A Guide to Facial Recognition. 

Penry was the inventor of the 'Photo-Fit' technique of enabling witnesses to create accurate facial images which the British police adopted in 1970, a standard tool of the police for many years.

A facial composite is a graphical representation of one or more eyewitnesses' memories of a face, as recorded by a composite artist. Facial composites are used mainly by police in their investigation of (usually serious) crimes. These images are used to reconstruct the suspect's face in hope of identifying them.
