The thrilling day passed so easily. Back in the dormitory, Zhang Qiu had the opportunity to study the updated system.

As soon as he opened the interface, Zhang Qiu felt that the interface was completely new and more technological.

The first thing that catches your eye is the announcement of the successful upgrade of the system: "Congratulations, you have successfully upgraded to a level 1 system, the number of passive beauty radar uses per day has been increased to 2, the effective distance has been increased to 30 meters, and the number of active beauty radar uses has been increased to 1." The upgrade score is passed, and 1 new function is added to the upgrade special reward: task reminder (abbreviated). ”

"The punishment system is on: if the number of new tasks reaches 16 after being upgraded to level 1, and the completion degree is less than 60 points, and it is judged to be a failure, the level will be cleared. After three failures, the user will be disqualified. ”

"The number of tasks required to reach level 2 is 1/16."

I'll go, there is a punishment system, but fortunately the punishment is not heavy! But those tasks that appear, I don't know when they will disappear, just like the two that have not been completed, and they will disappear as soon as I hesitate. It seems that I will be able to complete the task as quickly as possible in the future, even if it is a lewd task such as peeking and sneaking.

Otherwise, it is very likely that the qiē that Zhang Qiu has will be lost.

I took a look at the interface of the tasks that have appeared, and it is sorted according to the level. At level 0, there are 8 tasks, two of which have not been completed, "What's Under a Girl's Skirt" about Su Yun and "A New Understanding - A Hug Between Men and Women" about Ning Lan.

At level 1, there was just one that appeared, and it was already completed, and it was about He Qing's "serving the people".

The description of this newly completed task is much more detailed than the eight tasks at level 0, probably due to the new feature "Task Hint (Abridged)".

Looking at this new version of the mission description, Zhang Qiu deduced a lot of information. First of all, the first main story task is "acquaintance", and to summarize the main story tasks that appeared earlier, it seems that they are all acquaintances.

The first main mission that appeared after getting the system was about Su Yun's acquaintance, because he completed it almost effortlessly, and the reward was only a few hundred yuan, so it was speculated that the difficulty of the task should be "easy".

The simple main quest only rewarded RMB, but the main quest that was just completed today is also an acquaintance task of a city-level beauty, but it rewards a technological item. It can be seen that the more difficult the task, the better the reward.

Zhang Qiu couldn't help but think of the task of peeking at the bottom of Su Yun's skirt, and he didn't know what level that task would be? Visual inspection is a higher level of difficulty than slightly harder, and if you were brave enough to complete this task, what would you reward?

Thinking of this, Zhang Qiu regretted it. People, it's not okay to be too reserved, you have to be a hooligan when it's time to be a hooligan, maybe the opportunity to change your fate is here.

Thinking of Su Yun, Zhang Qiu suddenly thought of asking her to transfer money.

Although Zhang Qiu has an Alipay account, he has not bound his mobile phone, and has only done real-name authentication. Now there is no way to know that Su Yun has transferred the account through the guò text message, so I can only log in to the account through the guò computer and check it.

Open Alipay immediately and log in to your account. I saw that there were already 20,000 yuan more in it, and there was a transfer message. "Xiaoqiu, don't shirk, this is what you deserve. Mr. Mu reimbursed me 12,000, and I took 2,000, so I will still invite you to dinner. ”

It seems that Su Yun's sister is not bad, she is not so greedy for money. In this case, Zhang Qiu is not hypocritical, I have transferred the extra 10,000 yuan back.

After binding the mobile phone, Zhang Qiu transferred the money to the current hot Yue Bao.

After doing this, Zhang Qiu looked at the "character recognition engine (primary technology)" that had not yet been extracted in the reward list. I don't know what this thing is, but is it a software? Or is it a terminal?

"Extraction" With a strong curiosity, Zhang Qiu withdrew this reward.

"The reward is software, please select the carrying object. If you find a laptop and a mobile phone that can carry objects, please select. ”

"Laptop!"

It turned out to be a pure software, not a terminal that integrates software and hardware, Zhang Qiu was a little disappointed. But since it's just a piece of software, it means it's more versatile.

In the next second, there was an extra text folder on the computer desktop - "Character Recognition Engine".

After opening the text folder, there are two articles, one is the compiled executable text and the other is the source code that has not yet been compiled.

The name of the executable text is called "Elementary Person Recognition Engine: Action Recognition", and the overall size is only 1 trillion, and it can be opened directly without installation.

When opened, there is a guided tutorial.

"Step 1: Turn on the camera; Step 2: Record a set of actions; Step 3: Repeat the action; Step 4: Save as a library ......"

After reading the tutorial from beginning to end, Zhang Qiu understood that the main function of this software is to identify specific people through a set of specific actions.

This is the function, but the use can be infinitely expanded. Zhang Qiu's first thought was encryption, encrypting his computer.

This engine is not very large and can be easily infiltrated into any software and system. When the time comes, the system with the embedded motion recognition engine will not be opened unless you come by yourself.

Thinking of this, Zhang Qiu couldn't help but be a little excited. If he can understand this engine, his safety skills will be upgraded to a higher level as a whole.

Zhang Qiu immediately opened the source code and read it, this is a software written in assembly language, fortunately, with Zhang Qiu's world-class computer level, it doesn't look difficult.

After reading it, Zhang Qiu couldn't help but be a little excited, he actually understood the truth on this source code, but to combine these, it required great creative power. Just like the invention of the invention of Zào, in fact, the principle is very simple, and the technology can be easily realized, but before it was invented, no one thought that it would be so simple.

There are some unexpected architectures in this engine, but Zhang Qiu can understand all the principles and technologies involved. It means that they have appeared on Earth, or have been used in other ways.

Regarding the technology of character recognition, it has long appeared on the earth, such as the very popular image search and face recognition on the search engine, which is used in this technology.

The text recognition engine uses similar technology to the one mentioned in the action recognition engine.

For example, some companies use face punching in and out of work, gesture operation of some engineering systems, smiley face detection on camera, etc., all use this technology.

Zhang Qiu also downloaded several existing related software and decompiled and analyzed it, and found that these software were very backward compared to the system reward.

The functions are still those functions, but in terms of integration strength, the motion recognition engine has completely blown up the software on the market. On the optimization process, it is more of a heaven and an underground.

Generally, there are related functions, and the software involved in this aspect of technology, whether it is text recognition, face recognition, or smiley face detection, is either too bloated and consumes resources, or it is too simple and imperfect.

The motion recognition engine, on the other hand, has achieved a perfect balance between simplicity and functionality.

The program architecture and algorithms involved in it are comprehensively superior to those programs on the market today. In particular, the algorithm has unique characteristics. Some unnecessary comparison operations are greatly simplified, and the necessary comparison operations are accurately extracted, and high-precision recognition can be carried out with a small number of operations.

Think about it, if there is no leading breakthrough in algorithms, optimization alone will not be able to alleviate the hardware requirements. After all, the total amount of computing is there, and so is the computing performance of the hardware. With the same total amount of calculations, no matter how much you optimize, it is very limited. The execution steps can be optimized, but the actual operation cannot be optimized.

Therefore, the action recognition engine simply optimizes the algorithm and reduces the total amount of operations. In this way, the amount of computing required to complete the same task is greatly reduced, and the requirements for hardware are naturally greatly reduced.

Delete the miscellaneous software that was downloaded, Zhang Qiu saved the source code to the USB drive, thinking about when to print it out and save it physically, so as not to lose it accidentally.

However, confidentiality is also an issue if it is to be printed. The best way to do this is to eat the source code thoroughly and save it in the form of memory.

After acquiring world-class computer skills, Zhang Qiu has an amazing reaction speed and memory ability when it comes to computers. So it's no problem to write down all the source code.

Zhang Qiu's first research was encryption, and it took about an hour for Zhang Qiu to embed the motion recognition engine into a compression software. In this way, the software that is compressed in the future can choose to use action recognition encryption.

However, Zhang Qiu does not have a camera yet, so he can't verify one or two.

With this experience, Zhang Qiu began to try to embed the motion recognition engine into his Linux system to further ensure the security of the computer.

He spent hours fighting for it all night, and he succeeded. However, all of them suffer from the lack of cameras, so they cannot be thoroughly verified.

Fortunately, in terms of program logic, there are no problems. Zhang Qiu also used hacker methods to try whether he could bypass the motion recognition engine.

At the beginning, Zhang Qiu still found several loopholes that could be bypassed. As soon as he finds a loophole, he immediately changes it and remediates it until it is completely eliminated. Most of those hours were spent testing the vulnerability, and by the time it was officially completed, with his world-class hacking skills, he couldn't bypass the motion recognition engine.

The next thing to do is to get a camera and verify that it can be cracked from the program itself. For example, whether this action can be imitated by another person, so as to achieve the purpose of cracking. These involve the accuracy of the program, but Zhang Qiu believes that the products produced by Someiyi must be high-quality, and the accuracy will not be a problem.

Before the morning run the next day, Zhang Qiu was walking on the way to the morning run, and suddenly remembered to verify the new active radar. opened the interface, saw Lin Lai in the list of girls that had been associated, and clicked the detection and positioning button with excitement.
