Top of the Great Era

Chapter 1336 Face Recognition Is Complicated

The choice of technology development direction is actually a game of rock-paper-scissors between scientists and the times.Capital institutions don't like to hold stocks of R&D companies for a long time, because this thing is too risky, and the element of luck is too great.

For example, when the top chip companies in the world enter the mobile Internet era, most of them will die in the rapid iteration of 3g, 4g, and 5g.

Zhou Buqi has an advantage.

For him, in this rock-paper-scissors battle with the times, the times come out first, and he comes out last.

Therefore, he can conclude that the scientific research idea of ​​this multimedia laboratory is correct and has great prospects, so he can 100% confirm that this laboratory is the famous SenseTime.

However, this multimedia laboratory still lacks a leading figure. The director of the laboratory, Professor Tang, is a pure scientist. He leads some professors and students, and his understanding of marketization is far from enough.

Zhou Buqi is different. He will soon be able to combine their image processing technology with the market and play a very important role.

There is still a long way to go for this technology to transform uncertain blurred pictures into definite clear pictures, and it may take 10, 20, or 30 years of struggle.

However, they can basically clear up blurred pictures within the certain range of human eyes.

This is enough to have a great positive effect on the social level.

Zhou Buqi was very happy, and felt that coming to Hong Kong this time really made a lot of money.Shen Xiangyang must be notified immediately to let him come over to start an in-depth and all-round cooperation with this multimedia laboratory.

After leaving, Superman was still in a daze, as if he didn't understand anything.

Zhou Buqi laughed, "Thank you for helping me fund this team in the past few years, thank you!"

"what?"

Little Superman was stunned. This is a scientific research team funded by me. The establishment of this multimedia laboratory was funded and helped by me.

Hearing this tone, has it become yours?

Even if it’s not mine, it’s also from Hong Kong Island Chinese University. Do you want Mao’s relationship?
Zhou Buqi said: "Little Superman, it's not that I want to cut him off halfway, it's because the scientific research topics in this laboratory are too cutting-edge, not to mention you, there are not many companies in the world who can catch it. In the Eastern Hemisphere, only Zi MSI is qualified to cooperate. Don’t worry too much.”

"What's bothering me?" Little Superman was annoyed and funny, "I funded these scientific research teams for the purpose of public welfare, and I never intended to obtain anything."

Zhou Buqi gave a thumbs up, "Yes! This pattern is correct!"

Little Superman invited: "Would you like to visit my house when you are free?"

"what?"

"My father wants to talk to you."

"Okay, I must pay a visit and go to study."

"At that time, you can explain what happened today."

Zhou Buqi raised his eyebrows, "What did you say?"

Xiao Chaoren said: "Just say that this is a scientific research team that I have funded for many years and I am very optimistic about. Because of its own lack of strength, I will transfer it to Ziweixing to continue to follow up."

Zhou Buqi lowered his voice, "Is your family's investment in the high-tech industry yours or your elder brother's?"

Little Superman smiled half-smile, "Mr. Zhou, your question is very impolite."

Zhou Buqi hooked up with him boldly, "We are friends, and I'm from the Northeast, so I don't care about these details... Well, do you know that from the Northeast?"

Little Superman said: "I know, drinking is fiercer than white devils, and fighting is fiercer than triads."

"I'm talking about character, okay?" Zhou Buqi snorted, vowing, "We Northeast people are all hospitable and generous. If you need my help, just ask."

"Ok."

Little Superman smiled and didn't mention anything about the family affairs.

Zhou Buqi said: "Businesses such as wharves, real estate, retail, transportation, and tap water are actually similar, and they are all traditional industries. But the idea of ​​high-tech industries is different. I think your family's high-tech investment and industries, It is right to give it to you."

Superman was very happy.

A group of people were walking on the campus of the Chinese University of Hong Kong, and Little Superman deliberately got closer to him, and whispered: "Miss Wen Yongshan in the morning, don't you like it?"

Zhou Buqi coughed lightly, "Not very familiar."

Little Superman said: "I've made all the arrangements, it's no problem for you to take it out and open a room."

"I'm not that kind of person."

"is it?"

"Yeah." Zhou Buqi coughed again and said in a low voice: "She may be very popular here on Hong Kong Island, but I have never heard of her. In mainland China, what is our understanding of Hong Kong Island's entertainment industry?" , or old Hong Kong films and the Four Heavenly Kings.”

"Many Gan people will die without seeing you die!"

Little Superman said something in Cantonese, a curse word.

Of course Zhou Buqi knew that he was not scolding himself, so he was very surprised, and dragged out a sentence in English, "What are you talking about?"

Little Superman said angrily: "I scolded Chen Guanxi."

Zhou Buqi laughed and said, "What happened to him?"

Little Superman said: "The photo gate he created has ruined the most popular female stars in Hong Kong Island. I will arrange it for you. You must not be interested."

Zhou Buqi felt that what he said was too reasonable, and said righteously, "I'm not interested in this kind of thing, so you don't have to bother to arrange it."

Together, we investigated 4 laboratories at the University of Hong Kong, the University of Science and Technology and the University of Science and Technology, and all of them are really good.

Among them, the "Data Center Higher Temperature" project conducted by an energy laboratory of the University of Hong Kong is particularly optimistic, and it is in line with Ziweixing's needs.

At present, the PUE of mainstream data centers in the world is about 2, that is, computing equipment such as servers consumes 1 kWh of power, and corresponding auxiliary equipment such as air conditioners also consumes 1 kWh of power.The effective power consumption is 1, and the real power consumption is 2.

However, in some data centers with excellent energy control, the power consumption can be as low as 1.7.The power consumption PUE of Ziweixing's cloud data center in the capital is about 1.8.

Their research topic is how to make computers and servers run safely and stably at relatively high temperatures.If it is done, there is no need to turn on the air conditioner so much, and it will save electricity.

This topic is very important to the business of metacomputing.

No wonder Superman feels so frustrated. Hong Kong Island really has no shortage of talents. Among the 15 best universities in Asia, Hong Kong schools can rank in 5, and the level is really good.

It seems that Ziweixing's Hong Kong branch should take on more important tasks. It will open a research institute and connect with Hong Kong schools.Retain talents, so as not to go to Britain, the United States and other countries.

In the evening, Zhou Buqi refused Little Superman's entertainment, and accompanied Pei Yao and Sun Guanran for dinner, and asked the Pengcheng branch to strengthen ties with the Hong Kong school.

Especially the multimedia laboratory is really great, and it can be directly commercialized.

"Direct commercialization?" Pei Yao was slightly taken aback, not quite understanding, "Isn't it too early?"

Zhou Buqi said: "If possible, I think it can be introduced to the market next year. For this kind of thing, the sooner the better, it will benefit the country and the people."

"Uh……"

Pei Yao is used to the boss's big mouth.

Zhou Buqi smiled and asked: "By the way, in the multimedia laboratory, Little Superman mentioned a case, saying that there are often such plots in Hollywood movies. The satellite captured a person in the city, but the face was too blurred. Then, send the blurred face to the technology center for clear processing, and then compare it with the personal information in the database to find out who the person is."

Sun Wanran said softly, "Didn't Professor Tang say that this is impossible."

"That's right, it's impossible." Zhou Buqi also knows that movies mislead the public too much, "I don't think it will be possible to transform an uncertain image into a definite image without ten or twenty years of technological accumulation. Then the question Here, what if it is a clear image? There are also some film and television dramas that have such plots. There is a photo. I don’t know who is the person in the photo. The police scan the photo into the computer, and then the computer can identify the person. Combined with the profile picture on the certificate, this person can be found.”

Sun Wanran tentatively said, "This should be true, right?"

"fake!"

Zhou Buqi is very decisive.

Sun Guanran looked suspicious, "Is this a difficult technique? It should be possible, right? If not, how will the public security department handle the case and investigate?"

Zhou Buqi said: "I don't know about the United States, and it is definitely not possible in China. Isn't Meng Houkun's uncle some kind of bureau chief? I talked to him. They used the most stupid method, asking the police to use their eyes to check with the database. ID card headshots to compare photos one by one."

"That's such a hassle!"

"This is the importance of artificial intelligence. Forget it, you two don't understand technology, let me teach you a lesson, talk about the history of image processing of artificial intelligence."

Without the presence of experts, Zhou Buqi is enough to act like a boss in front of these laymen.

Sun Guanran pouted, "Do you understand?"

Zhou Buqi snorted coldly: "Why don't you understand? Listen! In the 80s, computers were able to recognize some simple objects. For example, cars, trees, and tigers, computers can recognize them through the method of prior knowledge base. That is First manually transfer these things to the database, which is almost the same as in the database, and then it is recognized. But the accuracy is very poor, and apples and cherries may not be able to distinguish.”

"Oh."

Sun Wanran despised him, thinking that he could really pretend.

Zhou Buqi went on to say: "In the 90s, new algorithms appeared, which could describe local features. This is the origin of contemporary artificial intelligence image recognition technology, and our CTO Shen Xiangyang is the founder of related theories. However, , this process also requires manual entry or manual setting of recording rules for some local features, and then the computer can distinguish."

"Can it be automatically entered now?"

"That's right. After entering the 21st century, machine learning methods have been widely used, and computer vision has developed rapidly. Computers can automatically summarize the characteristics of items from massive data, and then identify and judge them."

"Oh."

Sun Guanran and Pei Yao looked at each other, both a little confused.

Zhou Buqi sighed, "Forget it, you are all technical novices, and you don't understand even if I tell you. Let me tell you, Shen Xiangyang is leading a team to do a project, which is image recognition."

"Yellow map recognition program?"

"Yes, loess recognition is relatively simple, and more importantly, face recognition. This is not a blurred picture, but a very clear photo. For example, take a picture of your face at different angles, which is a 2D photo. Then use the 2D photo 3D modeling. Then determine whether the face in these photos is a person."

Sun Guanran was a little surprised, "It's so complicated!"

Zhou Buqi said: "I've put it simply. Human faces are so complicated. It's like giving the computer recognition of your two faces. The computer can easily judge that this is a woman. Let the computer judge that you two are It is not the same person, which requires a very detailed judgment."

Pei Yao said: "So as you said just now, it is not possible to scan the photos of people who have acted in many film and television dramas into the computer, and then the computer can automatically connect with the database to find out who this person is."

Zhou Buqi nodded, "Yes, the artificial intelligence level in the past could not distinguish too much detail, especially human faces, which may have different changes at different ages, and 3D modeling is needed to reduce errors. Remember, I'm talking about a sharp photo versus a sharp photo."

"Can it be done now?"

"Isn't yellow image recognition doing very well, and face recognition is a step forward. Now it can basically be done, but the accuracy rate is too poor, it seems to be only 16.7%."

"So low?"

Sun Guanran slapped his forehead, feeling that the distance between film and television dramas and reality is so far away.

With the current technology, upload personal photos to the computer of the public security system, and then compare them with the ID card photos in the citizen database... This technology does not yet exist, and the only way to rely on the police is to keep going one by one in the database Check it out and compare it with human eyes.

The efficiency of this case handling is too poor, and it also delays things!

Fortunately, according to what he said, it seems that Ziweixing can help solve this problem.

Damn!

If it does, it's really meaningful.

Unfortunately, the accuracy rate is too low.

"Low?" Zhou Buqi snorted, "This is artificial intelligence. No matter how low the accuracy rate is, it is better than human eyes to judge one by one, right? The accuracy rate of 16.7% is equivalent to improving the screening efficiency of the police by more than 80%. .Combined with the human eye, it can basically connect the face in any photo on the Internet with the ID card information in a few minutes."

Sun Guanran nodded again and again, and said happily: "Yes! It's really meaningful! It's a good thing!"

Zhou Buqi laughed, somewhat proud of himself. At his level, he feels that doing this kind of thing is more enjoyable than making money, "However, what Shen Xiangyang did was to compare clear pictures with clear pictures. But many current surveillance resolutions It is very low, and what you get is a blurred picture, which can be combined with Professor Tang's research."

Sun Guanran blurted out, "First convert the blurred picture into a clear picture, and then compare the pictures for recognition."

"Yes." Zhou Buqi nodded, "But this blurry picture can only be a blurry picture within the range of the naked eye. It can only be relatively blurry, not too blurry."

"But this direction is correct." Pei Yao is also very happy, and feels very fulfilled working in Ziweixing. "At this stage, it is the clear transformation of deterministic pictures. With the iteration and upgrading of technology, we can turn to uncertain The picture developed. This project can be launched first, and then help the police to update equipment and upgrade the system little by little until it reaches the performance in Hollywood movies.”

Zhou Buqi smiled and said, "Yes, that's right!"

Pei Yao said: "There are all kinds of printed pictures posted in the streets and alleys, saying that they are missing children or women, but how to check them? It is also difficult for the police to check. With our technology, there will be computer screened pictures. Possibly. As long as the photos of the missing children or women are uploaded on the Internet, or the corresponding images are intercepted from the surrounding cameras, the comparison, docking, and confirmation can be completed, and then the person can be found through the source of the photos.”

Zhou Buqi sighed, "It's not that simple."
