An efficient texture generation technique for human head cloning and morphing

Abstract

This paper presents a technique to efficiently generate a parameterized full-head texture from a single face image of the scanned data for modeling photorealistic 3D heads. We automatically register face scans in a database by deforming a generic head mesh to fit the specific person's face geometry with a volume morphing approach. After the face texture is transferred onto it, the 3D generic mesh is parameterized over a 2D texture domain to establish a correspondence between all the scanned textures. After having performed a vertex-to-image binding for all vertices of the head mesh, we automatically generate a full-head texture using color interpolation for unbound regions and weighted average splines for visual boundary removal. We also use a deformation method to extract ear textures from the input image for texturing individual ears. With the exception of the initial feature point selection, our method is fully automated. We show photorealistic and real-time head rendering and morphing with the resulting texture.
