Computer-aided forensic facial reconstruction.

The reconstruction of facial features on the human skull for identification purposes has, in the past, utilized either two-dimensional drafting or three-dimensional sculpting techniques. We have developed two- and three-dimensional computer-aided routines to minimize errors introduced by limits of artistic ability or by inconsistencies in the application of techniques. These routines allow generalized facial features to be manipulated to conform to the size and shape of a specific skull. Subtle alterations of the surface form, texture, and color, based on age, sex, and race, enhance the individuality of the generated facial form.
