Why can Megvii become one of the Four Tigers of Computer Vision ?

Vision enables humans to perceive and understand the world around them, while computer vision enables machines to understand and understand the world, that is, to perceive and understand images through electronic means, so as to achieve or even surpass the effect of human visual intelligence.

Specifically, it is mainly to study how to make the machine "see", usually using cameras and computers instead of the human eye to identify, track and measure the target and other machine vision, and further do graphic processing. With computer vision, the computer will process images that are more suitable for the human eye to observe or transmitted to the instrument for inspection. The main task of computer vision is to obtain the three-dimensional information of the corresponding scene by processing the collected ** or **.

First, it is a very important problem that AI needs to solve. Second, it's a strong driver of AI right now. Because it has many applications, many technologies are reapplied to the field of AI after the birth of computer vision.

Third, computer vision has a large application base for quantum AI.

Since 2014, "artificial intelligence" has become the direction of capital attention, and so far there are more than 500 investment institutions with a cumulative investment of more than 60 billion yuan. Especially after the second half of 2017, the single financing amount of some companies such as SenseTime Technology and Megvii Technology was as high as more than 1 billion yuan. Recently, SenseTime and YITU have announced that they have received C+ round of financing, which shows that the attention of capital to artificial intelligence is still hot.

It is not difficult to see from the heat of capital chasing that computer vision, as a subdivision of artificial intelligence, has achieved remarkable commercial results and great potential in the application field. According to IDC's recently released "IDC 2018 China Computer Vision Application Market Research", as of the end of December 2017, China's scale in this field reached 100 million yuan, an increase from 2016.

Because they have a strong research on the direction of computer development.

Because they are technologically advanced and have strength.

Because Megvii Technology not only has face recognition technology, but also has mastered artificial intelligence technology.

Because this company has a very cutting-edge technological vision.

There are a large number of researchers behind Megvii's technological strength, so it is not surprising that it has made visual achievements.

Probably because their visual experience is handled too well.

Because his R&D ability is awesome.

I've never heard of this company, so let's develop it.

Behind the strength of Megvii's technology is a large number of researchers.

1. Computer, commonly known as computer, is a modern electronic computer used for high-speed calculation, which can perform numerical calculations and logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed.

2. A computer composed of a hardware system and a software system without any software installed is called bare metal. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

3. John von Neumann, the inventor of the computer. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

4. The application of computers is becoming more and more common in China, after the reform and opening up, the number of computer users in China has been rising, and the level of application has been continuously improved, especially in the fields of Internet, communications, and many other fields. From 1996 to 2009, the number of computer users increased from 6.3 million to 67.1 million, and the number of networked computers increased from 10,000 to 59.4 million. The number of Internet users has reached 100 million, and there are 100 million mobile Internet users on the wireless Internet, including 100 million mobile Internet users, ranking first in the world.

High computing speedComputing speed is an important performance indicator of a computer. The speed of a computer is usually measured in terms of the number of times a fixed-point addition is performed per second or the average number of commands executed per second. The speed of computing is a prominent feature of computers.

2.High Accuracy of CalculationsIn scientific research and engineering design, there are high requirements for the accuracy of calculation results. The general calculation tool can only reach a few significant digits (such as the four-digit mathematical table, eight-digit mathematical table, etc., which were commonly used in the past), and the computer can reach more than a dozen or dozens of significant digits for the accuracy of the data, and even reach any accuracy according to the need.

3.Large storage capacityThe memory of a computer can store a large amount of data, which gives the computer a "memory" function. At present, the storage capacity of computers is getting larger and larger, and the capacity has reached the order of kilogiga.

Computers have a "memory" function, which is an important difference from traditional computing tools.

4.In addition to basic arithmetic operations, the combinator with the function of logical judgment computer also has the function of logical operations such as comparison and judgment. This ability is a prerequisite for computers to deal with logical reasoning problems.

5.The degree of automation is high, and the versatility is strong, because the working mode of the computer is to store the program and data in the machine first, and the operation according to the program regulations when working, step by step is automatically completed, and there is generally no need for manual intervention, so the degree of automation is high. This feature is not found in general calculation tools.

The characteristics of the generality of computers are manifested in the fact that they can solve almost all types of problems in the natural sciences and social sciences, and can be widely used in various fields.

The main features of the computer are:

1. Fast operation speed: the internal circuit of the computer is composed of various arithmetic operations at high speed and accurately. Today's computer systems have a computing speed of trillions per second, and microcomputers can reach more than 100 million times per second, enabling a large number of complex scientific computing problems to be solved.

2. High calculation accuracy: the general computer can have more than a dozen or even dozens of (binary) significant digits, and the calculation accuracy can be from a few thousandths to a few millionths, which is beyond the reach of any calculation tool.

3. Strong logical operation ability: the computer can not only perform accurate calculations, but also have logical operation functions, and can compare and judge information.

4. Large storage capacity: The memory inside the computer has memory characteristics and can store a large amount of information, which not only includes all kinds of data information, but also includes programs that process these data.

5. High degree of automation: because the computer has the ability to store memory and logical judgment, people can incorporate the pre-programmed program group into the computer memory, and under the program control, the computer can work continuously and automatically without human intervention.

6. Cost-effective: almost every household will have a computer, which is becoming more and more common and popular, and the computer will become one of the indispensable electrical appliances in every household in the 21st century. Computers are developing rapidly, and there are desktops and laptops.

Computers have the following characteristics:

Fast computing power.

The work of an electronic computer is based on the principle of an electronic pulse circuit, which consists of electronic circuits that constitute its various functional components, in which the propagation of electric fields plays a major role. We know that electromagnetic fields travel very fast, and today's high-performance computers can perform tens of billions of additions per second. If a person can do an operation in one second, then the average computer has to do more than 100 years of work in one hour.

In many cases, the speed of the operation plays a decisive role. For example, computer-controlled navigation requires "computing speed faster than an airplane flying"; Meteorological forecasting requires the analysis of a large amount of data, such as 10 days and a half months for manual calculation, which loses the significance of forecasting. With a computer, you can calculate a weather forecast for several days in an area in a few minutes.

Sufficiently high calculation accuracy.

The calculation accuracy of the electronic computer is not limited in theory, and the general computer can reach 15 significant digits, and any accuracy requirements can be achieved through certain technical means. There is a famous mathematician in history who once calculated pi and spent 15 years to calculate the 707th place. Now if you leave this to a computer, you can count 100,000 bits in a few hours.

Super memory.

There are many storage units in a computer that are used to memorize information. Internal memory is an important differentiator between computers and other computing tools. Due to the ability to memorize information internally, it is not necessary to obtain data from the outside every time in the process of calculation, but only need to input the data into the internal storage unit in advance, and the data can be obtained directly from the storage unit during the calculation, thus greatly improving the calculation speed.

The capacity of a computer's memory can be made very large, and it has a particularly strong memory.

Complex logical judgment ability.

People have the ability to think. Thinking ability is essentially a logical judgment ability, which can also be said to be the ability to analyze cause and effect. With the help of logical operations, the computer can make logical judgments, analyze whether the proposition is true, and make corresponding countermeasures according to whether the proposition is true or not.

For example, there is a "four-color problem" in mathematics, which says that no matter how complex a map, it is enough to make adjacent areas different in color, and at most four colors are enough. For more than 100 years, many mathematicians have tried to prove it or disprove it, but they have been inconclusive, and it has become a well-known problem in mathematics. In 1976, two American mathematicians finally used computers to perform very complex logical reasoning to verify this famous conjecture.

The ability to work automatically as programmed.

The general machine is controlled by a person, and the person gives the machine a command, and the machine is finished and becomes an operation. The operation of the computer is also controlled by people, but because the computer has the ability of internal storage, the instructions can be entered into the computer in advance and stored, and after the computer starts to work, the instructions are taken from the storage unit in turn, and the operation of the computer is controlled, so that people can not interfere with the work of the computer, and the operation is automated. This way of working is called program control.

1. Fast operation speed and high precision. Modern computers can run millions of instructions per second, and the speed of data processing is unmatched by any other tool.

2. Have the ability to store and remember. A computer's memory is similar to a human brain and can "remember" (store) large amounts of data and computer programs.

3. Have the ability to make logical judgments. Having the ability to make reliable logical judgments is an important reason why computers can realize the automation of information processing. It can make logical judgments, so that the computer can not only calculate the numerical data, but also process the non-numerical data, so that the computer can be widely used in the field of non-numerical data processing, such as information retrieval, graphic recognition and various applications.

4. High degree of automation. When using a computer to solve a problem, after people start the computer input the programmed program, the computer can execute it automatically, and generally does not require human direct intervention in the calculation, processing and control process.

The most advantageous feature of computers is that they are artificial intelligence robots, which help people do their work, and other advantages are negligible. For example, in terms of entertainment, games and movies**, the visual and auditory characteristics of virtual are all addicted to the body.

The second computer is characterized by convenience, power, and practicality.

Strong memory ability, high calculation accuracy and accurate logical judgment, high-speed processing ability, can automatically complete various operations.

Nowadays, computers are used in every industry, so if you learn it, you must learn it well, and computers are easy and fast to use. It can also do a lot of things, and the main computer is now an indispensable tool for human beings.

Learning computers is boring, but it's also very practical. If you study computer science, you must learn well and be proficient, otherwise it will be difficult to get employed.

Computer Maintenance:

The main maintenance of the host, mainly the working environment, do not use it for a long time in too hot weather, and the air-conditioned room is the best.

Turn off the phone every day, don't be too troublesome, and turn it off when you don't use it every day. However, don't turn on and off frequently, you will use it again in an hour or two, and you don't need to turn it off in the middle.

How about the working environment, if the dust is relatively large, you can open the box regularly to clean up the dust, do not be too detailed, just blow the dust off, do not wipe the motherboard with a wet towel, and use it with caution when the voltage is unstable.
