University of Bath scientists have developed a biometric system for identifying people based on their nose shape. The researchers used a photographic system called PhotoFace to scan the three-dimensional shape of volunteers' noses and used software to analyze them according to six main nose shapes. The researchers focused on the ridge profile, the nose tip, and the section between the eyes at the top of the nose.
The researchers say their system offers a good recognition rate and a faster rate of image processing than whole face recognition techniques. "The technique is able to achieve a level of detail that is beyond current competing technologies and can be extended to a myriad of other applications, ranging from industrial surface inspection to cosmetics," says University of West England professor Melvyn Smith.
The researchers plan to build a larger database of noses to test the software to see if it can identify individuals from a bigger group of people or from blood relatives.
