3D-ID: Geometric Morphometric Classification of Crania for Forensic
Scientists
***
Dr. Ann Ross of North Carolina State University, USA and I would like to
announce the availability of a new program, 3D-ID, for the forensic
anthropology community.
The program and documentation can be found at:
http://www.3d-id.org
3D-ID was developed with support from the U.S. National Institute of
Justice (grant 2005-MU-BX-K078 to Ann Ross). It is designed to use
geometric morphometric methods to aid in the characterization of human
cranial remains.
The user provides the three-dimensional coordinates of available
landmarks from an unknown cranium, and the program compares that
configuration to matching populations drawn from a reference database of
over 1000 individuals of known sex from eight populations. Suggested
assignment is based on Mahalanobis Squared Distance and diagnostic
statistics (posterior probabilities and typicalities) are presented.
Cross-validation analysis shows for this reference data and a given sex,
correct classification to one of the eight relevant populations is
80-85%, while within, for example, the European-Americans, correct
identification of sex can approach 90%.
Limited use of the program in applied, research, and educational
situations is free of charge. See documentation for details.
The program is written in Java and will run on any system on which Java
SE 5 (Java version 1.5) or greater has been installed.
Serious users are advised to look carefully at the composition of the
current reference sample to gauge its appropriateness for a particular
application - the reference material is not evenly distributed across
populations. Future versions are expected to expand and diversify the
available reference data.
