Zhou Ning hung up the phone, and Liu Yongxin came over.

"It's fast enough, the first phase of this software is basically done, right?"

Zhou Ning exhaled, he suppressed the excitement and excitement in his heart, calmed himself down, and nodded to Liu Yongxin.

When he got the fourth level of face restoration technology, he was so reluctant at first, but now he realizes that as long as one aspect is upgraded independently, the benefits he brings are unbelievable.

Because the current face restoration technology is not limited to whether it is a human face, but an analysis technology for monitoring or portraits in various very fuzzy image data.

In professional terms, it is called a face image deblurring method based on adaptive mesh deformation to improve the effect of face image deblurring.

To put it more bluntly, no matter how blurred the image is, as long as I find the position data of the facial features in the image, I can use these data to calculate the original shape of the facial features.

During the phone call just now, Zhou Ning talked about this idea, and also sent Dr. Lu detailed research steps and directions. Dr. Lu was so happy that he said that he would expand the development content of the software.

"Yes, the first phase of the design has been completed. It has been debugged and tested many times for a week. The effect is very good, and details such as skin color and iris color can be adjusted in the later stage. However, there is no suitable skull or bone fragments. Let the software simulate to restore. And what Dr. Lu means is, let me follow the past to experiment for a while."

Liu Yongxin was taken aback.

"Go as soon as you have to. It doesn't matter if I am two days early or two days late. It's just this bone fragment. Do you have any requirements?"

Zhou Ning shook his head.

"There is no requirement, but it would be better if you know the skull fragments of your appearance, so that you can make a corresponding comparison. Of course, it is also possible if the bones of the whole body are broken. This part of the bone computer analysis and restoration system is in the debugging stage, which is the second phase. Content."

Liu Yongxin blinked and approached Zhou Ning.

"So fast, it seems that Qindao University pays great attention to the development of this software, investing a lot of manpower and material resources."

"That's natural. They contacted many experts and they all got involved. However, there is a shortage of forensic science professionals now, because although the forensic medicine major is offered, these visiting professors will not participate in software research and are not suitable.

I discussed with Dr. Lu, he wants to invite you over, after all, you will officially retire in a few days, how about a letter of appointment for you? "

Liu Yongxin was taken aback, this statement exceeded his expectations, raised his finger to his face, and kept shaking his head.

"It's just me? I was just a part-time college student, but I have survived a little bit more. If I don't make it, I will be a burden to you."

Zhou Ning shook his head.

"Master, don't be humble. I think you are the most suitable one. No one can compare with experience. My tutor was highly educated back then, but those were all theoretical knowledge. What we need now is practical ability. You must know that without your persistence and Matching, this software is impossible to appear.”

Liu Yongxin blinked.

"You think I can do it?"

"There is no one more suitable than you. In fact, the research and development team originally intended to cooperate with the forensic office of the Municipal Bureau, but after a little contact, the forensic office of the Municipal Bureau is investigating a case that has been going on for many years. For a forensic doctor who is about the same age, Dr. Lu feels that it is still necessary to find a person with comprehensive skills and experience, and he thinks you are the most suitable."

Liu Yongxin smiled, rubbed his chin and leaned back on the chair.

"I didn't expect that I can rely on my apprentice to be brilliant at this old age. Since you and Dr. Lu think I can do it, I won't hold back any more. I will accept this matter."

Zhou Ning called Dr. Lu with a smile, and told about Liu Yongxin's agreement to the appointment. Dr. Lu was very happy there, and asked Liu Yongxin to wait patiently for their letter of appointment. As for the treatment, he also responded to the hospital and gave the final result .

After hanging up the phone, Zhou Ning saw Liu Yongxin leaning over to the computer, wearing presbyopic glasses and looking at something.

Zhou Ning leaned over and found that it was an email, an assisted investigation document issued by the City Bureau's Forensic Medicine Office, followed by a DNA test report. At this time, Liu Yongxin had read the last page. Seeing him take off his glasses, Zhou Ning quickly asked:
"Master, what notice did the Municipal Bureau send?"

Liu Yongxin shook his head, sighed, took a sip of tea, and then said slowly:
"It is estimated that you have been studying outside these years, so you don't know much about Qindao. There is a serial murder case in Qindao in red. In more than five years, there have been eleven consecutive crimes.

Just in this case on February 2 this year, a piece of rice green liquid was extracted from the deceased, so the DNA was sent out to ask various districts and cities to help in the investigation. "

Zhou Ning raised his eyes in surprise, the eleven serial murders were still five years old, this man is brutal enough.

"In this latest case, Mi Qingye was discovered? Didn't there be any other evidence left before?"

Liu Yongxin shook his head.

"The dead are generally discarded in garbage dumps, and the evidence has been severely damaged, and when they are generally found, the corpses are in a state of high decay, and some are even eaten by rats and wild dogs, so there is very little evidence left.

Last year, both the provincial department and the Ministry of Public Security sent people to assist in the investigation. Because the chain of evidence was missing, it was impossible to find more favorable information. Moreover, these cases usually occurred in the urban-rural fringe area around Qindao City, which was perfectly avoided. The monitoring of the city settings.

As for the fingerprints, I found some, but after searching, they were not the murderers. Most of these fingerprints were scavengers or sanitation workers. "

"What about the deceased? Haven't the identity and fingerprints of the deceased been found? Do these eleven have any common features?"

Liu Yongxin shook his head.

"The fingerprints of the deceased were all cut off. Among the eleven victims, five of them don't know their identities now. Four of the six female victims found out were high school students, commuting students. When they found out that they hadn't returned home, they contacted the school. , The body was found within three to five days after reporting the crime.

There are also two night shift girls from surrounding factories. If you want to say something in common, they are both very thin, and they disappeared at night, and they are wearing red clothes. Anyway, countless police and material resources have been invested in catching this murderer over the years. , but there has been no news.

In addition, the school requires parents to pick them up for study in the evening, and female students are not allowed to go home alone. From the end of 09 to the present five cases, the murderer has become more secretive, and the place where the body was dumped has become more remote.

The victim's face was destroyed, except for a red dress, there was no characteristic information, so the victim's identity could not be ascertained, because the missing persons could not be found.

However, I suspect that these five victims may be street girls, all of whom have shady occupations. The population is highly mobile, and most of them are not locals. Moreover, these people are not easy to be found when they are killed, so this case is even more complicated and confusing. "

Zhou Ning nodded. Liu Yongxin's suspicion was right on point. It is true that such a person is difficult to investigate during the census, and the original family rarely intervenes. If they die or disappear, the family members may not know.

Just thinking about it, Zhou Ning paused and looked up at Liu Yongxin.

"Master, are the corpses of these people preserved?"

Liu Yongxin was startled, then nodded slowly.

"Highly rotten corpses, cryopreservation is of little significance, but the bones have been processed and preserved, why do you ask this? Wait, what do you mean, this software just needs a lot of experimental data, and you want to use the software to restore them to their appearance , and then conduct an investigation?"

Zhou Ning nodded excitedly, but Liu Yongxin kept waving his hands.

"Don't think about it. There are too many people who have handled this case, and it has alarmed the provincial department, the Ministry of Public Security, and those people from the Municipal Bureau. They will not agree to participate in your software experiment."

Zhou Ning was stunned, and couldn't react for a while. If the skull was restored, wouldn't it be good for the investigation of the case? Why would he object? He should fully support it.

Liu Yongxin sighed and continued:

"I understand your kindness, and I understand it, but you have to know that we are the forensic office of the sub-bureau, and your last cooperation with the software directly crossed the city bureau and cooperated with Qindao University. Good thing, but many people have knots in their hearts, understand?"

Zhou Ning sighed, he didn't think so much, but when he thought of the two men in suits and leather shoes he met at the signing ceremony, he instantly understood Liu Yongxin's words.

"Okay, let's forget about it, but I will play the side drum with Dr. Lu later. If he thinks it is feasible, then he will discuss it with the Municipal Bureau. We will not participate."

Liu Yongxin smiled.

"Well, this is fine, but don't go looking for it right away, just go and tap your keyboard, I see that you have written a lot of pages, it seems to be a story, and there are cases we dealt with in it, are you going to publish a novel? "

Zhou Ning was a little embarrassed.

"I'm just looking for something to let myself vent my bad emotions. Didn't you say that you need to learn to untie it yourself? I think this method is very suitable for me, but I haven't decided whether to publish it yet. Master, please don't talk to other people. talk!"

"Got it, got it, I'll keep it a secret for you! But what about the hush money?"

Zhou Ning scratched his head.

"Xu Da said to invite us to a buffet last time, but he hasn't fulfilled it yet. I learned from him. When you receive the letter of appointment, I will invite you to have a good meal at the head office, right?"

As soon as the words were finished, the door of the office was pushed open, and Xu Dayuan walked in quickly.

"As soon as I came in, I heard you talking about me behind my back. What bad things did Zhou Xiaozhou say about me?"

Zhou Ning was startled and jumped off the table quickly.

"Xu Da, why are you here?"

Xu Dayuan's face was full of lawsuits, his eyebrows were almost knit together.

"Bad news, it's time to come alive, the red-clothed female corpse, I don't know if it's the red-clothed serial murder case, let's go and have a look, where is Da Zhao?"
