Computer assisted 3d craniofacial reconstruction Bullock, William David
Abstract
This thesis describes a methodology for forensic craniofacial reconstruction, denned as the reproduction a subject's facial appearance from the skull and mandible for the purposes of identification. The focus of this work is on reproducing three dimensional facial shape from the shape of the skull and mandible of a subject. This task can be broken into two parts. First, a technique for determining soft tissue depth at any point on the skull and mandible surface is presented. Second, two complementary methods of producing three dimensional facial shape are presented: a method which generates a surface using the skull and mandible as a skeleton of an implicit surface and a method which produces a hierarchical B-spline surface fit to facial surface locations. Surface material properties and facial features can then be added and modified to these models before being rendered and distributed. Results of these processes are presented.
