The inauguration ceremony of the 2016 Artificial Intelligence Hunan Forum and Zixing Artificial Intelligence Research Institute, many top experts from home and abroad gave us a report at the meeting. Researcher Sun Zhelan, a researcher at the State Key Laboratory of Pattern Recognition at the Institute of Automation, Chinese Academy of Sciences, and the director of Tianjin Zhongke Intelligent Identification Industry Technology Research Institute gave a detailed explanation on the topic of iris recognition.
This year is the 60th anniversary of artificial intelligence. Iris, face and fingerprint recognition are more practical artificial intelligence, and they are also several directions for successful development and utilization. Today's smartphones are basically unlocked with fingerprint recognition. Recently, the new mobile phones released by Samsung will have iris unlocking. Therefore, many people don't know much about iris recognition. I will give you a popular science.
What is an iris?The iris is an annular film located between the black pupil and the white sclera on the surface of the human eye. It exhibits rich visual characteristics such as spots, stripes, filaments, crowns, and crypts under infrared light.
Now the identity of the person is mainly recognized by face recognition and fingerprint recognition. In fact, the iris has great advantages.
1. Uniqueness: The formation of the iris is mainly determined by the random factors of the embryonic development environment. The random distribution of the iris texture determines the uniqueness of the iris pattern. The iris has a unique texture structure and the degree of freedom of detail on the iris. It is an order of a few hundred, so it can uniquely identify an individual.
2. Stability: The iris texture is stable after eight months of birth and remains unchanged for life.
3. Non-invasive: Non-contact collection, it may be obtained from a distance.
4. Security: Relative fingerprints and face features are not easy to steal. Most of the iris needs to be identified under infrared light. Because the iris is between the black pupil and the white pupil, most Chinese iris pigments can display detailed features below the near infrared, which can accurately identify a person's identity.
A brief history of iris recognition development
At the earliest, in 1936, the ophthalmologist discovered that each person's iris was different. He found that iris can be used for face recognition. In 1985, two other ophthalmologists applied for the first iris recognition patent in the United States. They believed that the iris could pass. Computer computers were used to implement them, but they didn't know how to implement them. Later, a researcher at the Harvard University in the United States, John Daugman, invented the first iris recognition algorithm. He expressed the iris recognition in the form of an algorithm and succeeded. Iris recognition is achieved.
Then in the 1990s, there were some products with iris recognition developed. Later, iris recognition proved to be a very safe and reliable identification technology, and it has been widely used in various fields, including customs, airports, and national ID cards. There are currently three countries that use the identity of the ID card as an iris. For example, everyone in India has assigned a number to collect irises. Now there are 1 billion collected iris recognition features, which have been very successful in India, Mexico, Indonesia, and now their national identity cards are also With the addition of iris features, the Institute of Automation of the Chinese Academy of Sciences began researching iris products in 1999. Later, we invented the iris application of mobile terminals. Perhaps the iris is such a development history.
At present, the application field of iris recognition is very extensive. Whether it is physical space or cyberspace, as long as it is a person identification, it can be used, such as an iris for security check, or an iris for safe counter-terrorism. Some terrorists can Make-up can even be easy to replace, or replace the fingerprint with a burn, but the anti-terrorism requires accurate identification, the iris is an important way. At present, our technology can also withdraw money from foreign bank ATMs with iris ID cards.
In addition, Samsung's newly released mobile phone uses iris recognition, Alipay also iris recognition, they also know that the future is an important direction of iris use, because fingerprints can be faked, it is possible to steal funds from Alipay through fake fingerprints. Fingerprints including cups of tea can be stolen because of security attacks. The management of public security judicial prisons, including coal miners, is used. In terms of access control, the iris also has broad application prospects.
Why do you like to use ferrite magnets? Because it does not rust, does not oxidize, does not corrode and is absolutely environmentally friendly.
Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
