Apple Files Facial Recognition Patent for iOS Devices
Apple has filed a facial recognition patent which details a practical security system for iOS devices, reports PatentlyApple. The system would be able to recognize your presence and face to quickly wake up your device and display your home screen without any touch input. It would also be able to operate at higher security level when needed, for example, when you're at work.
Apple outlines various methods that could be used to identify the user...
The reference model includes a reference image of a face, and processing the captured image further could include matching the eyes of the detected face with eyes of the face in the reference image to obtain a normalized image of the detected face. Additionally, processing the captured image could further include vertically scaling a distance between an eyes-line and the mouth of the detected face to equal a corresponding distance for the face in the reference image in order to obtain the normalized image of the detected face. In addition, processing the captured image could further include matching the mouth of the detected face to the mouth of the face in the reference image in order to obtain the normalized image of the detected face.
Figure 1 shown below illustrates a user walking up to an iPhone. The device recognizes the presence of the user, identifies the user, then transitions to a new state to acknowledge the user.
