Contemporary developments in three-dimensional 3D digitised image capture, graphical modelling and animation have begun to impinge on some quite traditional areas of the forensic sciences. Forensic facial reconstruction serves as a case in point, but surveying and reconstruction and modelling and animation of accident or crime scenes are other fields in which 3D computerised methods are gradually being adopted. In this article, I would like to concentrate on 3D facial reconstruction, briefly describing the traditional method, and outlining the novel approach being adopted in the computerised 3D forensic facial reconstruction project at the University of Sheffield.
This unique books looks at a cost-efficient, fast and accurate means of facial reconstruction--from segmented, decomposed, or skeletal remains--using computer-graphic and computational means. Computer-Graphic Facial Reconstruction is designed as a valuable resource for those scientists designing new research projects and protocols, as well as a practical handbook of methods and techniques for medico-legal practitioners who actually identify the faceless victims of crime. It looks at a variety of approaches: artificial intelligence using neural networks, case-based reasoning, Baysian belief systems, along with a variety of imaging methods: radiological, CT, MRI and the use of imaging devices.

Identification of human remains has been a major problem for the medicolegal system. Thousands of people every year are buried with their identity and that of their killer unknown. Mass murders have been committed in many parts of the world, e.
After human bones and skulls of unidentified individuals undergo CT scans, forensic artists use imaging software to re-create what a person may have looked like. During a murder investigation, sometimes all that surfaces are human bones. At the National Center for Missing and Exploited Children NCMECforensic imaging specialists are tasked with re-creating an image of what a child may have looked like based on skull and bone remains that surface during police investigations.

Vanezis, Maria Forensic facial reconstruction using 3-D computer graphics: evaluation and improvement of its reliability in identification. PhD thesis, University of Glasgow. This thesis is concerned with computerised forensic 3-D facial reconstruction as a means of identification and involves the restoration of the face on the skull in an attempt to achieve a close likeness of the individual when alive. The reconstruction process begins with the biological identification of the skeletal remains, age, sex, ancestry and build.
This is a brief overview of how forensic 3-D manual craniofacial reproductions are done. While this instructable will show the process of one case from beginning to end, it is not intended to be a proxy for teaching the knowledge and skills required to perform a credible facial reproduction; that takes years of training.

Facial reconstruction is a technique that aims to reproduce the individual facial characteristics based on interpretation of the skull, with the objective of recognition leading to identification. The aim of this paper was to evaluate the accuracy and recognition level of three-dimensional 3D computerized forensic craniofacial reconstruction CCFR performed in a blind test on open-source software using computed tomography CT data from live subjects. Four CCFRs were produced by one of the researchers, who was provided with information concerning the age, sex, and ethnic group of each subject.
