Biometric facial search
Security and privacy are a very important aspect of any business. All business owners want their facilities to be as safe and secure as possible without unwanted visitors roaming the premises. Facial recognition software is used by all government security agencies to locate criminals and outlaws. Facial recognition technology has been widely used for different purposes and it is about time that people learned more about this sorcery.
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 on mobile platforms, robotics, and even national security.
Different techniques used for facial recognition
Traditionally, there are two different ways that are 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 such as relative position, size, shape of the nose, ears, cheeks, lips, etc.
2. The other way is to use a compressed probe image that contains all the data necessary to recognize the face of a certain person. The image from the probe is compared to the available facial data to recognize the required face outside of the data set.
3D recognition
In three-dimensional facial recognition, 3D sensors are used to record facial features in more detail such as shape structure, spots, contour of the eye socket, chin, nose, etc. The added 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 with different lighting and a wide range of viewing angles. This method dramatically increases the precision in the process making it more reliable and usable in different conditions.
There are other forms of facial recognition such as:
Analysis of skin texture
Thermal Cameras
Combination of different techniques (3D facial recognition + skin texture analysis)
Applications of facial biometrics
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 mobile applications of this type that use 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 its precise Face ID feature.
Security services
Facial recognition systems are used by police and national security agencies around the world to track criminals and identify suspects.
Biometric assistance
In large companies and government agencies, various biometric cameras and machines are used to automatically mark the presence of employees or any particular individual.
