The Development of a Wireless Electrostatic Mark Lifting Method and its use at Crime Scenes
Robert Milne and Grahame Sandling, CSI Ltd

CSI Ltd have two areas of interest. The first is to do with materials involved in a technique called electrostatic mark lifting, which was demonstrated during the seminar.  The second involves pattern recognition.  See presentation below..

CSI Ltd produce their own footwear evidence software called Treadmark, which currently has the latest UK beta version working very well in the Leicestershire Constabulary which has the best footwear evidence detection rate in the UK. The software stores footwear marks and scans of suspected offenders shoes for measurement comparison and overlay enabling the ease of handling of the evidence type for screening. The software connects on line to the National Police Improvement Agency's (NPIA) National Footwear Reference Collection (NFRC) of over 19,000 reference records from anywhere on the internet. We began to look at machine vision and Treadmark can for zigzag patterns search on wavelength, amplitude and periodicity but we seek to improve on this basic approach and see a considerable market in effective automatic pattern recognition not only in our application but in many other areas.

CSI Ltd has produced a students (Colleges) version of Treadmark (one licence for 5 stand alone computers) in modern 64 bit format ready for market so that students of forensic science can actually use software actually used by police services and access the NFRC. The stand alone licence version can however communicate with other stand alone's or Treadmark in networks by prior arrangement. In this way small police services can afford a system and be networked without the expense of actually having a server based licence designed for larger organizations or states.
