  • Facial Recognition System


    Facial recognition systems are computer programs that are used for automatically identifying a person. Research on this technology started in the mid 1960s. This technology works by using several facial features in a person's image and comparing these with existing images in the database. Facial recognitions systems are used as an additional and mass security measure and are comparable to the other biometric security systems available today such as retina scanners, fingerprint scanners, etc.

    The Technology behind Facial Recognition Systems

    The first important factor in facial recognition systems is its ability to differentiate between the background and the face. This is especially important when the system has to identify a face within a crowd. The system then makes use of a person's facial features – its peaks and valleys and landmarks – and treats these as nodes that can be measured and compared against those that are stored in the system's database. There are approximately 80 nodes comprising the face print that the system makes use of and this includes the jaw line length, eye socket depth, distance between the eyes, cheekbone shape, and the width of the nose.Facial Recognition System

    Two-Dimensional Facial Recognition Systems

    Before the advent of faster computers and sophisticated imaging software, two-dimensional facial recognition systems were used. The problem that arose from this type of facial recognition system was the fact that the person to be identified must be facing the camera at no more than 35 degrees for accurate identification to be possible. Light differences and facial expressions also contributed to low accuracy in recognition of such systems.

    Three-Dimensional facial Recognition Systems

    The new facial recognition systems make use of three-dimensional images and are thus more accurate than their predecessors. Just like two-dimensional facial recognition systems, these systems make use of distinct features in a human face and use them as nodes to create a face print of a person. Unlike two-dimensional face recognition systems, however, they have the ability to recognize a face even when it is turned 90 degrees away from the camera. Moreover, they are not affected by the differences in lighting and facial expressions of the subject.

    Steps in Facial Recognition

    The first step in facial recognition is acquiring a real image or a two-dimensional image of the target. The system then determines the alignment of the face based on the position of the nose, the mouth, etc. After alignment, the system makes a facial template and proceeds to match it with the images in the database.

    Applications of Facial Recognition Systems

    Facial recognition systems have a wide range of commercial, government and military applications. Some examples of these are when the Mexican government made use of facial recognition systems to match their voters from their database to verify identity and minimize voter fraud. The system is also slated for use in airports to speed up identity verification processes and to increase security. The system can also be used in ATMs to ensure that the one making the withdrawal is the card's owner.

      Face Recognition System is a useful device for identity verification. It will ensure that identity theft never takes place. This technology has become mandatory for any premise with high security needs.
