cosmetic applications. B-spline muscle patches are automatically adapted to each individual face by mapping the anatomical facial muscle image. Connective tissues are simulated as simple springs with the length of hypodermis thickness that constrain skin movement. Facial skin deformation and aging are estimated based on an elaborated biomechanical model considering large strain deformation and wrinkle formation. Finally, multi-layered color and bump texture mapping are used to represent wrinkle forms and to render an aged face.
