The identification of human remains in forensic cases is at best a problem, more so if the body is decomposed. Craniofacial identification problems have been successfully resolving by forensic investigators for more than six decades. During mid- 1980s and early 1990s some attempts were made to introduce an automated version of photo/video superimposition technique by a straight forward digital implementation of the original method. Skull/photograph superimposition is the most prevalent method by which unknown skulls are being identified, since a photograph of the suspected dead person can be easily obtained from the victim's family. According to Schimmler et al., who took eight measurements on a large sample of skulls, the chances are less than one in a billion that two skulls will be identical in these eight diameters. In order to perform a superposition, a maneuverable stand is needed to position the skull at exactly the same angle as the face in the photograph. The images of the skull and photograph are than digitally recorded and stored within the computer, and then both digitized images are superimposed on the monitor. The process of fitting the skull into the photograph is usually started by positioning the eyes in correct relation to the orbits. With the eyes correctly placed, the skull should then be in the proper position - it must not be broader or longer than the soft tissue on the photograph, and the chin, mouth, nose, ears and so on, should be in their correct positions. .
