What was Adjustment with a Human Face?

Face recognition ^[1] technology refers to the use of computer technology for analysis and comparison to identify faces. Face recognition is a popular field of computer technology research, including technologies such as face tracking detection, automatic adjustment of image magnification, infrared detection at night, and automatic adjustment of exposure intensity.

Face recognition technology consists of three parts:

Face capture and tracking

Face capture refers to an image or

Area feature analysis algorithm widely used in face recognition technology, which integrates computer graphics

Generally speaking,

Facial recognition advantages

Compared to other biometric technologies:

Non-contact, the user does not need to be in direct contact with the device;

Non-mandatory, the recognized face image information can be proactively obtained;

Concurrency, which means that multiple faces can be sorted, judged, and identified in actual application scenarios.

Weaknesses in face recognition

Sensitive to the surrounding light environment, which may affect the accuracy of identification;

Obstacles such as hair and ornaments on the human face, and factors such as aging of the face require artificial intelligence compensation;

1. Business, residential security and management. Face recognition

Biometric technology is widely used in government, military, banks, social welfare, e-commerce, security and defense. For example, a depositor walks into a bank and makes a withdrawal without a bank card or a password. When he withdraws money at a cash machine, a camera scans the user's eyes and then quickly and accurately Has completed user identification and completed the business. This is a real shot from a business unit at United Bank of Texas, Texas. And the sales department is using the "iris recognition system" in modern biometric technology. In addition, after the "9.11" incident in the United States, anti-terrorist activities have become the consensus of governments of all countries, and it is important to strengthen the security of airports. Visage's face recognition technology has been used at two airports in the United States. It can pick out a face among the crowd and determine whether he is a wanted criminal.

With the further maturity of the technology and the improvement of social recognition, face recognition technology will be applied in more fields.

1. Enterprise and residential security and management. Such as face recognition access control attendance system, face recognition security door and so on.

2. Electronic passport and ID card. This may be the largest application in the future. The International Civil Aviation Organization (ICAO) has determined that from 2010, its 118 member states and regions must use machine-readable passports. Face recognition technology is the first recognition mode. Become an international standard. An e-passport program in China is stepping up planning and implementation.

3. Public security, justice and criminal investigation. Such as the use of face recognition systems and networks to search for fugitives nationwide.

4. Self-service. Such as bank ATMs, if the user's card and password are stolen, others will take cash. If face recognition is applied at the same time, this situation can be avoided.

5. Information security. Such as computer login, e-government and e-commerce. In e-commerce transactions are all completed online, and many approval processes in e-government have also been moved online. At present, the authorization of transactions or approvals is implemented by passwords. If the passwords are stolen, security cannot be guaranteed. But using biometrics, the digital identity and real identity of the parties on the Internet can be unified, thereby greatly increasing the reliability of e-commerce and e-government systems. ^[7]

In 2012, Wuxi adopted the Internet of Things face recognition technology to regulate the construction market. The construction site in Wuxi will start face recognition through the Internet of Things technology every day from June 1st. Through attendance management, ensure that project leaders are in place, and phenomena such as docking and subcontracting will be limited.

Face recognition systems have been built at the three stations of the Beijing-Shanghai high-speed railway, and facelifts can also be recognized. The railway department issued a plan to indicate that the identification systems of the three stations of Shanghai Hongqiao Station, Tianjin West Station, and Jinan West Station of the Beijing-Shanghai High-speed Railway Section have been completed to assist the public security department in arresting fugitive criminals. Using this system, even criminals after the crime will be able to be identified. ^[8]
