The face recognition technology that we have always admired is not perfect, and he will make mistakes. So what is the cause of its mistakes is still a big problem.
Face recognition has a wide range of applications, from access control, device login to airport, and public area monitoring. We are often similar to "Which star do you like the most?", "Predict your future look", "Look at your age difference?"... . Such some photo-screening based on face comparison.
At the moment, the details of face recognition technology are numerous and unclear, and the engineering skills are various, but the basic process has been fixed: when inputting a certain person's photo, using face detection technology to find the face position, on this basis Positioning key points, such as eyes, mouth, etc., after some geometric and optical corrections, extract facial features, and then achieve face recognition.
The London police recently tried a new facial recognition system, but they made an embarrassing mistake. At the Notting Hill Carnival, when the police used the technology to search for suspects, about 35 wrong identity matches occurred and one of them was "incorrectly" arrested.
The failure of this technology means that visual surveillance relies mainly on monitors sitting in snow-white rooms to watch hours of camera footage, which is simply not enough to maintain people in a city. But recent research has shown that video analytics software can be greatly improved thanks to a completely different area of ​​software advancement: DNA sequence analysis. By matching the evolution of DNA to video, these software tools and techniques can be turned into automatic visual monitoring.
The camera-based visual surveillance system is theoretically able to ensure a safer social environment. However, even after decades of development, they still cannot fully handle the real-life situation. For example, during the 2011 London riots, facial recognition software identified only one of the 4,962 suspects and completed the arrest.
Through these different application methods, face recognition technology not only brings convenience to people's lives, but also adds to the fun of life. In the Internet age, face recognition technology is applied to many occasions. How to ensure data security and rational use of technology is a topic that cannot be ignored. Only with safe and reasonable use can we play the role of face recognition technology and bring benefits to people's lives.
