United Kingdom scientists develop identification technology: scan nose identity

United Kingdom scientists developed through the nose for biometric technologies.

United Kingdom have found that in the confirmation of identity, scan the nose than with IRIS and fingerprint images faster and easier.

Fear of illegal immigration and identity theft, related departments are increasingly taking into account the personal characteristics of the body to confirm identity, the so-called biometric.

United Kingdom researchers say, the nose is different from the other used biometric facial features — such as the eyes or ears, the nose is difficult to hide and no because facial expression changes a lot. Bath University Dr. Adrian Evans and Dr. Adrian Moorhouse and decided on the nose of the image can be used to identify individuals.

Researchers with the University of the West of England and London Imperial College researchers develop "photo face" (PhotoFace) photography system scans the volunteers nose of three-dimensional shapes, and based on six main Napier, Roman nose, Greece nose, Nubian nose, flat nose, short Eagle upwards nose and down nose, use computer software provides an analysis of the nose.

In the analysis, the researchers do not use the whole shape of the nose, but instead uses three characteristics: nose profile, nose and nasal root, or top is located in the nose and eyes between parts.

They consider the nose of the radian, also use nose width and nose width and length of nose bridge, and then use this integrated proportional to distinguish between database of 36 individuals.

Researchers use a smaller sample size is found, with the nose scan for biometrics have great potential; and the whole face recognition when compared to traditional biometric technology, high scanning rate of recognition and nose and image processing speed.

Evans said: "my nose is a prominent feature of the face, but the role of biometrics in large part still remains to be explored.

We would like to clarify with the nose from the database, how to identify individuals. "He said," no biometric technology can solve all problems. Such as iris recognition although accurate, but it is difficult to accurately capture may also easily be eyelid or glasses shielding ... But to the nose it is much easier to take photos, and nose more difficult to hide, so if the object does not cooperate or secret surveillance, identification systems of the nose would be more effective. We only in small samples do test on, but it does show the potential that perhaps can be used in conjunction with other identification technologies. ”

Melvyn Smith Professor of the University of the West of England, led by team developed a "photo face" System.

He said: "with the collaboration of the University of bath is a very exciting project, this potential is huge. ' Photo face ' is an innovative 3D face data capture system, its principle is in several different angles of the Flash exposure photographs, so as to be able to very quickly took 4 entire face of continuous photos, each photo is in a different light conditions under the control of the shooting. ”

Smith said: "this technology is called photometric stereo measurement.

After the software can analyze each photo's shadow projections out colour, surface direction and face height for each point. This technology can achieve the exact level of more than a current and competitive with other technologies, and can be extended to all kinds of other applications, from industrial surface detection to the beauty industry. ”

The researchers then plans to build a larger nose database to test and improve the software, whether from a larger population identified individual, or the ability to distinguish the various relatives of the same family.
