“…The facial image anthropometry is quantitative analysis based on indices calculated from measurements of facial dimensions 2,3,14,32,34,35) . In order to directly assess the two facial images, the video superimposition technique has been applied to the facial image comparison 3,5,26,27,36) . However, this latter technique requires that the facial image of suspects be taken in exactly the same orientation as the facial image at the crime scene.…”

This paper reviewed recent advances in facial image identiˆcation from the forensic aspects. Although literatures reviewed included mathematics and computer engineeringˆelds, anthropological techniques were mainly described. Facial image identiˆcation is generally attempted using three methods: morphological comparison of facial features, facial image anthropometry and face-to-face superimposition. The most commonly employed method in actual caseworks is morphological comparison based on surface anatomy, followed by anthropometrical analysis and then face-to-face superimposition. The current technique using a 2D/3D facial image superimposition was introduced and its advantage and disadvantage were described. The evaluation of reliability in facial image identiˆcation including expert opinions was discussed, along with some problems of facial images submitted as evidential samples.

“…A more developed version of the composite face technique, video superimposition (or video wipes), can also be employed to demonstrate facial similarities and differences in a legal context (e.g. R v Ciantar, 2005, R v Clarke, 1995, Vanezis & Brierley, 1996, Oxlee, 2007. In this technique, one image is superimposed on top of the other, and the display gradually 'wipes' between the two.…”

Facial image comparison by video superimposition Facial wipes don't wash: Facial image comparison by video superimposition reduces the accuracy of face matching decisions AbstractIn cases of disputed CCTV identification, expert testimony based on the results of analysis by facial image comparison may be presented to the Jury. However, many of the techniques lack empirical data to support their use. Using a within participants design, we compared the accuracy of face matching decisions when images were presented using a 'facial wipe' technique (where one image is superimposed on another, and the display gradually 'wipes' between the two), to decisions based on static images. Experiment 1 used high quality image pairs, Experiment 2 used disguised target images, and Experiment 3 used degraded target images. Across all three experiments, rather than optimising performance, facial wipes reduced accuracy relative to static presentations. Further, there is evidence that video wipes increase false positives, and therefore may increase the likelihood that images of two different people will be incorrectly judged to show the same individual.

“…Similarly, if the head is tilted backwards, the chin will appear larger than the forehead [37]. However, some research suggests that it is possible to do facial mapping between similar face angles even though the exact angle is unobtainable [38] and the acceptable threshold of face angle variation is expert dependent [37,38]. This study utilised photogrammetry in order to compare the normal and bloated faces.…”
