Initial Test Results of the Omron Face Cue Entry System at the University of Missouri-Rolla Reactor
The University of Missouri-Rolla Reactor facility is testing, in collaboration with Omron Transaction Systems, Inc., the Omron Face Cue facial recognition system for access control to its restricted area. The installation of this system is the first of its kind at a security-relevant facility in the U.S. And within the research reactor community. The Face Cue is an on-demand device based on facial recognition and storage technology. The image processing methodology is as follows: (1) facial position detection, (2) background elimination, (3) facial features discrimination via application of a wavelet transform. The extracted facial feature values are compared to the data archived in its database and access is provided upon meeting the authorization criteria. The current test phase consisted of assessing the functionality of the Face Cue during daily use and in terms of its robustness (flexibility) as a function of the following physical parameters: (1) subject's distance away from the Face Cue, (2) ambient lighting conditions, (3) subject's facial orientation, (4) subject's facial expression and (5) peripheral facial features/modifications. The system has operated at nearly 100% reliability during several test intervals with approximately 7,000 entry attempts to date.
