De-aging High-Resolution 3D Facial Models by Example-Driven Mesh Deformation

Human face conveys significant characteristics of a person such as age traits and facial attractiveness. The absolute aesthetic value for human faces is still unclear; but meanwhile, facial attractiveness has been considered as cross-culture criteria. De-aging procedure on 3D model geometry can be used to enhance facial attractiveness due to improved shape analysis. We conclude our observation on aging progress into four rules: 1. drooping of eyelids, 2. lack of elasticity causing hollow cheeks, 3. slack on the middle face and 4. wrinkles. In this paper we present a framework to beautify (enhance facial attractiveness) realistic facial model by a mesh deformation method based on data-driven approach. For an elder input face, we extract the edges connected among feature points on the face mesh. The edge lengths are used as a feature vector, and an age score is associated with it. We search for a local minimum to obtain a related young vector and consequently maintain the similarity between the elder and young face. Once the young length vector has been determined, we can embed it to our new feature locations and then deform the model to a younger shape. The effectiveness of our work is to rejuvenate an elder face by altering the outline of a facial model.
