Facial conformation modeling via interactive adjustment of hierarchical linear anthropometry-based parameters

ABSTRACTThis paper presents a new and easy-to-use interactive facial conformation modeling method. The modeling of a specific face is performed on a generic, triangle mesh based face model by adjusting a set of hierarchically organized facial confirmation parameters, which are derived from the anthropometric data on human faces. The method transforms complex facial conformation mesh manipulations into simple linear parameter adjustments between the specified anthropometric landmark points on the face mesh. The parameter adjustments are made interactively via a three-level hierarchical framework. Geodesic distance based compactly supported radial basis functions are employed to smoothly interpolate the displacements of the face mesh vertices and facilitate localized deformation and hole handling on the face mesh. The involved linear anthropometry-based parameters are classified into three different levels with each level governed by its own radial basis functions. Simple and interactive mesh manipulations ...
