Face recognition is a biometric recognition technology that uses human inherent biometrics for identity verification. Human biometrics can be divided into two major categories: physiological characteristics and behavioral characteristics according to congenital innate and acquired characteristics. Physiological characteristics include common fingerprints, hand lines, face, palm prints, retina, iris, DNA, etc. These characteristics are all born by human beings. The behavioral feature is that the acquired face recognition is a typical way of using the biological characteristics of the human body to identify. Compared with other biometric identification methods, face recognition has the following advantages: formed, including signature, gait , tone of speech, etc. Compared with other authentication methods, such as password authentication and certificate authentication, biometrics have been widely used because of their advantages such as yiyi and non-forgery.
Face recognition is a typical way of using the biological characteristics of the human body to identify. Compared with other biometric methods, face recognition has the following advantages:
1. User is easy to accept, low invasiveness
Other recognition methods, such as iris recognition and fingerprint recognition, require a certain degree of cooperation from the user. Iris recognition needs to be very close to the recognition machine in order to extract iris information, which requires the user to place a finger on the fingerprint recognition machine. Face recognition requires a face image, and the photographing and recognition process does not need to be in close contact with the recognition machine. The user acceptance is high and the invasiveness is low.
2. Easy to expand
Other identification methods often require professional equipment, and the basic face recognition function only needs to use the camera and the ordinary computer, relying on the relevant identification software can be realized, no need to add other equipment, cost-effective, high coverage in the current surveillance camera and various industries It has been easily expanded and used when it has been widely used.
3. Intuitive
Face recognition is based on the facial features of people, which is in line with the human cognition of other people's identity recognition and intuitiveness.
