EvoFIT: A holistic, evolutionary facial imaging technique for creating composites

Frowd CD, Hancock PJB & Carson D (2004) EvoFIT: A holistic, evolutionary facial imaging technique for creating composites, ACM Transactions on Applied Perception, 1 (1), pp. 19-39.

EvoFIT, a computerized facial composite system is being developed as an alternative to current systems. EvoFIT Faces are initially presented to a witness with random characteristics, but through a process of selection and breeding, a composite is ‘evolved’. Comparing composites constructed with E-FIT, a current system, a naming rate of 10% was found for EvoFIT and 17% for E-FIT. Analysis revealed that target age was limiting factor for EvoFIT and a second study with age appropriate targets visible during composite construction produced a naming rate similar to E-FIT. Two more-realistic studies were conducted that involved young target faces and 2 current systems (E-FIT and PROfit). Composites from both of these experiments were poorly named but a significant benefit emerged for EvoFIT.
