Ken Linge RFP BA. MSc. FBIPP
Facial mapping - facial imaging - pattern analysis -
CCTV analysis & identification - Forensic photographic expert

DABS Forensic's Ken Linge is registered with the National Police Improvement Agency (NPIA) and provides services to Police forces and defence lawyers throughout the UK. Ken has a Master of Science degree in Facial Mapping and is a former member of the Home Office Advisory Group to ACPO (Association of Chief Police Officers) on Facial Mapping, and was a member of the Home Office Working Group on Digital Imaging.

From the inception of CCTV security Ken Linge has been actively involved in the development of the science of Forensic Facial Identification by Image Comparison-known as Facial Mapping and has contributed to the development of new and existing Facial Mapping techniques, and working practices constantly testing the reliability and integrity of the evidence that has been submitted. Ken Linge been personally involved in over 400 cases in the past 14 years.

Facial Recognition Research

This work examines the whole field of facial recognition and identification with regard to Criminal Evidence, Image quality, CCTV systems, Biometrics, Probability Factors and the development of Computational Facial Recognition Systems. One of the key proposals contained within the thesis is that any recorded image linked with a crime, is formed by trace material (photons), and should therefore be regarded as a forensic mark.

The projects with which Ken Linge is currently engaged are an extension of the work of Wilcox et al who devised the Face Feature Database-Home Office-1996. This involves researching the frequency analysis of feature types within the various face types therefore having a deeper knowledge of the all important probability factors.

A further project is an examination of the reliability of correlation of feature points and the flawed assumptions that can be made when these are measured in isolation.

Forensic Experience

Ken Linge been a professional forensic photographer for over forty-five years of which twenty-nine were with the photographic department of Essex Police. Ken was the Department Head for 16 years that allowed him to gain valuable experience in the various applications of imagery as an aid to criminal investigation. He also trained Scenes of Crime Officers in photographic techniques.

In 1989 he was awarded a fellowship of the prestigious British Institute of Professional Photography(FBIPP) recognised by the photographic industry throughout the world.

Other experience acquired includes the lesser-known aspects of the forensic photographic field that include invisible radiation (UV/IR), on which he is an authority, together with image analysis/photographic interpretation, photogrammetry and contemporary technology facilitating image enhancement and forensic pattern matching (weapon to injury).
