Recent Advances in Facial Image Identification

Abstract

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.

Assessment of some problematic factors in facial image identification using a 2D/3D superimposition technique

“…Therefore, identification between the facial image taken with a surveillance camera at the crime scene and mug shots of suspects increases, too. In general, the following 3 approaches to facial image identification are used: morphological comparison of facial features (facial outline, eyebrows, eye, nose, lip, and ear) [1][2][3][4], anthropometric analysis [2][3][4][5], and face-to-face superimposition [3,4,[6][7][8][9][10][11][12][13][14][15].…”
