Can hidden information in photographs be used to spot criminals?

Pupil images

Can the eyes of photographed crime victims help authorities spot their victimizers?

According to new research published Thursday in the journal PLOS One, high-resolution photographs can be "mined" for hidden information. Specifically, the authors said that photographs of faces can reveal enough visual information on bystanders to identify them.

In a small sampling of 32 study participants, test subjects were able to spot familiar faces reflected in the pupils of someone who was photographed 84% of the time, researchers said. When the reflected images were of unfamiliar people, observers were able to match the person to a second mug shot with 71% accuracy.
