civil forensic

Chapter 123
"It's been so long?"

Wu Jun sat by the window in the office, smoking Zhonghua leisurely, beside him was a pot of Chlorophytum, with three or four filters inserted in it.

To be honest, a week ago, Wu Jun was not in such a relaxed mood to smoke.

It is really tiring to do forensic work in a county alone.

Jiang Yuan put the rest of the red eggs on the table, and said, "Go to the video office and see them making images, and I helped."

"The video work is also very troublesome." Wu Jun described it to show that he knew it, and then passed a cigarette to Jiang Yuan, saying: "Slow down, don't be so anxious, we work in the county, we don't want money, If you don’t have a picture name, what you can have, isn’t it just a slower pace of life and a little more normal life?”

Jiang Yuan listened to the life of normal people, looked at Wu Jun a little funny, and said: "We are all forensic doctors, so we can't live a normal life."

"About this..." Wu Jun looked around vigilantly, got up and closed the door again, then took out his Guan Yu portrait from the drawer, hung it on the door, lit incense, took a moment to inhale a Chinese, and said slowly: "In my life, I have a clear conscience anyway. I am afraid of what I should be afraid of, and I should worship what I should worship. I don't know about your generation."

Wu Jun took Jiang Yuan to the front of Guan Yu's statue.Jiang Yuan had no choice but to follow suit.

"Well, you have seen enough dead people this time. In the future, if you encounter ten or eight dead people, you will pay your respects to Guan Yu." Wu Jun pondered for a while, decided to determine a number, and said, "When you encounter dead people 8, just worship, let's play it safe."

Jiang Yuan couldn't help laughing: "Where can we find a case where 8 people died now?"

"Didn't you meet?" Wu Jun said: "There are a lot of perverts, look for them carefully, there will always be some. Like this case, if Li Sanqiu hadn't just met a donkey friend, he would be discovered next time. When and what will it look like?"

Jiang Yuan had no choice but to pay homage to Guan Yu again, and said, "Okay, let's put it away so that no one will see it."

"You can see it when you see it." Wu Jun said that he put it away carefully, and continued: "20 years ago, there were still many murder cases, such as the famous case in the central part. The murderer wanted to take revenge on the society, and then He made his own guns, killed people randomly, and later stole standard weapons and killed many people."

"Anti-social personality?"

"Maybe. However, what this guy did back then may not be impossible for people to do now. He made his own firearms in the machine tool factory, but the gunpowder used a relative's shotgun certificate..." Wu Jun started talking in a daze .

Jiang Yuan just made a cup of tea and listened, then read the newspaper for a while, it's time to get off work!
……

the next day.

The Sun Also Rises.

Work proceeds normally.

Jiang Yuan also appeared in the office normally.

Wei Zhenguo unexpectedly appeared in the office.

"You did it." Wei Zhenguo and Jiang Yuan knew each other too well, so they asked directly when they met.

What he held in his hand was the portrait of the suspect printed yesterday.A middle-aged man wearing a hat, standing under a big tree, looking up at the sky with a silly look was captured by the camera.

Jiang Yuan glanced at it, nodded and said, "I made it for the imaging office yesterday, and it's in your hands?"

"Yes, our sixth team used to do a lot of theft and burglary. When I came back, the captain let me take a few days off, so I took this case." Wei Zhenguo explained casually.

"Is Mu Zhiyang okay?" Jiang Yuan came back earlier than Wei Zhenguo.

Wei Zhenguo nodded, and said: "There is no problem with the function of the arm, but it needs to be cultivated for a few days. Wen Ming will send him back later, and it will be almost enough to stay in our Ningtai hospital for a few more days."

"There won't be any sequelae, will it?"

"No." Wei Zhenguo said, looked at Wu Jun again, and said, "Then if you are free, why don't we finish this case together?"

Jiang Yuan's guilt faded quickly, and he asked curiously: "Isn't this done?"

"For the video, it's finished. For us, it's not just the beginning." Wei Zhenguo smiled bitterly: "The most important thing is to have solid evidence. It's best to have a video or photo of him committing the crime. The second is to prove the time of the crime. Duan, he did appear around. The third is to see if he can find places and photos of his abandoned appendages to prove that he did touch the stolen goods, so that it can be regarded as a nearly complete case."

Jiang Yuan said "Oh" and asked, "If I didn't help you find it, how would you solve this case?"

"Either you don't break it, or you just catch the evidence of a case and try to find a way to dig deeper. If you really want to break it, then go to the scene and wait for them to commit crimes, and catch a current one." After Wei Zhenguo said a few plans easily , said: "Mainly I want to catch a big one."

"big?"

"Thiefs, the news spreads quickly. If we use video methods to capture the old volume, the suspect will be arrested and sentenced. These guys will pay special attention to the cameras. The cameras in key positions may destroyed."

"You can be caught if you destroy the camera."

"I don't want to spend three or two months on such a case." Wei Zhenguo is now a person who has done big things, and looking at the petty theft in the county, he obviously looks down on it.

Jiang Yuan then looked at Wei Zhenguo, waiting for him to continue.

Wei Zhenguo organized the language, and said: "There are only five traditional pickpockets left in the county, and one of them hasn't come out yet. What I mean is, can the five pickpockets be captured by video? All the evidence was fixed, I went back and caught it again, and the market will be quiet in the future.”

Wu Jun was a little curious at this time: "There are really only 5 people left? You know this, and they haven't been arrested yet?"

"I'm not all busy recently." Wei Zhenguo said, and then said: "Actually, they are all habitual thieves. Don't look at them all in their 50s and [-]s. They are not skilled and courageous. Some of them even went to Beijing, Shanghai and Guangzhou. , I can’t go on, and I can only come back. I don’t know anything, I just think about how to steal things all day long. I can’t steal anything.”

Jiang Yuan knew a little about these middle-aged crisis thieves yesterday. It was a little funny, but he didn't feel any sympathy. He thought about it: "Why don't you just copy the files to me? If you watch a lot of videos, you may have to a little time."

"Okay, I'll go get it." Wei Zhenguo responded and ran away.

After a while, he ran back with the four-eyed boy of the first, second and third generations.

This is because I heard that Jiang Yuan is going to make images, so they all come to see them.

"Where do we start?" Gao Jiansheng, a boy of three generations and four eyes, was more active than Jiang Yuan.

"It's better to find out if there are any ready-made photographs of the crime process. If so, make the portraits clearer and determine who is who." Wei Zhenguo also asked Jiang Yuan.

"Then look for it first." Jiang Yuan didn't hesitate, opened the video and searched.

Gao Jiansheng moved closer to Jiang Yuan and stared at him without blinking, as if he wanted to learn the secret.

Yesterday, Jiang Yuan did the image enhancement, but he still hadn't realized it. He saw Wei Zhenguo today, and recalling Jiang Yuan's operation yesterday, his feeling was completely different.

Gao Jiansheng, who is a boy of three generations and four eyes, is relatively young. He has not been in the county bureau for a long time, and he still has fantasies about technology. In this regard, he is somewhat similar to Wang Zhong.

However, Jiang Yuan is not optimistic about Gao Jiansheng's ability to learn image enhancement technology well.The gold content of this thing is much higher than the fingerprint comparison.

Fingerprint comparison is very talented, but it also has a high ceiling for hard work and ability to make up for one's weakness. If you work hard, and someone reminds you, you can perform normally up to LV2 level, have a little bit of talent in a certain area, or be particularly able to endure hardships, etc. There is also a chance to LV3.

But the technology of image detection is not like this.In the final analysis, what Tuzhen plays is mathematics, then physics, and then there may be requirements for computer technology such as algorithms.

Therefore, if there is no strong basic theoretical ability, ordinary people will be LV1 exhausted, and they will not even be able to touch the door of LV2.

Although it is said that starting to learn mathematics at the age of 30 can achieve small success, but normal people work, and there are a few who can work hard to start learning mathematics at the age of 30.

Based on this, Jiang Yuan sat in front of the computer and played the video by himself, without any intention of explaining.

But because he didn't explain, Gao Jiansheng was quite happy watching it.

We all know that words like Fourier can cause depression.

If you don't say it, you don't necessarily think about it.

Jiang Yuan set up six screens to watch at the same time, and then stared at the three screens with Wei Zhenguo respectively. After a while, he caught a pickpocket who was stealing from the camera at the bus station.

As soon as Jiang Yuan pressed a few shortcut keys, all the videos of his crimes were intercepted.

In the video at this time, the thief's face could not be clearly seen. Jiang Yuan still processed the entire video as before, and then extracted a dozen frames separately for high-definition processing.

This set has ready-made routines and ready-made software to operate.In Gao Jiansheng's view, Jiang Yuan just pressed a bunch of shortcut keys, just like yesterday.

This made Gao Jiansheng quite happy.

The expressions of the first-generation four-eyed boy and the second-generation four-eyed boy are also very exciting.

This routine also looks quite complicated, but it is not impossible to learn.

If you learn this set of techniques, it will be too easy to cut a high-definition picture from the video in the future to catch a thief or something.

Jiang Yuan saw the expressions of the three of them and pretended not to know.

In fact, his set of operations is not fixed, and the three of them should be able to see it when they continue to make other videos after a while.

This kind of thing is actually like making software for hackers.

Normal hackers also use software to do their daily work, and no one really knocks out a software to use it.But when it comes to technical depth, things inside are much more complicated.

What Jiang Yuan is doing now is actually mainly for portraits.For example, the high-definition of the blurred license plate most commonly used in criminal investigation is another model.

Of course, it is better to be able to master a few tricks than to have no tricks at all.

Jiang Yuan didn't say anything anyway, and continued to work, poaching thieves.

After a while, Jiang Yuan helped Wei Zhenguo fix the criminal evidence of the three thieves.

Wei Zhenguo was still smiling all over his face at first, but gradually, his expression became sad.

"What is Lao Wei thinking?" Wu Jun asked curiously.

Wei Zhenguo sighed: "In fact, I have been catching thieves for half my life, especially this kind of pickpocket. In the past, I even organized a plainclothes team to catch people. Now, pickpockets can't be hungry anymore, and those who can change careers have changed careers. The remaining 5 stupid thieves were caught this time, and there will be no live pickpockets in the Ningtai market in the future."

Jiang Yuan happened to be the fourth one and asked, "Then leave a seed for you?"

"No need." Wei Zhenguo quickly apologized: "I'll just make a fool of myself and catch it. If I want to pickpocket in the future, I'll just go to Qinghe to see it."
