Detecting Facial Bone Structure Biometrics in Iceland
Detecting Facial Bone Structure BBC News is running a story on the airport face-off (related thread) that is taking place in Iceland's main airport: Smile For the Computer. It looks into one company in the duel, Visionics. Apparently, their software extracts the bone structure from a given face by estimating the position of about 80 points. Of course, this is done more or less precisely based on the angle of view or the weather conditions; this is done by a machine vision algorithm. The identification algorithm only needs a few of those points to match a face stored in a database, so I'm assuming there's some dimensional reduction going on behind the scenes. Essentially, the properties of the 80 points extracted are reduced to a smaller number of attributes -- removing the reduncancy. I expect a nearest neighbour search is then performed, but that's just reading between the lines... I could be wrong! | Alex J. Champandard 931 posts. Friday 15 March, 09:53 Reply
