Guqi Municipal Bureau.

In the evening, the setting sun reflected the red glow, which illuminated the thick clouds.

Following Gao Changjiang's order, the originally quiet courtyard of the Municipal Bureau became boiling in an instant.

Hundreds of policemen came out of nowhere, from upstairs, downstairs, from the basement, and from corners and crevices, and lined up in the yard with complete equipment.

Gao Changjiang put on his training uniform, bulletproof vest, and a gun holster around his waist, looking down as if his whole body was burning with black fire.

"Four children under the age of 5 were listed by the ministries and commissions, and the leaders at all levels cared and urged them. I don't need to remind you how important the case is. Now I assign tasks, and the units and individuals who receive the tasks should not claim credit. , don’t back down, don’t be afraid of difficulties and sacrifices, you must do your best to complete the task, even if there is a knife in the sky, you are carrying the corpse of your comrade-in-arms, you will complete it for me!”

Gao Changjiang held a loudspeaker in his hand, his voice was loud and clear, and there was even more force in his orders.

Jiang Yuan looked at both sides in surprise, and then asked Dong Bing next to him: "Is this how your high-level games are usually like?"

"Small cases are definitely not. For big cases, high-level bureaus are like this." Dong Bing replied in a low voice.

Jiang Yuan said "Oh".The current police force is not afraid to sacrifice such slogans, and they are shouting less and less.

This Chief Gao Changjiang, when he was doing case analysis, was like an ordinary police leader, even a little weak.I didn't expect that when I was ready to fight, I was in high spirits and my courage doubled.

With 35 years of experience in boarding with relatives, Wu Xia understood Jiang Yuan's thoughts, chuckled, and said, "The Gaoju used to be in frontier defense, but later he was transferred to other places."

"No wonder." Jiang Yuan nodded in relief, and then looked at the criminal police officers of the city bureau, who received the order and set off as if they were going to the battlefield.

The latest news, like flowing water, kept pouring in.

"The mobile phone of the suspect has been identified, and the number is now being sent."

"Several people are confirmed."

"Their next stop is likely to drive all the way out of the provincial border, and then at the intersection of Xinming Township Expressway in Xingfeng Province. Xinming Township has their dens."

"The total number of people in this gang may be more than 30 people. The exact number and the leader of the gang are still uncertain..."

A criminal gang is like an isolated island. Before there are no coordinates and no location, it is a long and lucky exploration to find an isolated island. But after finding an isolated island, or even boarding an isolated island, information suddenly becomes cheap and plentiful. stand up.

The next question became how to successfully capture the isolated island and reap as many fruits of victory as possible.Or, bury the dirty fruits.

After listening to the reported information, Jiang Yuan and several experts turned to a leisurely data-checking stage.

It wasn't until the number of the 30-person gang was reported that they drew a little attention.

"This is a medium-sized gang, and it is likely to be scattered all over the country. The previous work of investigating old cases can continue." Zhang Xian arranged a sentence with experience.

Jiang Yuan nodded, without saying anything, Mu Zhiyang and others started to move by themselves. …

Next to it, the criminal police of Guqi City also became busy.

Jiang Yuan looked at the case by himself, and couldn't calm down for a long time.

Trafficking of women and children was a period of high incidence in the 90s, and the ministries and commissions organized four consecutive nationwide anti-trafficking campaigns, with remarkable results.By 4, the cases of abduction and trafficking of women and children had plummeted to about 2000 a year.But since 2000, such cases have continued to occur frequently.

Moreover, the scale of various kidnapping gangs tends to increase, and the chains formed are getting longer and longer. Multiple resales are a common phenomenon. Criminal members have also begun to use single-line contacts, and the degree of specialization has increased significantly.

In Jiang Yuan's view, greed for profit and low punishment are complementary to each other.

Members of abduction and trafficking gangs generally have low education and low income, and most of them are women

It is basically impossible for these people to find employment after being punished.Nowadays, cleaning and nannies in the city require no criminal certificates. Obviously, it is difficult for these people to show a strong technical level, so that the unit can pinch their noses to store them.

The rest is nothing more than farming or self-employment.The latter is equivalent to starting a business, and it is not so easy.

In the end, this group of kidnapping gang members who have received re-education in prison will find that it is quicker and more comfortable to get money from trafficking women and children, especially children, which require almost no capital, just a few tickets and a few days of accommodation fee, you can complete a transaction and earn tens of thousands of dollars.

Not only that, these ex-criminals who have received the iron fist of the dictatorship, once they decide to continue their criminal career, become the backbone of the criminal gang. As long as a few such gang members, they can support a dozen or even A large group of dozens of people.

The anti-trafficking boom in 00 ended, and the abduction and trafficking gangs reignited in 07. It is hard to say how many gang backbones are hidden among them.

"I suggest that you can determine the appearance of these gang members in advance. Can you find their photos?" Jiang Yuan looked at Director Wang who was doing video tracking.

"As long as there is someone, it's easy to find someone." Director Wang smiled. His specialty is to track the movement of suspects or anyone through video, which is equivalent to an electronic dog.

This work seems to be a matter of course in film and television works. Once it is shown on the big screen, the camera will follow the suspect wherever he goes. In fact, this is naturally impossible.Cameras always have blind spots, broken cameras, places where there are no cameras.

Most importantly, the networking of cameras is a big project in itself.Cameras of different ownership are rarely combined into one system. This is either a permission issue or a technical issue.

All in all, even if it is tracking a vehicle, it needs a special person to intervene in order to follow it, and it is even more difficult to refine it when it comes to people.

"I'll help you later." Jiang Yuan gave Director Wang a word, and then looked at the social media information gathered by other people.

Director Wang said "En" and didn't take it seriously.

Jiang Yuan may indeed be excellent in trace inspection, surprisingly excellent, but what role can trace inspection play in terms of video? If he really wants a staring "observer", he would rather have Dong Bing like this.  …

Jiang Yuan released Director Wang for the time being, and started chatting with the suspects himself.

After confirming the mobile phone number or account number, the relevant content can be retrieved directly from the backup server. For the police, it is the main job to quickly search for useful content.A common example is to determine the group of criminals. If there is a group chat to buy food, you can use the address of the food to determine the residence of the suspect, or.
There is a lot of information extracted, and if it is useful, it will be sent to the front line. If it is necessary to further investigate, there are other front-line personnel who can be dispatched.

The advantage of cases listed by ministries and commissions is that there will be no shortage of resources and manpower. In theory, with these two things, 99% of cases can be solved.It's just a matter of time and degree of difficulty.

Soon, Director Wang pulled out the images of the first batch of personnel.

When Jiang Yuan heard the noise, he took the initiative to look over, and sure enough, he saw the two assistants brought by Director Wang, humming and humming.

The monitoring of face-to-face is greatly affected by oneself and the environment.On the one hand, it is exposed to the outside, wind, frost, rain, snow or smog will affect the clarity of the image.

Furthermore, the clarity of the monitoring screen itself is also limited.There is no need for metaphors, the difference in picture quality between 4K resources and 1080P resources or 240 resources is obvious to all.The monitoring equipment is installed one after another. In some places, the blue control that has been dry for 10 years is still in use, and the investment in different places is also different. Naturally, it cannot be generalized.

In addition, distance is also a decisive factor. With the same image quality, shooting a human body within 1 meter is definitely different from shooting a human body 100 meters away.

All of the above can be partially or completely solved by image enhancement technology.

Director Wang
As an expert in image tracking, he obviously attaches great importance to related issues. The younger brother he brought in worked hard and kept pulling out various frames and command lines. Among them, the main one is a technical bull with LV2 and above.

In the field of image enhancement, technicians whose technical level can reach LV2 are already extraordinarily expensive.

As for the two technicians brought by Director Wang, the image enhancement technology is at LV2 and above, obviously recruited by the society. Although the other one looks like he came out of a police academy, his image processing ability must also be at LV1.5. [-] now.

The cost of raising such two people is probably more expensive than a squadron of police dogs.

Jiang Yuan patted the weaker technician on the right shoulder on the shoulder, and said, "Make room."

He has been selling outside for a long time, and he is very used to dealing with people from other units. Sometimes, when describing his ability and technology in words, and the technical gap with the other party, the other party will often think that you are insulting him.

On the contrary, it really started to operate. When the technology of the two is compared horizontally and is very remorseful, normal people are often very calm.

The technician brought by Director Wang, which is equivalent to about one-third of the cost of a police dog squadron, stood up a little dazedly. He was not quite sure what Jiang Yuan wanted to do.

Jiang Yuan sat on his chair without hesitation, and began to operate with a bang.One third of the technicians of the police dog squadron were stunned, and looked to Director Wang for help.

Director Wang actually noticed this side, and walked over slowly. …

At this time, Jiang Yuan has officially entered the process of image enhancement.He just paid attention to the software used by one-third of the dog skills, paid a little attention to the version, and easily entered the state.

When Director Wang came over, Jiang Yuan had already processed one frame of the image cleanly.

This photo is from a car rental company and was recorded by the surveillance camera in the parking lot. The quality of the image is average, and the face can be distinguished, but it is a bit difficult to see clearly and use it to recognize people.

However, Jiang Yuan used the method of filling in noise, and even enlarged the face.

"Are you sure?" Jiang Yuan saw that Director Wang was coming, and politely asked his opinion.

Director Wang is an expert in imaging, and he is also a person who knows the goods. He leaned over to the computer and looked at it for a while, and then he couldn't help but look at Jiang Yuan: "You can also enhance the silent image?"

"Know it a little bit," Jiang Yuan said, and suddenly called up the command line, and typed in a row of functions--in fact, this is not necessary at all, just to prove the strength of the image enhancement LV5.

The expressions and attitudes of Director Wang and his two assistants suddenly became very soft, like the strong people who have eaten LV5 dog food.

"Let's work hard and try to fix the images of the members of this gang." Jiang Yuan seemed to be a navy captain who had landed on a pirate island and started counting heads.

Dong Bing, the only policewoman on the scene, suddenly said in a voice that only Tang Jia could hear: "Ningtai Jiangyuan, no wonder."

Tang Jia rolled her eyelids, and thought to herself: How can there be a policewoman with such a voice.
