In a recently published study,
researchers demonstrated that people could be identified from pupil
reflections in photos, a technique that could be used to solve crimes. Dr. Rob Jenkins of the University of York
and Christie Kerr of the University of Glasgow presented participants
with enhanced, low-resolution images obtained from eye reflections in
photos. According to the study,
participants who were unfamiliar with the faces in the photographs were
able to identify them correctly 71 percent of the time, while
participants who were familiar with the bystanders’ faces identified
them correctly 84 percent of the time. Using similar techniques, crime
investigators could potentially identify perpetrators who photograph
their victims and also get clues as to the location the photograph was
taken. The full study is available to read on PLOS ONE.
