Privacy and security are a really important aspect of any business. Every business owner needs their premises as safe and secure as possible with no unwanted visitors roaming around the premises. Every government safety 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 find out more about this wizardry.
Facial Biometrics is a technology capable of identifying someone by reading and scanning certain facial features. Facial Recognition Technology has come a long way and today have various applications in mobile platforms, robotics and even matter of national security.
Different Techniques Employed for Facial Recognition
Traditionally there are two unique ways that 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. Another way is to use a compressed probe image which contains all the necessary information to recognize the face of a specific individual. The probe image is compared to the available face data to recognize the required face from the data pool.
In 3-dimensional facial recognition, 3D detectors are utilized to record the facial features with more details like the structure of the shape, spots, shape of the eye socket, chin, nose etc.. The additional benefit of 3D face recognition is that it’s not determined by 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 precision in the process making it more reliable and usable in various conditions.
There are some other ways used for facial recognition such as:
Skin Texture Analysis
Combination of different techniques (3D Face Recognition + Skin Texture Analysis)
There are lots of 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 lots of such mobile apps 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 precise Face ID feature.
Various Police and National Security Agencies around the world use facial recognition systems to track down offenders and identify suspects.
In big companies and government agencies, various biometric machines and cameras are utilized to automatically mark the presence of employees or any certain individual.
