Five genes found to determine face shape | TG Daily

DNA evidence could soon be enough to help law enforcement draw up photofits of criminal suspects, thanks to a new genetic discovery.

Five genes have been found to determine human facial shapes, says an international team.

"These are exciting first results that mark the beginning of the genetic understanding of human facial morphology," says professor Manfred Kayser from the Erasmus University Medical Center in the Netherlands.

BBC News - Genes for face shape identified

MRI images were used to quantify the metrics of face shape ahead of the genetic study

Lead author Manfred Kayser from the Erasmus University Medical Center in Rotterdam, the Netherlands, said: "These are exciting first results that mark the beginning of the genetic understanding of human facial morphology.
"Perhaps some time it will be possible to draw a phantom portrait of a person solely from his or her DNA left behind, which provides interesting applications such as in forensics."

Facial Shapes Outlined With Five Genes - Science News - redOrbit

In the study, published in the Public Library of Science’s journal PLoS Genetics, Kayser and colleagues studied nearly 10,000 individuals, using magnetic resonance imaging (MRI) of their heads together with portrait photographs to map facial features, from which facial distances were estimated. They then conducted a genome-wide association (GWA) study designed to search for small genetic variances that occur more frequently in people with particular facial types.

Using these methods, the team was able to discern five separate genes associated with facial shapes: PRDM16, PAX3, TP63, C5orf50, and COL17A1.

New Advanced Surveillance Camera System

New surveillance camera can search 36 million faces for matches in one second

(PhysOrg.com) -- A new surveillance camera by Hitachi Kokusai Electric can look at footage that contains an image of someone, either still or video, and then search other video or still images on file for other instances of that same face. In so doing, it can search, process and display up to thirty six million faces in just one second. Each hit is displayed immediately in its native format, i.e. still or video, in thumbnail form, which its makers say, allows the camera to display the actions of a person prior to, or even after, being seen by the surveillance camera. All they need do is click on the thumbnail to watch the video play.

The search results are displayed immediately, showing thumbnail images of potential candidates. When a thumbnail is selected, the associated recorded surveillance footage can be viewed, so users can quickly review the persons actions before and after the image was taken.

"This high speed is achieved by detecting faces through image recognition when the footage from the camera is recorded, and also by grouping similar faces."
With this system, it's assumed that faces are turning within around 30 degrees in the horizontal and vertical directions from the camera, and the faces are at least 40 x 40 pixels in size.

"We think this system is suitable for customers that have a relatively large-scale surveillance system, such as railways, power companies, law enforcement, and large stores."

Moving pictures are more suitable to interpret facial expressions

clipped from www.sciencedaily.com

A Facial Expression Is Worth a Thousand Words
[...] Scientists from the Max Planck Institute for Biological Cybernetics in Tübingen, Germany, found out that we are able to recognize facial expressions in motion -- for example, in a movie -- far better than in a static photograph. The video sequence needs to be at least as long as one tenth of a second to gain this dynamic advantage.

Interpreting this facial expression correctly (as a "baffled" expression) is very difficult based on this photo alone. When showing the corresponding video sequence, however, recognition becomes easy, which underlines the importance of the temporal dimension for effective communication.

Forensic Molecular Photofitting

DNA Aids Forensic Experts

US scientists report that the smallest amount of DNA found at a crime scene could help reveal the face of the criminal.

The new process called ‘forensic molecular photofitting' goes far beyond doing an identity-proving genetic fingerprint.

DNA sample may be enough to build an image of your face

FORENSIC SCIENCE is about to take a startling new turn – reconstructing facial features and skin tone simply by reading your DNA. This goes far beyond doing an identity-proving genetic fingerprint, it means the person’s actual face will emerge after analysing a collection of genes, according to a scientist from Pennsylvania State University.

The process has already been used to help identify and convict serial killer Derek Todd Lee who murdered seven women in Louisiana.

Witness statements said the offender was white but genetic testing of DNA at the crime scenes showed he was African American - which helped lead to his arrest.

He was convicted in 2004.

Mark Shriver, an anthropologist and geneticist at Pennsylvania State University, has also set himself a daunting challenge: Trying to construct a "picture" of a person's face by analyzing DNA. He calls the technique "forensic molecular photo fitting," and it is supported by a $500,000 grant from the U.S. Department of Justice.

His team collected DNA samples and photographs from 243 people, including many from the Penn State campus, and used computer techniques to correlate the genes with his subjects' facial features. They have found six genes that seem to influence such traits. One gene is associated with the height of the face; another is associated with its width. Yet another gene affects the shape of the lips and the nose. By piecing together these elements, Prof. Shriver hopes to create a modern-day version of the police artist sketch.

Einstein Robot - UCSD Machine Perception Laboratory

Scientists at UC San Diego's California Institute for Telecommunications and Information Technology (Calit2) have equipped a robot modeled after the famed theoretical physicist with specialized software that allows it to interact with humans in a relatively natural, conversational way. The so-called "Einstein Robot," which was designed by Hanson Robotics of Dallas, Texas, recognizes a number of human facial expressions and can respond accordingly, making it an unparalleled tool for understanding how both robots and humans perceive emotion, as well as a potential platform for teaching, entertainment, fine arts and even cognitive therapy.

Introducing the scarily realistic Einstein robot who can tell how you feel

With a big bushy moustache and a shock of white hair, scientists have modeled an ultra realistic robot on Albert Einstein. [...] Using specialised software the machine can recognise and respond to a number of human facial expressions in a natural way.

Clipped from: Calit2 : It's All Relative: UC San Diego's Einstein Robot Has 'Emotional Intelligence'

"In the short-term, Einstein is being used to develop computer vision so we can see how computers perceive facial expressions and develop hardware to visually react," says Javier Movellan, a research scientist in the Calit2-based UCSD Machine Perception Laboratory (MPL). "This robot is a scientific instrument that we hope will tell us something about human-robot interaction, but also human-to-human interaction.

"When a robot interacts in a way we feel is human, we can't help but react. Developing a robot like this one teaches us how sensitive we are to biological movement and facial expressions, and when we get it right, it's really astonishing."

[...]

Another important part of the robot's inner workings is its Character Engine Artificial Intelligence Control Software, which allows the programmer to author and define the persona of the character so it can hold a conversation.

"Einstein has pretty broad conversational abilities, although not like a human," Hanson notes. "In the demo mode, he might say something like, 'I'm an advanced perceptual robot bringing together many technologies into a whole that's greater than the sum of my parts, but here's what some of my parts can do. I can see your facial expressions and mimic them. I can see your age and gender. So why don't we demo some of these technologies?'"

Einstein Returns As A Robot

The robot can recognize and mimic 5,000 facial expressions and is powered by 31 motors and innovative new technology. The Einstein robot could be the next big thing in the world of engineering.

Javier Movellan, a professor at the college, says: "The best expressions that it can recognize right now are expressions of sadness and happiness."

Movellan adds, "You know that children with autism have problems recognizing facial expressions and producing facial expressions in social communication. So we're trying to see whether this robot will actually be useful and helpful to teach children with autism how to communicate with human beings."

Scientists hope to use the technology to improve the way computers relate to people.

A beauty machine 'that makes average face a knockout'

Washington (PTI): Researchers have built what they claim is a beauty machine that, with just the press of a button, can turn a picture of an ordinary face into that of a cover model.

"Beauty, contrary to what most people think, is not simply in the eye of the beholder. With the aid of computers, attractiveness can be objectified and boiled down to a function of mathematical distances or ratios.

"This function is the basis for the beauty machine," lead researcher Prof Daniel Cohen-Or of Tel Aviv University's Blavatnik School of Computer Sciences said.
