Eye reflections in photos could catch child abusers

eye_reflections_quikrpostReflections in the “dark mirror” of a person’s pupil could be used by police to identify criminals, piece together crime scenes or link networks of suspects.

An experiment by the University of Glasgow’s psychology department found that zooming in on high-megapixel images can capture recognisable images of the person taking the photo and other people nearby.

Even though the zoomed-in images were only 27 to 36 pixels wide, the study’s 32 participants could still reliably identify the face, according to the findings published in the PLoS ONE journal.

“For crimes in which the victims are photographed (e.g. hostage taking, child sex abuse), reflections in the eyes of the photographic subject could help to identify perpetrators,” researchers Rob Jenkins and Chistie Kerr said.

“One possible extension of this technique would be to combine pairs of images recovered from the subject’s two eyes.

“In principle, these images contain the stereo disparity information required to reconstruct a 3D representation of the environment from the viewpoint of the photographic subject.”
