Chapter 142: Entering the Warehouse

The next day.

The sky is high and the air is crisp.

Feeding Dazhuang.

Stroking the dog.

During working hours, Jiang Yuan went to the office area of the Economic Investigation Brigade.

Wei Zhengguo also arrived at the same time, just meeting at the door.

"Coming quite early." Wei Zhengguo laughed.

He is quite willing to help Jiang Yuan. He even feels that it is rare to be able to help Jiang Yuan, so he is extra active.

Jiang Yuan smiled like a student and said: "Leave a good impression on others."

"Actually, no need, besides, we are also helping him." Wei Zhengguo said, taking Jiang Yuan inside, also smiling all the way, greeting everyone.

In the office area in the morning, police personnel were coming and going, all staring at Wei Zhengguo, and someone asked questions from time to time.

Fortunately, the economic investigation police officer came out to greet them, at least saving two rounds of questioning time.

"Introduce, this is Li Suigong. Deputy Captain of our Economic Investigation Third Squadron." Wei Zhengguo said, self-deprecatingly adjusting the atmosphere: "Same as me."

Li Suigong smiled: "What is there to say about the title of deputy captain. Wu Wu Fa Yi Jiang doesn't need to be introduced, long heard of the name..."

"Let's look at the case directly." Wei Zhengguo laughed twice, also feeling that it was not very suitable for small talk.

Li Suigong then took the two into the office, and while turning on the computer, said: "You should understand the basic situation of the case. We also just took a statement from the victim, and now we are waiting for the news from the criminal science center in Changyang."

"Do you use fingerprints to determine identity?" Jiang Yuan asked.

"Generally not. Because people can't be found." Li Suigong explained: "The difference between this kind of contact-based economic case and criminal cases is that the criminal suspect can be contacted in the early stage, it just depends on what method is used to confirm his identity."

Jiang Yuan listened and nodded, indeed so, criminal cases are usually not knowing who did it, and need to find someone.

Economic cases are different, actually knowing who did it, just need to confirm the real identity of someone.

"We usually confirm people through DNA and photos. DNA is relatively accurate, and the speed is fast. As for photos, using facial recognition, and then through portrait bayonet, often you can find people directly."

Li Suigong said here, looked at Jiang Yuan, and said: "Now DNA and photos have been sent to Changyang City, and they are stuck and haven't been processed. We have to wait for the processing to be done before we can continue here."

Jiang Yuan heard photos and facial recognition, and immediately became energetic, asking: "How do you process your photos?"

"Just meet the requirements of facial recognition."

"What are the requirements for facial recognition?"

"That is, the facial features are clear, like a headshot is the best. Of course, if the general conditions are not met, the matching rate will be lower. The clearer, the higher the matching rate."

"Matching with where?"

"Mainly the portrait bayonet, right?" Li Suigong pointed outside the window and said: "Just like the vehicle bayonet, now many cities, especially high-speed railway stations and airports, have portrait bayonets. By then, take the photos we have in hand and compare them with the photos taken by portrait bayonets in various places, it will be relatively easy to find the criminal suspect."

Actually, it is the static version of facial recognition.

It is not easy to recognize someone when people are moving.

But if you take a photo of everyone passing by, and then compare the photo with the photo, isn't it simple?

Facial recognition and portrait bayonet are just such a simplified idea.

Jiang Yuan basically understood, and said: "Can you let me see your photos here?"

Li Suigong hesitated for a moment and said: "Look, just take a look. These photos are also taken by your criminal science squadron. They are all surveillance photos."

As he spoke, Li Suigong found several photos from the computer folder.

Jiang Yuan looked at the screen, all photos taken by high-definition cameras, the imaging clarity was quite good. If you distinguish with the human eye, seeing the face clearly is no problem.

"This clarity is not enough?" Jiang Yuan asked if he didn't understand.

"Facial recognition mainly looks at the face. Moreover, we do it a bit clearer here, and the probability of recognition will be high. Otherwise, when it is thrown into the blacklist library, there will be no news for a long time, and this clue will be yellowed." Li Suigong said it very practically.

Jiang Yuan nodded slowly. The case was not big, and sending it to other provinces and cities to enter the warehouse could only wait statically. It would only be reported to this side after the system recognized it and it was manually confirmed.

Vague, everyone is difficult.

If a false alarm is really made, it is still oneself who is tired.

Therefore, one must do a good job here first. The clarity of one's own face is high enough, and comparison is easy.

Jiang Yuan thought of fingerprints from this.

Fingerprint comparison, one side is the criminal suspect's fingerprint, and the other side is the accuracy of fingerprint collection. The level of fingerprint collection in Ningtai County has never been high, and one must really ponder this in the future.

Jiang Yuan's divergent thinking scattered and gathered, and his eyes gathered on the picture in front of him again.

"You just said that the pictures were sent to Changyang City? What is the finished product they made? Can you let me see it?" Jiang Yuan made a request again.

He could actually see a pile of folders with different names at his hand, but without the owner's permission, it was obviously not good to click.

Li Suigong looked at Wei Zhengguo with a wry smile, and then said: "Your request is one after another. Okay. I happen to have a case here before, and the criminal was also on the news later. I will find it for you."

He picked up the mouse again, picked and chose, and released new pictures.

Sure enough, it was a headshot.

"Made by the provincial department's image investigation brigade?" Jiang Yuan asked while looking.

"Right. This can be considered very well done, and it is also a relatively big case, specifically told the other party, and strengthened it twice." Li Suigong sighed.

Ningtai County doesn't have an image investigation team, so it can only ask for help, and this part is often the most emotionally consuming place.

Jiang Yuan listened and nodded.

With comparison, he understood.

What the image investigators do, saying it is simple is also simple, that is, extract the head portrait of the criminal suspect from the surveillance screen or photos first, and put it aside separately.

If the resolution of the head portrait, etc., meets the requirements, this can be used directly. In most cases, it is obviously not possible.

So, the second step of processing is to enhance the image, remove noise where noise should be removed, and repair where it can be repaired.

Jiang Yuan has also seen the level of the provincial department's image investigation, which is basically the appearance of being less than lv2.

As mentioned before, those who really have the level to do images and develop portrait bayonets have both face and inside.

"I'll do this picture." Jiang Yuan had long been prepared to take over the work, just now he was looking at what the specific requirements were.

"I Have a Scroll of Ghost and God Illustrations"

Li Suigong looked at Jiang Yuan suspiciously, and then looked at Wei Zhengguo.

Wei Zhengguo was calm, his expression relaxed, and said: "Second-class merit."

"Get, then how do I give you the photos?" Li Suigong didn't talk nonsense when facing "second-class merit."

There are actually quite a few people with second-class merit in the criminal police. With the configuration of the Ningtai County Bureau, one can be rotated every year or two.

However, it is quite rare for those in the criminal science and technology squadron, or technicians, to be able to get second-class merit.

Li Suigong is not sure where Jiang Yuan is strong, but since people dare to take over, he doesn't mind copying and pasting.

Jiang Yuan looked at the picture and said: "You put it on the intranet, I will operate it directly on my phone."

"Can it be done on the phone?" Li Suigong was surprised.

"I operate the computer with my phone, wait a moment." Jiang Yuan had installed the relevant software early on.

And just enhancing the clarity of the face, this requirement is indeed not high.

Ordinary people training for a few days can actually operate it.

Like in the provincial department's image investigation brigade, it is not that everyone can reach the level of lv2. What ordinary team members do is actually operate software and work step by step.

Jiang Yuan sat on the side, and in a few minutes, completed the enhancement of the image.

He didn't use any special methods, basically the software did it fully automatically.

The retrieved image was put back into the intranet and opened on the computer. Sure enough, it was already a presence that was several levels clearer.

"You did this... it's really okay." Li Suigong's eyes lit up.

"Can this be sent over?" Jiang Yuan asked.

"Of course, this clarity is enough, quite enough." Li Suigong answered repeatedly, and sat down and said: "Wait a moment, I will send the picture to the blacklist library."

Jiang Yuan and Wei Zhengguo waited on the side.

Li Suigong was afraid that the two would be bored, and while doing things, said: "Now in the blacklist library, there are high-risk personnel, special personnel, and those handed over by different units, which is quite complicated, but the efficiency is okay..."

"Will the criminal suspect be warned if they pass through the portrait bayonet?" Jiang Yuan asked.

"Almost means this. Those passing through the bayonet will be captured, and if they are compared, they will be reminded, and then manual identification will be done here, and then they can be reported." Li Suigong said: "Generally, as long as the initial location is determined, it is relatively easy to find people later."

"That is to say, we still need to go over later."

"Not necessarily. For example, the portrait surveillance checkpoint at Changyang Airport alarmed, and then confirmed that the person got on the plane, then please cooperate with the police at the destination. Of course, we generally send people ourselves." Li Suigong smiled.

Wei Zhengguo smiled understandingly, economic investigation, what is caught is money.

Li Suigong finished quickly here, clapped his hands, but said: "Wu Wu Fa Yi Jiang, that, I don't know if you are still busy here."

"Not busy, you say." Jiang Yuan heard the string and knew the elegance.

"En, a bit embarrassed, but I still have a lot of pictures pressed here, can I ask you to help process them?" Li Suigong is now believing in the person of "second-class merit."

Jiang Yuan agreed, only saying: "If it is batch processing, I have to go back to the office to do it."

"No problem, no problem. I will send it to the intranet now?"

"Good." Jiang Yuan agreed, and returned with Wei Zhengguo.

Li Suigong sent the two out enthusiastically, and said: "If there is news about the case, I will notify you!" ===== CHAPTER 143 =====
