facial biometric search

Security and privacy are a very important aspect of any business. All business owners want their premises to be as secure as possible with no unwanted visitors roaming the premises. All government security agencies use facial recognition software to track criminals and outlaws. Facial recognition technology has been widely used for different purposes and it is high time that people know more about this magic.

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 has diverse applications in mobile platforms, robotics, and even in homeland security.

Different techniques used for facial recognition

Traditionally, there are two different ways used for facial recognition.

1. These algorithms identify faces by first extracting facial features from an image of the subject’s face. In this method, the algorithm analyzes facial features like relative position, size, shape of nose, ears, cheeks, lips, etc.

2. The other way is to use a compressed probe image that contains all the data needed to recognize a certain person’s face. The probe image is compared with the available face data to recognize the required face from the data set.

3D recognition

In three-dimensional face recognition, 3D sensors are used to record facial features in more detail, such as shape structure, spots, eye socket outline, chin, nose, etc. The additional advantage of 3D facial recognition is that it is not dependent on light like the other methods.

In this method, facial features can be scanned under 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 facial recognition + Skin texture analysis)

facial biometrics applications

Mobile apps

There are many mobile applications that use facial recognition for different purposes. Snapchat uses facial recognition to add a new filter that can change your appearance. Similarly, there are many such mobile applications that use this technique to improve their services.

face identification

Unlocking your phone with your face is nothing new, but Apple has completely changed the game with its precise Face ID feature.

security services

Various police and national security agencies around the world use facial recognition systems to track criminals and identify suspects.

biometric assistance

In large companies and government agencies, various cameras and biometric machines are used to automatically mark the presence of employees or any given person.
