In tests, volunteers were asked to identify people from the standard photofit of their face and from their caricature.On average, a photofit face was correctly identified 20% of the time, compared with 40% for the caricature, according to a report in this month's Visual Cognition journal.
In a second test, the team led by Charlie Frowd asked volunteers to make photofits of international footballers two days after being shown a picture of them. The delay was introduced to reflect the typical amount of time that passes from a crime being committed and a witness being asked to create a photofit.
When the images were shown to volunteers, only 3.4% of them were correctly identified, a similar success rate as that reported for police photofits. The researchers are in discussions with police over the possibility of trying out the technology after future crimes.

Caricatures better than Police Sketches
Interesting. When I've seen a police sketch and the person they identified with it, I can almost never see the resemblance. [Link]
