The construction of a composite by selecting individual facial features is common practice in criminal investigations. Photofit, identikit, efit and other ‘feature’ systems are old-fashioned and results are usually ineffective when used to identify suspects. This is why EvoFIT was developed.
Current practices may build composites with a single face, but operating on only one face means that a witness must continuously describe changes necessary to improve the likeness. This “recall” process is a naturally hard task for anyone to do. Recognising a face, on the other hand, is fairly easy and accurate. EvoFIT therefore attempts to tap into witnesses’ recognition rather than recall.
