Do you know what are facial recognition advantages and disadvantages?
What is facial recognition technology?
Facial recognition technology is non-contact recognition, face features within a certain range can be recognized at the same time, fast, compared to fingerprint collection and voice collection, recognition speed is faster, enhanced security, has a high accuracy rate, and can make the process automated, intuitive naturalness, non-compulsory, not easy to counterfeit, low cost, easy to promote the use of advantages and so on.
As one of the biometric technologies, the accuracy of face recognition has exceeded 99%, which is much higher than the familiar fingerprint recognition and voice recognition.
The principle of facial recognition technology is a biometric technology that analyzes and calculates the features of the human face and then carries out identity recognition. It uses a camera to collect photos or videos of the human faces and detects and tracks their face in them so as to realize the recognition of the human faces.
Facial recognition advantages and disadvantages' advantages
Facial recognition advantages and disadvantages advantages 1. Facial recognition is non-contact recognition, he does not need direct contact with the device to obtain face image features.
Facial recognition advantages and disadvantages advantages 2. A kind of multiple people carry out a kind of recognition at the same time, and facial features within a certain range can be recognized at the same time.
Facial recognition advantages and disadvantages advantages 3. Fast speed, compared to fingerprint acquisition and voice acquisition, recognition speed is faster.
Facial recognition advantages and disadvantages advantages 4. With enhanced security, with the help of a 3D biometric system and infrared camera, facial recognition can be performed more efficiently. Company premises can be protected by monitoring employees and visitors.
In addition, intruders can be identified immediately. Thus, facial recognition can significantly improve workplace security. For example, the concert of singer Jacky Cheung has caught several people at large through facial recognition technology.
Facial recognition advantages and disadvantages advantages 5. Facial recognition technology has a high accuracy rate. Facial recognition is calculated by calculating the features of a person’s face and then comparing the face with the samples in the sample library to get an accurate recognition result.
With the help of artificial intelligence and machine learning, face recognition has achieved a higher success rate. As a result, the chances of spoofing the system or hacking are greatly reduced. Security systems can now accurately identify people who have illegally entered private property and notify the appropriate authorities.
Facial recognition advantages and disadvantages advantages 6. Instead of hiring security officers to identify people, facial recognition technology can automate the process.
Manual identification can be a tedious process and presents the opportunity for error. However, facial recognition works 24/7, automatically identifies faces, and provides more reliable results.
Facial recognition advantages and disadvantages advantages 7. Intuitive naturalness.
Intuitive naturalness refers to distinguishing and confirming identity by observing and comparing faces, which are intuitive sources of information that the naked eye can judge. Convenient for manual confirmation, in line with the laws of human cognition.
Facial recognition advantages and disadvantages advantages 8. Non-compulsory and not easy to counterfeit.
The recognized face image information can be actively acquired without being detected by the measured individual. Facial recognition is the use of visible light to acquire face image information.
Unique to facial recognition technology, facial recognition technology requires the recognition object to be physically present at the recognition site. Unlike fingerprint recognition or iris recognition which requires the use of electronic pressure sensors to collect fingerprints, these special collection methods are easily perceived and thus carry a deceptive nature that can be disguised.
Facial recognition advantages and disadvantages advantages 9. Low cost, easy to promote use.
Because the recognition technology uses regular general equipment, the price is in the general user can accept the range, compared with other biometric technology, the face recognition product has a very high performance-price ratio.
A new generation of technology-driven industrial revolution represented by facial recognition has already emerged. In the future, facial recognition systems will be used in various fields and become more and more mature. In the multimedia exhibition and display industry, face recognition systems can be applied to exhibition hall door locks, etc.
What are the disadvantages of facial recognition?
The disadvantages of facial recognition are that there will be errors, which will affect the result of human judgment; the reliability and stability of information are weak; the amount of information contained in the face is relatively small, and the complexity of its changes is not enough, and the recognition is not very high; the inner changes of the person himself and the changes of the external environment will affect the stability of the information of the face when it is collected.
From the perspective of the technology level, the human face is the only biometric information that can be collected without the active cooperation of the user. Other biometric features, such as fingerprints, palm prints, iris, veins, and retinas, require the active cooperation of the user, i.e., if the user refuses to collect, high-quality feature information cannot be obtained.
From the social-psychological point of view, identification by face is in line with the human visual identification experience and is easily accepted by users.
For example, people worry about privacy leakage when collecting fingerprints and irises, but they do not feel violated when they are filmed by hundreds of surveillance cameras on the street every day, because the face is naturally exposed and is considered a natural feature for identity recognition. So what are the disadvantages of facial recognition technology?
The Facial recognition advantages and disadvantages' disadvantages
- Facial recognition technology can also have errors that affect the results of human judgment.
- A disadvantage of face recognition is that the reliability and stability of the information are weak.
- The amount of information contained in the face is relatively small compared to biometric features such as fingerprints and iris, and the complexity of its changes is not enough. For example, if two people’s fingerprints or irises are basically the same, it takes several dozen or even hundreds of bits to achieve a complete overlap. But in the case of a human face, a dozen or so bits to achieve overlap is sufficient. Many faces with similarities can be found all over the world. Therefore, the face is not very recognizable, it is not that unique.
- In addition, the internal changes of the person himself and the changes in the external environment will affect the stability of the information on the face when it is collected. Compared with the previous face recognition technology, the current face recognition technology has improved, but the specific application is still not perfect, and the accuracy rate of face recognition technology can reach 99% by conservative estimation.
