Chapter 521 The problem of simulated portraits

Provincial People's Hospital, Interventional Ward, when Xu Zheng and others walked in, Professor Chi Guoming was standing in front of the window chatting with a doctor wearing glasses and a white coat. When the doctor turned around, it turned out that it was the doctor who had just

Fu Xuerong was promoted to director of the interventional department.

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

When Chi Guoming saw Director Nie coming in person, he hurriedly stepped forward and asked, "Why did Director Nie come in person? Is there any clue about my matter?"

Director Nie held Chi Guoming's hand and said with a smile: "Based on our investigation results and with the approval of our superiors, we will not prosecute. However, within these three months, I hope that Professor Chi will not leave Changming. If he must go out,

, For example, if you want to treat a disease, just report it to us."

"Alas" Chi Guoming sighed, looking haggard, "To tell you the truth, I only have one month left in three months."

Fu Xuerong, the new director of the interventional department next to him, looked bitter, "I was just trying to persuade the teacher that his disease can be operated on. If the operation is effective, he can still live longer."

"No, no need." Chi Guoming said cheerfully: "The operation is very effective. It is indeed possible for me to lie down in the hospital bed and survive for a year and a half, but I cannot speak or get out of bed. I live by injections and infusions every day.

This is contrary to my philosophy and I don’t want this.”

Chi Guoming's children are married and his parents have passed away. The only one who has some memories is his wife. However, most couples who are doctors do not have a good relationship and live a makeshift life. Therefore, he has no desire to persist in living.

Moreover, living in pain is indeed not a philosophy he has always adhered to.

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

Chi Guoming only found out in the past few days that his affairs had affected Xu Zheng's work. He was filled with guilt, held Xu Zheng's hand, and said slightly excitedly: "I didn't expect that my affairs would affect your work."

, and you can’t even work as a detective.”

Xu Zheng interrupted him quickly, "No, no, Professor Chi. On the contrary, I changed my job this time and got promoted. As for being a criminal police officer or not, any job is a good job as long as it can catch bad people."

After all, this was not the place to talk. Director Nie and Team Wan chatted with Professor Chi for a while before taking their leave.

As soon as he left the ward, the system's voice rang in Xu Zheng's mind, and it rang several times in succession, "Ding, congratulations to the host for completing the hidden kill list mission."

[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 time for the system’s hidden kill list is six months. The host can complete various cases to speed up the cooldown of the hidden kill list.]

Xu Zheng was surprised and delighted by the sound of the three-tone system. He was surprised because he was surrounded by leaders, but he was delighted because of the new abilities given by the system.

Advanced voice talent.

The system is indeed a considerate person and knows that he needs to learn various dialects. With this ability, it will no longer be as difficult as learning English in school.

It's just that this ability is a bit unworthy of the name for ranking ninth on the system's hidden kill list. He thought about it, it should be Professor Chi's case. He didn't put in much effort, including the investigation of Professor Chi's hundreds of patients, all the work was sent by Wan Detachment.

Investigating secretly.

It seems that what the system rewards does have a lot to do with his own participation in the case.

There were a lot of people in the elevator. Director Nie and Team Wan clearly felt something was wrong with Xu Zheng, but they didn't take it to heart. They just felt that this guy was a little obsessed with investigating the case.

How could Zhou Youfang and Jiang Lanxin's children be abducted? How could it be so easy to investigate? Face recognition, various high rewards, and interrogation of hundreds of traffickers. The anti-trafficking offices in various provinces have exhausted all their methods, but they have not been able to find Xu Zheng for so many years.

Finding new clues this month is as difficult as going to heaven.

But having said that, if you are not a madman, you cannot become a Buddha. The investigator who is obsessed with the case has to be in this state. Occasionally, even in a dream, an idea flashes, and this clue comes.

On the way back, Director Nie admonished Xu Zheng, "Are you going on wedding leave starting tomorrow? When you get back, prepare for the wedding. Let's continue investigating these two kidnapping cases after your wedding leave is over."

Wan Haihong also meant the same thing, "Your family is basically worried about your wedding. Work more after you go back. You can't do work secretly."

With your temperament, if you are at work, good guy, you will definitely forget about food and sleep, and your wedding will be delayed, which is a big deal.

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

Xu Zheng could only giggle. He is such a person. When he works, he will really forget the time and indulge in the idea of ​​​​solving the case. Outsiders find it boring, but only people like them will feel that the flash of light is also a

kind of happiness.

Back at the detachment, Xu Zheng got into a small conference room again. He was too lazy to go back to his desk now. He even stopped attending the morning meeting and devoted himself wholeheartedly to the files on the anti-kidnapping case.

This time, he unknowingly opened the file of Jiang Lanxin's daughter Yan Mo. The girl was two years old when she was lost. At about 11 o'clock in the morning on February 16, 2022, she was killed at the Tianhaoling Temple Fair in Longkou City, Zhongping Province.

People abducted.

The Tianhaoling Temple Fair has an average of 400,000 visitors per day. After her child was lost here, Jiang Lanxin immediately shouted to passers-by for help, but the crowds were so overwhelming that her and her husband's voices were drowned in the crowd.

The police who were on duty at the temple fair arrived at the scene within three minutes, but there were so many people coming and going. What was disappointing was that when the child was lost, none of the passers-by standing nearby came forward to testify or provide clues.

What's even more pity is that there are no cameras on this stretch of road.

Although the local police collected videos within an hour after the child was lost, they watched the videos hundreds of times and found no suspicious person, let alone any trace of the child after he was lost.

Xu Zheng has been looking through the thousands of hours of video these past few days. He has basically finished watching it. He originally wanted to ask for help from the picture detectives of the picture detective detachment, but this case is not the case of the detachment. This is

His personal matters.

It's definitely not okay to use police force to handle his personal matters during working hours.

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

The little girl who is now 12 years old, with her adoptive parents, can recognize her appearance through facial recognition unless she is seriously ill or has no accidents such as disfigurement.

Unless the child encounters some unexpected circumstances.

A serious illness in childhood may affect the child's appearance, especially when the child's teeth are changing. For example, if the child has a mouth full of cavities, this will definitely affect her appearance when her teeth are changing.

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

Xu Zheng thought of this and patted his forehead. Is it necessary to conduct a nationwide investigation on the little girl who had cavities on her teeth seven or eight years ago?

This is simply fanciful. To check these, it would be better to register the DNA of all people.

However, this idea also gave him new inspiration, that is, what would dental caries make of this little girl? In this regard, he drew some photos of her 12-year-old based on the photos of two-year-old Yan Mo.

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

After all, children's school status nowadays is all online. There is a photo on the school status, which can definitely be checked under the national network.

It has not been found now, which means that the girl Yan Mo has changed a lot since she was a child.

At present, Xu Zheng feels that changes in appearance caused by dental caries are also one direction. The other reason is that Yan Mo suffered a serious illness after being abducted, such as general anesthesia, which can also affect appearance.

Also, for example, if she is from the Central Plains and is suddenly abducted to Yunnan-Guizhou and other places, her appearance may change due to unsuitable soil and water conditions, as well as environmental and other factors.

Although Xu Zheng now has advanced simulation portrait technology, he has never drawn this kind of portrait before. It is impossible to draw and there are too many changes. But now he wants to give it a try. After all, face recognition has been able to help the police since its advent.

Many abducted children were found.

For example, ten years ago, the Mr. Guo's abducted son was found by the Trung Binh Province police using facial recognition technology.

This kind of research requires considering various factors that lead to changes in a child's appearance as he grows up. He certainly cannot do it alone, he will need helpers.

Zheng Heming from the Provincial Picture Scout Corps and his apprentice Qi Guangyuan from the Municipal Picture Scout Detachment are both good simulation portrait masters. I wonder if they would be interested in coming to help.

Thinking of this, Xu Zheng did not hesitate and directly picked up his mobile phone and called them. As expected, both of them were interested in the topic Xu Zheng talked about, especially Zheng Heming, who had been working for almost thirty years and still

Really researched it.

He was very interested in the phone call and directly invited Xu Zheng to his studio. There were materials he had collected over the years. He was now studying it as a topic. His superiors even approved him a million research funds every year, but

, since his project was established five years ago, no results have been produced for so many years.

This time Xu Zheng happened to coincide with his topic. Before the phone was hung up, Zheng Heming hurriedly assured Xu Zheng, "Xiao Xu, just come to my place. I will personally call Director Nie to ask for leave."

Naturally, Xu Zheng didn't let him make this call, because he was now a free agent of the second brigade, and he didn't even need to tell Zhang Yuqi when he went out to do errands. However, when he went out, he still went to the brigade captain's office to inform him.

Zhang Yuqi was studying the case with her head down at this time. As the investigation of the 2.14 case became more and more in-depth, the Second Brigade found out that the murderer may have used psychotropic drugs and hypnosis to commit the crime, but there was no trace of the murderer behind the scenes.

Therefore, everyone has a sad look on their face these days.

When Xu Zheng said he was going to the provincial department to handle matters, Zhang Yuqi nodded and waved him away, but finally asked out of curiosity, "How is the anti-trafficking case you investigated going? Can it be solved in a month?"

Xu Zheng smiled mysteriously, "I went to the provincial office to verify my guess. There is a 50% chance of success this time."

Zhang Yuqi was immediately interested. 50% was already a very high probability. "What's the situation? Can you tell me in detail?"

"I'll give you a break first. If it doesn't work, I'll slap you 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, "Get out of here and wait until you have the exact information."

From the Pingjiang Provincial Public Security Department in Qinhuai District, Xu Zheng came with Qi Guangyuan. The two had a brief exchange on the road. He first gave Xu Zheng a brief introduction to Zheng Heming's topic.

The main purpose is to study the abnormal appearance changes of children during the entire growth process. He said: "In fact, the forest expert from Shandong Province studied this topic, but gave up. Later, he mainly studied the combination of simulated portraits and blurred portraits.

New method solves the problem of unclear portraits in surveillance videos.

However, although he did not continue to study this topic, he still gave me a lot of suggestions as a teacher.

Maybe this subject is indeed very difficult, or maybe we people are not talented enough. After so many years, we have basically stagnated.

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

We have also cooperated with software development companies, but 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 this."

Xu Zheng scratched his eyebrows and said, "Lao Qi, I want to back off what you said. There are so many of you masters and apprentices, and your teacher is still a senior engineer in our Pingjiang Provincial Department. I feel that having one more of me is a waste.
