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 at Liu Yongxin constantly.

He was initially reluctant to get the fourth level of the face restoration technique, but now he realized that the benefits of upgrading one aspect alone were unbelievable.

Because now this face restoration technology is no longer limited to whether it is a human face or not, but also the analysis technology of the portrait in surveillance or various very obscure image data.

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

In the vernacular, no matter how blurry the image is, I only need to find the data of the various positions of the facial features in the image, such as the facial features, and I can calculate the original shape of the facial features through these data.

Just on the phone, Zhou Ning said this idea, and also sent it to Dr. Lu to study the steps and directions in detail, Dr. Lu was so happy that he patted his chest and said that he was going to expand the development content of the software.

"Yes, the first phase of the design has been completed, and the debugging has been tested many times for a week, and the effect is very good, and the details such as the color of the iris can be adjusted later, but there is no suitable skull or bone fragments, so the software simulation can be recovered, and Dr. Lu means, let me follow the past to experiment for a while."

Liu Yongxin was stunned.

"It's time to go, it doesn't matter if I play two days in advance, it's just this bone fragment, do you have any requirements?"

Zhou Ning shook his head.

"There are no requirements, but it would be better if you knew the skull fragments of my appearance, so that you can make a corresponding comparison, of course, if the bones of the whole body are broken, this part of the skeleton computer analysis and restoration system, in the debugging stage, is the content of the second phase."

Liu Yongxin blinked and approached Zhou Ning.

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

"That's natural, they contacted a lot of experts and they all participated, but now there is a shortage of forensic professionals, because although there is a forensic specialty, these visiting professors will not participate in the research of software, and they are not suitable.

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

Liu Yongxin was stunned for a moment, this statement exceeded his expectations, raised his hand and pointed to his face, and kept shaking his head.

"Just me? I just studied a junior college on the job, but I have been boiling a little more over the years, and if I don't succeed in the past, I will be a burden to you. ”

Zhou Ning shook his head.

"Master, don't be modest, I think it's most appropriate for you to go, no one can compare with the experience, my tutor was highly educated, but those are all theoretical knowledge, what we need now is practical ability, you must know that without your persistence and matchmaking, this software would not have been possible."

Liu Yongxin blinked.

"Do you think I can do it?"

"There is no more suitable than you, in fact, in the R&D team, I initially intended to cooperate with the forensic office of the city bureau, but after contacting it, the forensic office of the city bureau is investigating a case for many years, and the one who can be sent is a forensic doctor who is about my age, Dr. Lu thinks 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 in the chair.

"I didn't expect that I could rely on my apprentice to be brilliant when I am old, since you and Dr. Lu both think that I can do it, I will not push back, I will do it."

Zhou Ning called Dr. Lu with a smile and said that Liu Yongxin agreed to the appointment, and Dr. Lu was very happy over there, and asked Liu Yongxin to wait patiently for their letter of appointment, and as for the treatment, the final result was given after the hospital's reaction.

Hanging up the phone, Zhou Ning saw Liu Yongxin coming to the computer, wearing reading glasses and seeming to be looking at something.

Zhou Ning leaned over and found that it was an email, a document issued by the forensic office of the Municipal Bureau, followed by a DNA test report, at this time Liu Yongxin had already seen the last page, and when he took off his glasses, Zhou Ning hurriedly asked:

"Master, what notice did the city 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 all these years, so you don't know much about Qindao, there is a Qindao red-clothed serial murder case, and in more than five years, there have been eleven consecutive crimes.

In this case on February 25 this year, a piece of rice green liquid was extracted from the deceased's body, so this DNA was sent out and asked by various districts and cities to help investigate. ”

Zhou Ning raised his eyes in surprise, eleven serial murder cases, it was still five years, this person was murderous enough.

"In this recent case, Mi Qing liquid was found? Didn't there be any other evidence left before? ”

Liu Yongxin shook his head.

"The dead are generally discarded in the garbage heap, the evidence is badly damaged, and the bodies are generally found in a state of high decay, and some have even been eaten by rats and wild dogs, leaving very little evidence.

Last year, the provincial department and the Ministry of Public Security both sent people to help with the investigation, but because of the lack of evidence chain, it was impossible to find more favorable information, and these cases generally occurred in the urban-rural junction around Qindao City, which perfectly avoided the monitoring set up by the city.

As for the fingerprints, some were found, but after searching, none of them were murderers, and most of these fingerprints were waste pickers or sanitation workers. ”

"What about the dead? Didn't the identity and fingerprints of the deceased be found? Do all 11 of these 11 have anything in common? ”

Liu Yongxin shook his head.

"The deceased were all fingerprinted, five of the eleven victims do not know their identities now, and four of the six female victims found out were high school students, day students, found that they did not go home, contacted the school, and found the body within three to five days after reporting the case.

There are also two night shift girls in the surrounding factories, if you want to say what they have in common, that is, they are very thin, and the time of disappearance is at night, and they are wearing red clothes, anyway, in order to catch this murderer over the years, the police force invested is innumerable, but there has been no news.

And the school is self-studying at night, parents are required to pick up and drop, and female students are not allowed to go home alone, starting from the end of 09, to the current five cases, the murderer is more secretive, and the place where the body is thrown is becoming more and more remote.

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

However, I suspect that these five victims may be street women, all of whom are shady professions, with a large population mobility, most of whom are not locals, and these people are killed, and it is not easy to be found, so this case is even more confusing. ”

Zhou Ning nodded, Liu Yongxin's suspicion is very strong, it is true that it is difficult for such people to conduct an investigation during the census, and the original family rarely asks, if it is really dead or missing, I am afraid that the family will not know.

Just thinking about it, Zhou Ning paused and raised his eyes to look at Liu Yongxin.

"Master, are all the bodies of these people preserved?"

Liu Yongxin was stunned and nodded slowly.

"High decaying corpses, cryopreservation doesn't make much sense, but the bones have been processed and preserved, why do you ask this? Wait a minute...... You mean, this software needs to do a lot of experimental data, and you want to use the software to restore their appearance, and then conduct an investigation? ”

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

"Don't think about this, there are more people handling this case, and it has also alarmed those people in the provincial department, the Ministry of Public Security, and the municipal bureau who will not agree to participate in your software trial."

Zhou Ning was stunned, and he couldn't react for a while, if the skull is restored, isn't it good for the investigation of the case, why do you oppose it, you should fully support it.

Liu Yongxin sighed, and then said:

"Your kindness, I understand and I understand, but you must 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, although they all think it is a good thing, but many people have a pimple in their hearts, understand?"

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

"Okay, then forget it, but after that, I'll beat the side drum with Dr. Lu, and if he thinks it's feasible, then go and discuss it with the city bureau, and we won't participate."

Liu Yongxin smiled.

"Well, this is okay, but don't look for it right away, okay, go and type on your keyboard, I see you have written a lot of pages, it seems to be a story, and there are these cases we are dealing with, are you going to send a novel?"

Zhou Ning was a little embarrassed.

"I'm just looking for a way to vent my bad emotions, you don't mean to learn to explain it yourself, I think this method is very suitable for me, but I haven't thought about whether to publish it yet, Master, don't tell anyone else!"

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

Zhou Ning scratched his head.

"Xu Da said last time that he would invite us to a buffet, but he hasn't fulfilled it yet, I learned from him, and when you receive the letter of appointment, I'll invite you to have a good meal, right?"

As soon as the words fell, 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 did Zhou Xiaozhou say bad things about me?"

Zhou Ning was startled and hurriedly jumped off the table.

"Xu Da, why are you here?"

Xu Dayuan looked like a lawsuit, and his eyebrows were about to be twisted together.

"Bad news, it's coming to life, the corpse of the woman in red, I don't know if it's the serial murder case in red, let's go and see, what about Da Zhao?"
