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 injury and an overlay production method to improve the comparison between the dentition of a suspect and the image of the injury. A comparison method entirely within the digital image software is also illustrated. The use of digitally-produced overlays appears to provide a more objective method of comparison. The use of this method for shoe print, tyre mark and other blunt instrument injury analysis is noted.
