Chapter 284: Scattering Flowers

Jiang Yuan followed the "Duck Group" members to watch the video for a while, which could be considered familiarizing himself with the new surveillance system.

It must be said that watching videos with a few men, and watching sports videos dominated by men, and without a ball, the rest is pure boredom.

Zhuang Wei operated the software, tracking the whereabouts of a criminal suspect, from the core area of the county to the point where he got into a car. The whole process... Jiang Yuan found it super boring.

It must be said that as he did more and more cases, cases that were too conventional consumed a lot of willpower.

As Jiang Yuan watched, he couldn't help but take out his phone and look at it.

It had been a long time since he looked, and many groups had already brushed out hundreds of messages.

The "Shannan Fingerprint Exchange Group" also had a red 【@】 symbol.

Jiang Yuan clicked inside and saw that the one who @ him was actually Li Li Zemin.

As a comrade-in-arms who fought together in the province-wide fingerprint battle, Li Li Zemin could be called a clear stream among provincial experts.

He and Jiang Yuan smoked Soft Zhonghua together, shuttled through major cases selected by the province together, and killed together, from the first day to the fifteenth day, without stopping their calls.

Jiang Yuan clicked on the "Shannan Fingerprint Exchange Group" with emotion.

Shannan Li ****** Yuan. Help me look at this fingerprint. A silly kid took this fingerprint from the velvet cloth of the trunk. Highly suspect it's a repeat offender.】

Changyang City—Shuidong District—Trace Inspection He He Guohua: 【My Brother Jiang is too busy. In the last two months, he has continuously solved five or six homicide cold cases, and he can compare fingerprints in between.】

Shannan Li Li Zemin: 【I always pay back ten for one. Please, Jiang Yuan, handle a fingerprint, and I'll do ten miscellaneous jobs for him later.】

Changyang City—Shuidong District—Trace Inspection He He Guohua: 【Brother Li, you're bragging.】

Shannan Li Li Zemin: 【Not at all, I'm keeping count. Just like the Soft Zhonghua cigarettes I smoked from Jiang Yuan back then, I wrote down how many there were. If I can't pay it back, I'll have my son pay it back.】

Shannan Zhu Zhu Huanguang: 【@Changyang City—Shuidong District—Trace Inspection He He Guohua, you must be a cycle older than Jiang Yuan, is it okay to call him brother?】

Changyang City—Shuidong District—Trace Inspection He He Guohua: 【Brother Zhu, your criticism is correct. I can't mess up the seniority just because I'm in the group. In Changyang City, we all call him Jiang Ye now. Jiang Ye, I'm sorry, I won't @ you.】

Provincial Department—Fingerprint Post—Yang Ling: 【Call him Jiang Shen. If the public security hears "Jiang Ye," it's easy to be hit.】

Jiang Yuan looked at the hundred or so messages with satisfaction, and only after they started changing topics did he forward the fingerprint sent by Li Li Zemin to himself.

Some things, if they are too hard to get, it is difficult to enjoy the glory and happiness they bring.

Conversely, if they are obtained easily, the sense of happiness in the heart is even stronger.

It's like a relocated household, it's like a second-generation relocated household.

It's like Jiang Yuan.

"Brother Zhuang, give me a computer to use. The kind with better performance." Jiang Yuan held the fingerprint, feeling that the Image Office was very suitable for the needs of processing fingerprints.

There was also a need for image processing here, and the newly equipped computers were all top-of-the-line from two years ago.

Zhuang Wei immediately gave one to Jiang Yuan, entered the login password, and smiled: "The password is the police number."

"Good. Many thanks." Jiang Yuan was not surprised at all. It is too common for police officers to use their police numbers as passwords. Many police officers only broke this bad habit after their wives checked their phones.

For simple, incomplete fingerprints, there is no need for any special software. Jiang Yuan put it in and started processing it with Photoshop.

Of course, Photoshop actually has nothing to do with "simple." If this thing is used well, any photo can be processed.

The so-called PS originally referred to using Photoshop to process. However, photos that might have required experts to deal with in the past were later "fool-proofed" by various software, so that those who didn't understand technology and didn't have money could also PS a bunch of beautiful photos.

However, the functionality of Photoshop has never diminished. In fields beyond just processing fat, thin, black, and white faces, its application range is still wide, but many people are not good at using it.

Too many and too powerful functions are not something most image processors can do, and the difficulty has increased, so many people will choose some software that plagiarizes Photoshop's functions as a substitute. In addition, the price of genuine Photoshop is also one of the problems.

"I'm processing a fingerprint, a friend happens to need it." Jiang Yuan explained to Zhuang Wei and started operating on the computer.

Zhuang Wei watched with sorrow.

Just like what he saw before, when Jiang Yuan did image enhancement, it was very difficult for him to understand. This kind of—wait, Zhuang Wei suddenly found that he seemed to understand Jiang Yuan's operation a little.

In fact, the enhancement of fingerprint images was originally simpler than the enhancement of video images.

This is not just a question of image complexity, but also a question of familiarity.

Zhuang Wei is also a police officer who has been doing it for more than ten years. He has seen thousands of fingerprints. For a fingerprint, he has a very clear and rich experience in his mind about what it should look like.

Therefore, watching Jiang Yuan do image enhancement, he might not have a direct feeling, but watching Jiang Yuan do fingerprints, he suddenly understood Jiang Yuan's direction and goal.

Knowing where the destination is, and then looking at the process, the room for operation here is easy to understand.

What's more, Jiang Yuan didn't use any particularly complex means.

He just needed to process this fingerprint to be a bit cleaner.

Even, he didn't need to process the whole fingerprint, just make a part of it beautiful and clear, and that would be enough.

With his Level 3 + Level 4 fingerprint analysis method, even if there is only one-third of the basic clear fingerprint, Jiang Yuan can get enough information—provided that the compared fingerprint is very complete and clear. And this time, the target fingerprint is a repeat offender, so there is no need to worry too much about this.

Therefore, super-strong fingerprint analysis and super-strong image enhancement complement each other.

Anyone who has used Photoshop knows that the software's processing of images often involves sacrifices. If you only process a small part of the image, the difficulty will be reduced.

As a result, Jiang Yuan found it easier to get a small piece of very clear fingerprint.

And continuous, complete fingerprints actually have more advantages in fingerprint comparison.

Zhuang Wei easily saw Jiang Yuan's strategy. At this time, looking at Jiang Yuan doing image enhancement again, he slowly watched it.

To say the least, Zhuang Wei's foundation is not bad. He studied related majors in university more than ten years ago. Moreover, as everyone knows, knowledge involving digital image processing, such as Fourier transform and discrete functions, has not changed much in the past ten years.

In other words, as long as a person is diligent and eager to learn, and works hard to make progress, even if they are a bit stupid, as long as they can read discrete functions and play with power transformation, and relatively skillfully master piecewise linear transformation functions, then even if they have to spend several times more time than others to learn mathematics, they will not be easily eliminated by society.

Just like Zhuang Wei, the time he really used to learn in these ten years is not much, but this is mainly because he lost the environment for learning.

Most people are like this. After starting work, they start endless output, because of pressure, because of responsibility, because of desire...

When everything is judged by quantity, 3,000, 6,000, 9,000, or all only have meaning in the present.

Jiang Yuan opened a road for Zhuang Wei.

During the time Jiang Yuan was doing image enhancement, Zhuang Wei's mind suddenly recalled a lot of knowledge he felt he had forgotten. He even started to feel that being a squadron leader of the Video Investigation Squadron was meaningless.

Even if it is the brigade leader of the Video Investigation Brigade—of course, if it can really be achieved, as the first-generation four-eyes old duck, he is still duty-bound.

"Almost there." Jiang Yuan stopped.

Zhuang Wei's mind was also cleared: "Ah, done?"

"En, I'll compare the fingerprints, maybe I still need to correct it, but it's basically like this." Jiang Yuan actually knew that Zhuang Wei was learning on the sly, and he didn't care, and incidentally introduced two sentences to Zhuang Wei.

Some things, if you can learn them, you don't need to steal them; if you can't learn them, you can't pour them in.

The finished fingerprint map was thrown into the software, and only marked once for feature points, and the same fingerprint was found in the 8th place.

This is a very forward ranking. Just as Li Li Zemin said, the fingerprint is indeed that of a repeat offender.

It must be said that the judicial system of Shannan Province is really doing a good job in fingerprinting.

Jiang Yuan clicked submit and took out his phone. Zhuang Wei was a bit dazed and asked: "Matched?"

"Right."

"Um... homicide case?"

"Shouldn't be, I didn't ask about the case details specifically. I'll tell Brother Li." Jiang Yuan said and dialed Li Li Zemin.

Li Li Zemin answered almost in seconds.

In the earpiece, Li Li Zemin's magnified laughter came out: "Hahahaha, I knew it, Jiang Yuan, you doing fingerprints is a matter of minutes. Matched?"

"Matched, but it took almost two hours." Jiang Yuan smiled: "We have to be accurate about the time, otherwise, you'll say I was negligent."

"How is that possible? From the first time you handed me a cigarette, a Soft Zhonghua, I knew I had made this brother."

"If you have time to come on a business trip, I'll treat you to cigars."

"Good fellow, you wait... oh, I see the fingerprint you submitted in the background. The expert review is not finished yet. Forget it, I'll go notify them to catch the person."

Although Jiang Yuan is also a fingerprint expert certified by the Provincial Department and can do expert review. But the fingerprints he made himself still need to be reviewed by others.

The domestic requirements for the accuracy of fingerprint evidence are still very high.

Jiang Yuan responded and asked: "What kind of case is it?"

"It must be a homicide case. Would I be embarrassed to ask you for a small case? But it's a current case. Looking at the scene, it should be a repeat offender, the crime has escalated..."

Li Li Zemin said a few words simply and hung up the phone in a hurry to report the situation.

Jiang Yuan put down the phone and smiled at Zhuang Wei, who obviously heard it: "I really didn't expect it to be a homicide case."

"That's what I said." Zhuang Wei's smile carried a trace of helplessness: "Who could have expected that a fingerprint that even a fingerprint expert couldn't make, and had to ask someone to compare, would be a homicide case."

Hum.

Jiang Yuan's phone lit up.

"Shannan Fingerprint Exchange Group" flashed red again:

Shannan Li Li Zemin: 【Thanks to my brother Jiang Yuan for matching a homicide fingerprint for our city, scattering flowers!】

Changyang City—Shuidong District—Trace Inspection He He Guohua: 【Jiang Shen, yyds, scattering flowers!】

Shannan Zhu Zhu Huanguang: 【Review passed. Scattering flowers】

Provincial Department—Fingerprint Post—Yang Ling: 【Ningtai Jiang Yuan, Fierce Flames Towering.】 ===== CHAPTER 285 =====

Provincial Department—Fingerprint Station—Yang Ling: 【Jiang Yuan of Ningtai, his murderous aura is surging.】
