Privacy and security are a really important facet of any business. Every business owner wants their premises as safe and secure as possible without any unwanted visitors roaming around the premises. Facial Recognition Technology has been widely used for different functions and it’s about time people come to find out more about this wizardry.
Facial Biometrics is a technology capable of identifying someone by scanning and reading certain facial features. Facial Recognition Technology has come a long way and now have various applications in mobile platforms, robotics as well as matter of national security.
Different Techniques Used for Facial Recognition
Traditionally there are two different ways which are used for facial recognition.
1. In this system, 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 compressed probe image which contains all the required data to recognize the face of a certain person. The probe image is compared to the accessible face data to recognize the compulsory face out of the data pool.
In 3-dimensional face recognition, 3D sensors are used to record the facial features with more details such as the structure of the contour, spots, contour of the eye socket, chin, nose etc.. The additional benefit of 3D face recognition is that it is not determined by the light like the other methods.
In this technique, the facial features can be scanned in different lighting and a broad selection of viewing angles. This method drastically increases the precision in the process making it more reliable and usable in different conditions.
There are some other ways used for facial recognition like:
Skin Texture Analysis
Combination of different techniques (3D Face Recognition + Skin Texture Analysis)
Applications of Face Biometrics
There are lots of mobile apps 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 utilize this technique to improve their services.
Unlocking your phone with your face is nothing new but Apple has completely changed the game with their exact Face ID feature.
Various Police and National Security Agencies across the globe use facial recognition systems to track down criminals and identify suspects.
In large companies and government agencies, various biometric cameras and machines are utilized to automatically indicate the presence of employees or any certain individual.
