novice forensic medicine

Chapter 39

Zhou Ning smiled.

"Master, I am a newcomer. I have just joined the job for a few months. You are more Huang Shiren than Huang Shiren. You know why Dr. Lu urged me, but I have too little experience. Although I have ideas, the technical issues involved I'm not good at it, and I still need to think about it."

Liu Yongxin gave Zhou Ning a blank look.

"Tell me about it, tell me what direction you're looking at?"

Zhou Ning couldn't resist, if he didn't say something today, Liu Yongxin would not let it go, and he also hoped that he could get out of this case quickly, and he was very moved by this intention.

But Zhou Ning was a little embarrassed when he said that he was typing on the keyboard. It was nothing more than a leisurely resolution. After all, the update of the author he liked was like that, and the cases he experienced were even more thrilling.

"No secret, but I would like to find a software developer to help."

Liu Yongxin sat directly opposite Zhou Ning, holding a teacup as a gesture to Zhou Ning, and continued, Zhou Ning couldn't help but laugh at this persistence.

However, there is a paper in the portrait restoration technology, which was published in 2021. The fifth generation of the "Police Star CCK Portrait Simulation Combination System" was developed at the Huaguo Criminal Police Academy.

Police Star CCK-IV" can spell out 99 billion faces, which can almost be called "infinity".

That is to say, in theory, there are 99 billion suspect faces in the image library, which can be "checked in" based on the descriptions of witnesses to find the face that is closest to the suspect.

This software is simply heaven-defying. It has also participated in the detection of many important archaeological and extraordinarily serious cases, and it has the title of the first case in the world. It is already a ceiling-level existence.

However, this is based on the descriptions of eyewitnesses and combined directly. This is a branch of portrait restoration technology.

Since people have made such a deep effort in this direction, Zhou Ning didn't want to develop in this direction. If the skull restoration part can be brought to the top level, it is already a new breakthrough, and this is more suitable for his own work. combine.

Thinking of this, Zhou Ning said slowly:

"Two days ago, I didn't restore the model of the deceased with Teacher Xia. I had some experience. If we can fill the human skull according to different settings such as age, gender, gene, hair color, skin color, weight, and health status.

In this way, there is no need to perform sculpture-like restoration, toss for more than ten hours, and just make a plaster model. If you are lucky or unlucky or the operator is different, then the technology will be difficult to control, and this restoration will also be difficult. It doesn't make sense.

Therefore, if a professional software designer cooperates, a large amount of data is collected and input, combined with X-ray and CT scanning technology, it can be synthesized in the system, such as a broken skull, this software can automatically stitch it together.

Of course, when it comes to professional software, professional people must be involved, and professional knowledge should be embodied in the software. For bone damage, bone strength needs to be designed, so there must be many parameters.

For example, the bone density of people of all ages also has mechanical parameters, the direction of blunt and sharp instrument penetration, and countless parameters. It is unrealistic to enter them one by one. This requires artificial intelligence, which is to let AI automatically calculate. "automatically learn"

The more Liu Yongxin listened, the more surprised he became. Of course, he obviously didn't understand what followed, but this didn't affect his excitement. In the end, he stood up directly, without knowing that the tea in his hand was spilled.

Pointing to the big belly monitor on the table, he said tremblingly:

"Just use a computer to manipulate such software, and only input X-ray and CT scan images to synthesize a portrait?"

Zhou Ning nodded and pushed his glasses.

"Well, it can be understood in this way. Although I think it is somewhat idealistic, as long as the amount of data is large enough, relevant data such as car accidents, drowning, stabbing, chopping, gunshot wounds, etc. are added to the software, so that it can be deduced How much strength, the corresponding damage caused.

Or, it is used to judge whether the suspect's confession is true. According to what they said, in a specific environment, the restoration scene can be simulated and reconstructed to judge the accuracy of the testimony.

For example, if the deceased was hit by a murderer in the back, the inference of the murderer's weight, height, strength, and behavior habits will also be more accurate. It is also possible to simulate animation. Of course, this is just what I think of at present, but what is involved A lot of professionalism. "

Liu Yongxin's nose kept flapping. If the software that Zhou Ning mentioned can really be produced, it can rebuild the appearance of such a dead person whose face has been destroyed in minutes. How much time can be shortened for searching?
Just like this 12.10 case, if Zhou Ning hadn’t asked Mr. Xia to make a facial model of the deceased, it would have been difficult to ascertain the identity of the deceased, and the identity of the deceased would not have been found, and clues would not have been found in the social investigation, then this case would have become an unsolved case. Although Yu Jingwei and Wang Yi will also be suspicious, the detection will increase the difficulty.

"Did you talk to that Dr. Lu?"

Zhou Ning shook his head.

"No, he has a Ph.D. in chemistry. These have nothing to do with his research direction, and it's useless to say."

Liu Yongxin waved his hand.

"That's not what I said. The last time Dr. Lu came, I think he was very sincere. Didn't he also express his opinion? If the future research direction has nothing to do with their chemistry, he can also help you contact the relevant people and equipment. I think we can talk.

After all, this is a good thing, and it adds luster. If we cooperate with Qindao University, the nature of this will be different. This will represent our Qindao, or even Ludong Province or Huaguo, just like the last paper Same, you wait for me to help you ask. "

The more he talked, the more excited Liu Yongxin became. Finally, he took out his mobile phone and dialed the number.

"Hello, Dr. Lu, I am Liu Yongxin from the Forensic Medicine Office of the Criminal Police Brigade of the Qidong Sub-bureau."

"Liu Fayi, hello, hello, is there any news from Zhou Fayi?"

Liu Yongxin glanced at Zhou Ning.

"Our case is very difficult. After three or four days of tossing, it has just come to an end. He hasn't slept for a few days. He didn't study the restored statue of the skull with his little girlfriend. This made the case solved in time. .”

Dr. Lu seemed very interested.

"It's so miraculous that a human face can be restored with a skull?"

Liu Yongxin had a good appetite, and he talked about the case and Zhou Ning's next step. Of course, he was chatting with his master, but he had this intention. After all, he needed professional people to handle Come on, it's not about the upper lip touching the lower lip.

As soon as he finished speaking, Dr. Lu couldn't sit still.

"Liu Fayi, please tell Zhou Fayi not to worry, give me two days, I will discuss with the hospital leadership, this software design is not only a design, but also a unique research direction, I will do my best to promote this software research The landing of the project.

However, there are many disciplines and professionals involved in this software, such as medicine, computer science, software development, electronic information, communication, software engineering and computer science, and even criminal investigation.

Let me see how to form a team. After all, if this thing is done, it will also add color to Qindao University, and it will be more conducive to the enrollment of Qindao University. "

Liu Yongxin smiled and raised his eyebrows towards Zhou Ning.

"Okay, then you discuss it first. I will hold Zhou Ning here and let him sort out his thoughts and send them to you later."

Dr. Lu was very grateful and thanked repeatedly before hanging up the phone.

Zhou Ning suppressed a smile, Liu Yongxin, like Xu Dayuan, took good care of him, not because of his second uncle's relationship, these two people sincerely support the younger generation, feel that they are motivated, and want to help even more.

"Thank you, Master. I'll sort it out later. In fact, the software can be developed in stages. For example, in terms of facial restoration, this can be used as a phase. Then every time a new function is developed, you only need to continuously upgrade the software."

Liu Yongxin waved his hand.

"I don't understand these things. Anyway, it's right to seek professional help. Besides, Dr. Lu will definitely do his best. Don't worry, we will wait with our fingers. He will come within two days, and he may bring others with him." Come."

Zhou Ning was taken aback, and after thinking for a long time, he couldn't figure out who Liu Yongxin was talking about.

"Who will Dr. Lu bring?"
