All in the eyes: corneal reflections in photos can help solve crimes
Tuesday 31 December 2013 - 8am PST
The eyes are not just the mirror of the soul, they also mirror the world around us. Now, a UK team has found that today's high-resolution digital images are now so detailed, they can enlarge the eyes in people's photos and retrieve images of out-of-shot bystanders reflected on their corneas.
Combine this with the fact human beings are very efficient at recognizing faces, even from poor quality images, and you have the makings of a rich forensic resource for solving crimes.
In the past it would be reasonable to assume if you were the one wielding the camera, then you would not be in the picture.
But a new study published in the journal PLOS ONE is now turning this assumption on its head.
Lead investigator Dr. Rob Jenkins, of the Department of Psychology at the University of York, says:
"The pupil of the eye is like a black mirror. To enhance the image, you have to zoom in and adjust the contrast. A face image that is recovered from a reflection in the subject's eye is about 30,000 times smaller than the subject's face."

Researchers found that participants were able to identify the tiny faces of people reflected in the eyes of photographed subjects, findings which could help solve crime one day.

this tech could come in handy in dealing with terrorists filming something.
“...human beings are very efficient at recognizing faces...”
I never felt that was true of me. I think I’d recognize a photo of someone I know, but I remember looking at the “WANTED” posters in the Post Office and thinking, I could walk right past one of those guys and I’d never recognize him.
My grandmother used to say that she couldn’t tell if something was a drawing or a photo, and I’m not talking about super-realistic drawings either. I could never figure out if she was pulling my leg (a distinct possibility) or not.
Or maybe they can photoshop.
There was an old black & white, film noir, flick about this from early 50’s or late 40’s. Can’t remember the name of it, but that’s how they caught the culprit.
I have extremely limited ability to recognize faces. I’m very good with voices. I’m very good at recognizing people by how they walk. I can do body shapes pretty well. These are ways I compensate. But I’ve been known to walk down the sidewalk, look into a reflective window and not know that I’m looking at myself.
Speaking of reflections in corneas...
I remember that movie...they recovered the last
image on the deceased eyes.The killers face.
I was a kid at the time and thought..geeze.
The identity of the Ripper remains unknown.
Abbie on NCIS was doing this years ago.
“Im very good at recognizing people by how they walk.”
Yes, I do that too. I once recognized a gal I had worked with years before walking down the street behind her. But I gotta say, she had the ultimate “walk this way” sexy walk. I knew her immediately!
I’m glad to know I’m not the only one with limited facial recognition ability.
I remember that there was attemps by Scottland Yard to photographer the eyes of Jack the Rippers Victims in hopes of getting something to help them ID him. Of course photography has come a long way since 1888, but it’s amazing that this was concidered way back when.

And just adjust the depth of field and you can run right up the optic nerve into the brain, enabling you to see the images stored there.
Trouble is, they are not “Date/Time Stamped”.
This will not be difficult, because we all know with enough “sharpening” and calculation time, that a single pixel can reveal the bug splats on a liscense plate.
The Ripper was a fat, round black guy.
They used to think this in the 19th century. What’s old is new again!
