Mobile Face Detection
Face Localizer on a Nokia N95
A plethora of face detection techniques have been proposed, However, the application of these techniques to mobile devices, such as mobile phones, raises several challenges because of two issues: the inefficiency of the algorithms and the limited processing capabilities of the mobile devices.
Recently, we improved the efficiency of a face localisation system to operate on a mobile device by changing the underlying scanning process and by converting all floating point arithmetic to fixed point arithmetic adequately.
We were able to run the same optimized algorithm on 3 different devices: a Nokia N95 (see the above video), a Nokia N93i and a Nokia N810 (see the video below).
