THE USE OF A DIGITAL IMAGING TECHNIQUE TO AID BITE MARK ANALYSIS

Criminal cases occasionally involve the analysis of bite mark injuries . This paper presents a method of digital image enhancement of an inju ry and an overlay production method to improve the comparison between the dentition of a suspect and the image of the injury. A comparison m ethod entirely within the digital image software is also illustrated. The use of digitally-produced overlays appears to provide a more objec tive method of comparison. The use of this method for shoe print, tyre mark and other blunt instrument injury analysis is noted.
