[MARCH-2018]
Facial Recognition:
In this, a user can unlock the smartphone just by looking at it. Many algorithms like colour segmentation, template matching, etc. for face detection and Eigen & Fisher face-for-face recognition are being used. The technology uses an infrared light that illuminates the face, and a projector projects an array of infrared dots at it. An IR camera snaps an image of these dots, which the phone uses to authenticate you against an already-stored image of your face. It builds a 3-D depth map of your entire face using a 30,000 point dot matrix. The system tracks a user’s face accurately even when the user is wearing glasses, a hat, in low-light conditions or with changes in beard.
