I don't want to solve the case when I'm a little policeman.

Chapter 521 The Difficulty of Simulating Portraits

Provincial People's Hospital, interventional ward, when Xu Zheng and the others walked in, Professor Chi Guoming was standing in front of the window and was chatting with a doctor wearing glasses and a white coat. Fu Xuerong, who was promoted to the director of interventional department.

It is said that he is still a student of Professor Chi Guoming.

When Chi Guoming saw Ju Nie coming over in person, he hurriedly stepped forward, "Why did Ju Nie come in person? Is there any clue about what happened to me?"

Director Nie held Chi Guoming's hand and said with a smile: "According to our investigation results, with the approval of the superiors, we will not prosecute. However, within these three months, I hope that Professor Chi will not leave Changming. , such as treatment, just report to us."

"Ah..." Chi Guoming sighed, with a haggard look on his face, "To tell you the truth, three months, I guess it's only one month."

Fu Xuerong, the new director of the interventional department next to him, showed bitterness, "I was just trying to persuade the teacher that his disease can be operated on, and if the operation works well, he can still live longer."

"No, no need." Chi Guoming said open-mindedly: "The effect of the operation is good. It is indeed possible for me to lie on the hospital bed and live for a year and a half, but I can't speak, I can't get out of bed, and I live by injections and infusions every day. It's against my philosophy and I don't want to do that."

Chi Guoming's children are married and their parents have passed away. The only person who remembers him is his wife. However, as a doctor, most of the couples don't have a good relationship.

Moreover, living in pain is indeed not the philosophy he has always insisted on.

Xu Zheng took out the release document issued by the Municipal Bureau and handed it to Chi Guoming with both hands, "Professor Chi, take care!"

Chi Guoming only found out in the past few days that his affairs have affected Xu Zheng's work. He was full of guilt, held Xu Zheng's hand, and said a little excitedly: "I didn't expect my affairs to affect your work. , and make you unable to even work as a criminal police officer."

Xu Zheng hurriedly interrupted him, "No, no, Professor Chi, on the contrary, I have been promoted this time by changing jobs. As for criminal police or not, as long as you can catch bad guys, any job is a good job."

After all, this is not a place to talk. Director Nie and Team Wan chatted with Professor Chi for a while before saying goodbye.

As soon as he got out of the ward, the system's voice rang in Xu Zheng's mind, and it rang several times in a row, [Ding, congratulations to the host for completing the hidden killing list task. 】

[The system rewards the host with advanced language talent. Note: Advanced language talent can improve the host's ability to learn various languages ​​tenfold. 】

[The next cooldown of the system's hidden kill list is six months, and the host can complete various cases to speed up the cooldown of the hidden kill list. 】

The three system voices made Xu Zheng both surprised and delighted. He was surprised because he was surrounded by leaders, but he was naturally delighted by the new abilities endowed by the system.

Advanced voice talent.

The system is indeed a caring person, knowing that he needs to learn various dialects. With this ability, learning English will no longer be as difficult as when he was in school.

It's just that this ability is a bit misleading for the ninth place in the hidden killing list of the system. He thought about it, and it should be Professor Chi's case. He didn't spend much effort, including the work of investigating Professor Chi's hundreds of patients. secretly investigated.

It seems that what the system rewards has a lot to do with his own involvement in the case.

There were a lot of people in the elevator, Director Nie and Detachment Wan obviously sensed Xu Zheng's anomaly, but they didn't take it seriously, they just felt that this kid was a bit obsessed with investigating cases.

How could Zhou Youfang and Jiang Lanxin's child abduction case be investigated so easily? Face recognition, various high rewards, and interrogation of hundreds of human traffickers. Finding new clues this month is as difficult as climbing the sky.

But having said that, if you are not crazy, you cannot become a Buddha. The investigator who is obsessed with the case has to be in this state. Occasionally, even in a dream, a flash of inspiration will come, and this clue will come.

On the way back, Director Nie advised Xu Zheng, "Did you start your wedding leave tomorrow? After you go back, you should prepare for the wedding. For these two abduction cases, after your wedding leave is over, you can continue to investigate."

Wan Haihong also meant the same thing, "Your family is basically worrying about your wedding, so you should work harder when you get back, and you can't secretly do work things.

With your temperament, if you work, my good guy, you must forget to eat and sleep, and your wedding will be delayed by then, which is a big deal.

If that's the case, your grandma can't blame us for using you too harshly. "

Xu Zheng can only smirk, he is such a person, once he starts working, he will indeed lose track of time, and become obsessed with the idea of ​​solving the case. Outsiders find it very boring, but only people like them will feel that a flash of inspiration is also a kind of happiness.

Back in the detachment, Xu Zheng got into a small conference room again. He didn't even bother to go back to his desk now, and he didn't even attend the morning meeting anymore, and plunged into the file of the anti-abduction case wholeheartedly.

This time, he unknowingly opened the files of Jiang Lanxin's daughter, Yan Mo. people abducted.

The average daily number of visitors to the Tianhao Mausoleum Temple Fair was as high as 40. After the child was lost here, Jiang Lanxin immediately called out to passers-by for help, but the crowd was so overwhelming that her and her husband's voices were directly drowned out in the crowd.

The police who were on duty at the temple fair at that time arrived at the scene within 3 minutes, but there were too many people coming and going. It was disappointing that when the child was lost, none of the passers-by stood by to testify or provide clues.

It is even more regrettable that there are no cameras on this section of the road.

Although the local police collected the video within an hour of the child's disappearance, they watched the video no less than a hundred times, but they did not find any suspicious person, let alone the child's disappearance.

In the past few days, Xu Zheng has also been constantly flipping through the thousands of hours of video, and he has roughly read it. He originally wanted to ask for help from the investigators of the graphic investigation detachment, but this case is not a case of the detachment. his personal affairs.

It is absolutely impossible to use the police force to handle his personal affairs during working hours.

Several colleagues from the Second Brigade wanted to come over to help him after get off work, but he also refused. In fact, he also knew that it was difficult to find clues in these videos. According to Ye Tao from the Provincial Anti-Trafficking Office, their Anti-Trafficking Office would re-watch videos like this every year. It's just the result, which is very disappointing.

The 12-year-old girl is now with her adoptive parents, and face recognition can recognize her appearance without serious illness, disfigurement or other accidents.

Unless the child encountered some unexpected circumstances.

A serious illness in childhood may affect the child's appearance, especially when the child changes teeth. For example, the child's mouth is full of caries, which will definitely affect her appearance when she changes teeth.

It is also very easy to cause dental caries in children. Excluding drug factors, you only need to let children eat candy every day and do not brush their teeth. After half a year, the child's mouth will be full of dental caries.

Xu Zheng thought of this, and patted his forehead. Is it necessary to investigate the little girl who changed her teeth seven or eight years ago and developed dental caries?
This is simply whimsical, and it would be better to have the DNA of all people registered in the register.

But this idea also gave him a new inspiration, that is, what kind of dental caries will make this little girl look like. On this point, he drew some photos of Yan Mo when she was 12 years old based on her [-]-year-old photos.

To be honest, regardless of the cause of dental caries, the photos he drew are similar to those simulated by the aging software. Obviously, this kind of photos must not work. If it works, children will definitely be found in today's society.

After all, children's school status is now online, and there are photos on the school status, which can definitely be found under the nationwide network.

If we haven't found it now, it means that Yan Mo, a girl, has changed a lot since she was a child.

Looking at it now, Xu Zheng thinks that the change in appearance caused by caries is also a direction. The other reason is that Yan Mo fell into a serious illness after being abducted. For example, general anesthesia will also affect his appearance.

Also, for example, if she is from the Central Plains, she was suddenly abducted to Yunnan, Guizhou and other places. The unsuitable water and soil, plus environmental factors may also cause changes in her appearance.

Although Xu Zheng now possesses advanced analog portrait technology, he has never drawn this kind of portrait before. There are too many changes, but now he wants to give it a try. After all, since the advent of face recognition, it has helped the police Many abducted children were found.

Like the Mr. Guo ten years ago, the abducted son was found by the Zhongping Provincial Police using face recognition technology.

This kind of research that needs to consider various factors that lead to changes in the appearance of children during the growth process, he alone is definitely not enough, he needs help.

Zheng Heming of the Provincial Graphic Investigation Corps, and his apprentice, Qi Guangyuan of the Municipal Graphic Investigation Detachment, are all good simulation portrait masters. I don't know if they are interested in coming to help.

Thinking of this, Xu Zheng didn't hesitate, and directly picked up his mobile phone to call them. As expected, both of them were interested in the topic Xu Zheng was talking about, especially Zheng Heming, who had been working for almost 30 years. studied.

On the phone, he was very interested, and directly invited Xu Zheng to his studio, where the materials he had collected for so many years were now being researched as a subject, and his superiors even granted him 100 million research funds every year, but, Since he started this project five years ago, there has been no result for so many years.

This time Xu Zheng coincided with his subject, and before the phone was hung up, Zheng Heming hastily assured Xu Zheng, "Xiao Xu, you can come to my place, and I will call your Director Nie personally about the leave."

Xu Zheng naturally didn't ask him to make this call, because he now belongs to the second brigade as a free agent, and he doesn't even need to talk to Zhang Yuqi when he goes out to do business. However, when he went out, he still went to the brigade captain's office to report.

Zhang Yuqi was lowering her head to study the case at this time. As the investigation of the 2.14 case deepened, the second brigade found out that the murderer might use psychotropic drugs and hypnosis to commit the crime, but they couldn't find any trace of the murderer behind the scenes.

Therefore, these days everyone has a sad face.

When Xu Zheng said to go to the provincial department to do business, Zhang Yuqi nodded and waved him away, but finally asked curiously, "How is the abduction case you investigated, can it be solved in a month?"

Xu Zheng smiled mysteriously, "I went to the provincial office to verify my conjecture, and there is a [-]% chance of success this time."

Zhang Yuqi became interested in an instant, [-]% is already a very high probability, "What's the situation, can you tell me in detail?"

"I'll show you off first. If it doesn't work out, I'll give you a slap in the face. Don't worry, if this case is solved, it will be reported in the name of our second brigade."

Zhang Yuqi immediately lost interest and waved her hand, "Hurry up and get out, wait until you have definite news."

From the Public Security Bureau of Pingjiang Province, Qinhuai District, Xu Zheng came here with Qi Guangyuan. The two had a brief exchange on the road. He first gave Xu Zheng a brief introduction to Zheng Heming's project.

The main thing is to study the abnormal appearance changes of children during the whole growth process. He said: "In fact, the forest expert in Lu Province has studied this subject, but he gave up. Later, he mainly studied the combination of simulated portraits and blurred portraits. The new method solves the problem of unclear portraits in surveillance video.

However, although he did not continue to study this topic, he still gave my teacher a lot of advice.

Maybe this topic is really difficult, or maybe we are not talented enough. After so many years, we have basically stagnated.

Because there are too many factors that can affect the change of a child's appearance, it is difficult for us to do it artificially based on experience, and we have not found the correct algorithm for the computer.

We have also cooperated with those software development companies. Unfortunately, the data collected by normal aging software cannot be applied to the software we want to develop, so most of the funds are wasted on it. "

Xu Zheng scratched the center of his eyebrows, "Old Qi, I want to retreat from what you said. You have so many masters and apprentices, and your teacher is still a senior engineer of our Pingjiang Provincial Department. I think it would be a waste of me to have one more." time."

"Fuck, you kid can't back down. If you go back halfway, my teacher won't kill me." Qi Guangyuan was very familiar with Xu Zheng because he was doing private work together, so he spoke very casually.

While the two were talking and laughing, they arrived at the provincial office. Qi Guangyuan led the way and went directly to Zheng Heming's studio.

Xu Zheng came here for the first time. As soon as he entered Zheng Heming's studio, he felt sore, because the studio was more than 100 square meters, and his own studio was remodeled from a small storage room at home, which was less than [-] square meters. .

Sure enough, the treatment of experts is different.

But Xu Zheng's ability to simulate portraits is definitely higher than Zheng Heming's. It's just a pity that the system not only depends on ability, but also depends on seniority.

Of course, he wasn't jealous of Zheng Heming, just a little bit emotional.

When Zheng Heming saw Xu Zheng and the others come in, he immediately put down the brush in his hand, and waved to them, "Come and see how I drew this picture of autumn mountains after the rain?"

Qi Guangyuan secretly laughed at the side and said: "My teacher's eccentricity, he likes to draw landscape pictures when he is excited, and gives away to others when he is finished. You are lucky today, my teacher's paintings are worth tens of thousands of dollars per meter."

Most of the business hobbies of simulated portraitists are painting. Basically, the higher the ability to simulate portraits, the higher the level of their traditional Chinese and Western paintings. For example, the Lin experts in Shandong Province start at 20 yuan for a traditional Chinese painting.

Xu Zheng's painting ability is actually not bad. In terms of traditional Chinese painting, he has only studied portraits, and he can only speak a little about landscapes.

No, walking to Zheng Heming's desk, Xu Zheng looked at his freshly released landscape painting. He was very familiar with the landscape in the painting, which was the scene of Xiangshan Mountain in Liuhe District, so he blurted out, "Teacher Zheng's paintings are really vivid. You can recognize it at a glance, this painting is Xiangshan, right?"

Chinese painting pays attention to the idea of ​​painting, not the scenery. As soon as Xu Zheng said this, Zheng Heming realized that this kid should not have worked hard on Chinese painting, not even a teacher. Thinking about his job as a criminal policeman, he is so busy every day, so he doesn't understand much. Chinese painting is also normal.

Thinking of this, Zheng Heming lost interest in the landscape painting he had just finished drawing on the table, and pulled Xu Zheng to point to the rows of bookshelves, "Here are all the materials I have collected over the years, as for your suggestion that the tooth replacement period will affect the appearance .

I have also collected the appearance changes of several children, you can take a look first. "
