"MY TWIN did it" might seem like the perfect defence, but it won't work for much longer. A computer program that can pick out small differences in identical twins' facial features as they age can distinguish them 90 per cent of the time.
Kevin Bowyer of the University of Notre Dame in Indiana, whose research group created the data set used to test the differences between twins, says techniques to distinguish twins could help train forensic examiners in facial recognition. Because a twin-detecting algorithm needs to be precise, it could also lead to algorithms that are more accurate for all faces, he says.
