What is face detection or recognition?
Face detection or recognition system is a technique through which human face is identified. The Identification is done either from image or video. The recognition system uses multiple methods of capturing facial features and comparing with the already captured data. Biometric Artificial Intelligence application identify human and analyze facial textures of a person. Face recognition system is a form of security feature just like a fingerprint or Iris recognition system.
How does facial recognition system work?
The face recognition process is performed in two stages. In first stage, the facial features of a person having unique identity are recorded. Where as in second stage, captured features are classified and matched with available database.
Facial recognition algorithm is used to capture features such as size, position, shape and colour of parts of person which includes eyes, nose, cheekbones and jaw. This algorithm uses two techniques. The first one is called geometric technique in which distinguish features are recorded. The second technique is called photometric technique in which every image is converted into values for comparison. The measurement system uses 3 dimensional feature which captures facial textures from different angles with the help of sensors.
Facial recognition system software uses multiple technique. It uses Skin texture analysis to cover the skin part of human. Thermal imaging is used to capture energy level in low light conditions.
What is the purpose of facial recognition system
Facial recognition is used in ID verification. Many mobile phone manufacturers use face ID as facial recognition measurement system. Different countries are also using this system to implement security through law enforcement agencies.
The benefits of facial recognition system is that unlike fingerprint and Iris recognition system, face of a person can be easily detected even in the crowded place without disclosing it. The accuracy of other security systems are ahead of facial recognition system, however its application and acceptability has increased over the years due to quick response and practicality. In addition. Non contact nature of application has increased its popularity and demand over the time.
