Chapter 39: Keeping the Secret
Zhou Ning smiled.
"Master, I'm a newcomer. I've only been here for a few months. You're even more arrogant than Huang Shiren. You know why Dr. Lu is urging me to do this, but I have too little experience. Although I have some ideas, I'm not good at the technical issues involved. I need to think about it carefully."
Liu Yongxin rolled his eyes at Zhou Ning.
"You're keeping me in suspense, right? Tell me what direction you're looking at?"
Zhou Ning had no choice but to say something today. Liu Yongxin would not let him go. He also hoped to get out of this case as soon as possible. He was very touched by this kindness.
But when it comes to typing away on the keyboard, Zhou Ning feels a little embarrassed. That was just a way to pass the time when he was bored. After all, that's how the authors he likes update their works, and the cases he has experienced are even more thrilling.
"No secret, but I would like to find a software developer to help me."
Liu Yongxin sat directly opposite Zhou Ning, holding up a teacup and motioning Zhou Ning to continue. His persistence made Zhou Ning laugh.
However, there is a paper on the portrait restoration technology, which was published in 2021. The fifth generation of the "Jingxing CCK Portrait Simulation Combination System" was developed at the China Criminal Police College .
The "Jingxing CCK-IV" can spell out 9.9 billion facial images, which can almost be called "infinite".
In other words, theoretically, there are 9.9 billion suspect facial images in the image library, and we can use the descriptions of witnesses to "match" and find the face that is closest to the suspect.
This software is simply amazing. It has been involved in many important archaeological and major case investigations. It is also known as the world's first software, and it has already reached the ceiling level.
However, this is based on the direct combination of eyewitness descriptions, which can be considered a branch of portrait restoration technology.
Since others have made such in-depth progress in this direction, Zhou Ning did not want to develop in this direction. If he could bring the skull restoration to the top level, it would be a new breakthrough, and it would be more in line with his job.
Thinking of this, Zhou Ning slowly said:
“Two days ago, I worked with Teacher Xia to restore the model of the deceased. I have some ideas about how to fill the human skull according to different settings such as age, gender, genes, hair color, skin color, weight, and health status.
In this way, there is no need to carry out restoration like sculpture, which takes more than ten hours to produce a plaster model. If you are lucky, it's okay, but if you are unlucky or the person operating it is different, the technology will be difficult to control and the restoration will be meaningless.
Therefore, if we work with professional software designers, collect a lot of data, input it, and combine it with X-ray and CT scanning technology, we can synthesize it in the system. For example, if we have a broken skull, the software can automatically piece it together.
Of course, when it comes to professional software, professionals must be involved to materialize the professional knowledge into the software. For example, for bone injury, bone strength must be designed, so many parameters are required.
For example, the bone density of people of different ages, mechanical parameters, the direction of penetration of blunt and sharp objects, and countless other parameters are not realistic if they are entered one by one. This requires artificial intelligence, which is to let AI automatically calculate and learn..."
The more Liu Yongxin listened, the more surprised he became. Of course, he obviously didn't understand what was said later, but this did not affect his excitement. In the end, he stood up and spilled the tea in his hand without even realizing it.
Pointing to the big belly monitor on the table, he said tremblingly:
"Just use a computer, operate this kind of software, input only X-rays and CT scans, and you can synthesize a portrait?"
Zhou Ning nodded and pushed up his glasses.
“Well, you can understand it this way. Although I am a little idealistic, as long as the amount of data is large enough, and the software is added with relevant data such as car accidents, drownings, stabbings, slashes, gunshot wounds, etc., it can be inferred how much force the deceased used and the corresponding damage caused.
Or, it can be used to determine whether the suspect's confession is true. According to them, in a specific environment, the scene can be simulated and reconstructed to determine the accuracy of the testimony.
For example, if the victim was hit by a hammer from behind, the murderer's weight, height, strength, and behavior habits can be more accurately estimated, and it is possible to simulate an animation. Of course, this is just what I can think of at the moment, but there are many professions involved."
Liu Yongxin's nostrils flared continuously. If the software Zhou Ning mentioned could really be developed, the appearance of a deceased person with disfigured face could be reconstructed in minutes. How much time could be saved in searching?
Just like the 12.10 case, if Zhou Ning had not asked Teacher Xia to make a facial model of the deceased, the identity of the deceased would have been difficult to ascertain. If the identity of the deceased had not been found, no clues would have been found in the social investigation, and the case would have remained unsolved. Although Yu Jingwei and Wang Yi would also be suspected, the difficulty of solving the case would have increased greatly.
"Have you talked to that Dr. Lu?"
Zhou Ning shook his head.
"No, he's a PhD in chemistry, and this has nothing to do with his research direction. There's no point in talking about it."
Liu Yongxin waved his hand.
"That's not what I meant. The last time Dr. Lu came, I felt he was very sincere. He also said that if your future research direction has nothing to do with chemistry, he can help you contact relevant people and equipment. I think we can have a chat.
After all, this is a good thing, adding luster to it. If we cooperate with Qindao University, then the nature of this will be different. This will represent our Qindao, and even Ludong Province or China. Just like the last paper, you wait for me to ask for you. "
The more he talked, the more excited Liu Yongxin became. Finally, he took out his cell phone and made a call.
"Hello, Dr. Lu. I'm Liu Yongxin from the Forensic Medicine Office of the Criminal Police Brigade of the Qidong Branch."
"Hello, Forensic Doctor Liu, is there any news from Forensic Doctor Zhou?"
Liu Yongxin glanced at Zhou Ning.
"Our case was very difficult. We worked on it for three or four days and it has just come to an end. He hadn't slept for a few days. He and his girlfriend worked together to study the skull reconstruction of the deceased. This helped us solve the case in time."
Dr. Lu seemed very interested.
"It's so magical that a person's face can be restored using a skull?"
Liu Yongxin had whetted Zhou Ning's appetite so he talked about the case in a casual way and also talked about Zhou Ning's next idea. Of course, he was just chatting with his master, but he just had this intention. After all, it needed a professional to control it. It was not something that could be done casually.
As soon as he finished speaking, Dr. Lu couldn't sit still anymore.
"Liu, tell Zhou to stop worrying and give me two days. I will discuss this with the hospital leaders. This software design is not just a design, it is also a unique research direction. I will do my best to facilitate the implementation of this software research project.
However, this software involves a lot of disciplines and professional talents, including medicine, computer science, software development, electronic information, communications, software engineering and computer, and even criminal investigation.
I will see how to form a team. After all, if this is successful, it will also add luster to Qindao University and will be more conducive to Qindao University's enrollment."
Liu Yongxin smiled and raised his eyebrows at Zhou Ning.
"Okay, then you discuss it first. I'll keep Zhou Ning calm and ask him to sort out his ideas and send them to you later."
Dr. Lu was very grateful and thanked me repeatedly before hanging up the phone.
Zhou Ning held back his laughter. Liu Yongxin and Xu Dayuan, like each other, took great care of him. It was not because they were his second uncles. Both of them were sincere in supporting the younger generation and wanted to give him a hand because they felt that he was making progress.
"Thank you, Master. I'll sort it out later. In fact, software can be developed in stages. For example, in terms of facial restoration, this can be the first phase. Then, each time a new function is developed, we just need to continuously upgrade the software."
Liu Yongxin waved his hand.
"I don't understand these things. Anyway, it's right to find a professional to help. Dr. Lu will definitely do his best. Don't worry, we'll just count on our fingers and wait. He will come within two days, and maybe he will bring others with him."
Zhou Ning was stunned and thought for a long time but couldn't figure out who Liu Yongxin was talking about.
“Who will Dr. Lu bring?”
