Facial Biometric Search
[ad_1]
Security and privacy are a very important aspect of any business. Every business owner wants their premises 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. Facial Recognition 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.
Different Techniques Used for Facial Recognition
Traditionally there are two different ways which are used for facial recognition.
1. These algorithms identify the faces by first 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. The other way is to use a compressed probe image which contains all the necessary data to recognize the face of a certain person. The probe image is compared to the available face data to recognize the required face out of the data pool.
3D Recognition
In 3-dimensional face recognition, 3D sensors are used to record the facial features with more details like the structure of the shape, spots, contour of the eye socket, chin, nose etc. The additional advantage of 3D face recognition is that it is not dependent on the light like the other methods.
In this method, the facial features can be scanned in different lighting and a wide range 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
Thermal Cameras
Combination of different techniques (3D Face Recognition + Skin Texture Analysis)
Applications of Face Biometrics
Mobile Applications
There are many mobile apps which use face recognition for different purposes. Snapchat uses facial recognition to add a new filter which can change the way you look. Similarly, there are many such mobile apps which utilize this technique to improve their services.
Face ID
Unlocking your phone with your face is nothing new but Apple has completely changed the game with their precise Face ID feature.
Security Services
Various Police and National Security Agencies around the world use facial recognition systems to track down criminals and identify suspects.
Biometric Attendance
In big companies and government agencies, various biometric machines and cameras are used to automatically mark the presence of employees or any certain individual.
