What makes a face attractive?

The concept that beauty lies in the eye of the beholder, has received significant attention over the past few decades. We are born with an innate ability to perceive faces and babies can recognize facial attractiveness by the age of 5 months. (Geldart et al 1999)

The speed and accuracy with which humans both recognize and judge faces remains one of the most sophisticated fruits of evolution. The quest to understand and replicate the precision of human facial recognition is of great interest to the biometric technologists and the security industry. This same process of teaching a computer to analyze a face may potentially be used to determine which faces we may also find attractive.
