Finding your friends through their outfits

One of the first apps developed specifically for Google Glasses ,InSight can pick user's friends out of the crowd , even when their faces are hidden. Co-funded by Google and developed by Srihari Nelakuditi and colleagues at Duke University in Durham,North Carolina, InSight identifies a person from their 'fashion fingerprints' .Facial recognition systems already exist, and anyone with Facebook profile is reminded how accurate they can be each time they upload photos to the site, but facial recognition systems only work when the face in question is looking directly at camera. InSight records the patterns ,textures and colors of clothing that someone is wearing and uses that information to make identification so that when some one is wearing Google glasses headset looks around them, the app picks out that person's friends, and shows their name on the headset screen .In tests with 15 volunteers , its developers claimed that it is 93 percent accurate.
