Privacy and security are a really important facet of any business. Every business owner wants their assumptions as safe and secure as possible without any unwanted visitors roaming around the premises. Every government security agency is using facial recognition software to track down criminals and outlaws. Cosmetic Dentistry Technology has been widely used for different purposes and it’s about time people come to know more about this wizardry.
Facial Biometrics is a technology capable of identifying a person by scanning and reading certain facial features. Facial Recognition Technology has come a long way and now have various applications in mobile platforms, robotics and even matter of national security.
Various Techniques Used for Facial Recognition
Traditionally there are two different ways which are used for facial recognition.
1. These algorithms identify the faces by extracting the facial features from an image of the subject’s face. In this method, the algorithm analyzes the facial features like relative position, size, the shape of nose, ears, cheeks, lips etc..
2. Another way is to use a compacted probe image which contains all the required information to recognize the face of a specific person. The probe image is compared to the accessible face data to recognize the required face from the data pool.
In 3-dimensional facial recognition, 3D sensors are used to record the facial features with more details such as the structure of the contour, spots, shape of the eye socket, chin, nose . The extra benefit of 3D face recognition is that it’s not dependent on the light like the other procedures.
In this method, the facial features can be scanned in different lighting and a wide range of viewing angles. This method drastically increases the accuracy in the process making it more reliable and usable in various conditions.
There are some other methods used for facial recognition like:
Skin Texture Analysis
Applications of Face Biometrics
There are many mobile programs which use face recognition for different purposes. Snapchat uses facial recognition to add a new filter which may change the way you look. Similarly, there are lots of such mobile programs which use this technique to improve their services.
Various Police and National Security Agencies around the globe use facial recognition systems to monitor offenders and identify suspects.
In big companies and government agencies, various biometric machines and cameras are used to automatically mark the presence of employees or any particular individual.
