Chapter 293 Spreading Flowers

Jiang Yuan watched the video with the members of the Duck Team for a while and became familiar with the new surveillance system.

I have to say that watching videos with a few men, and watching sports videos that are mainly men, and there is no ball, the rest is pure boredom.

Zhuang Wei operated the software to track the whereabouts of a criminal suspect from the core area of ​​the county until he got into the car. The whole process...Jiang Yuan looked extremely bored.

I have to say that the number of cases I am doing is gradually increasing, and cases that follow too many rules will consume a lot of willpower.

Jiang Yuan looked at it and couldn't help but take out his mobile phone and start taking a look.

After not looking at it for a long time, hundreds of messages have been posted in many groups.

"Shannan Fingerprint Exchange Group" also has a red [x-on:] symbol.

Jiang Yuandian took a look inside and saw that he was actually Li Zemin.

As a comrade who has fought together in the provincial fingerprint battle, Li Zemin can be said to be a breath of fresh air among provincial document experts.

He and Jiang Yuan smoked Chinese together, traveled through major cases selected across the province, and killed indiscriminately. From the first to the fifteenth day of junior high school, the screams never stopped.

Jiang Yuan opened the "Shannan Fingerprint Exchange Group" with emotion.

Shannan Li is far away. Please help me take a look at this fingerprint. It was taken from the velvet cloth of the trunk by a stupid kid. I highly suspect it is a criminal with a criminal record. 】

Changyang City - Shuidong District - Trace Inspection He Guohua: [Brother Jiang is too busy. In the past two months, he has solved five or six murder cases in a row, and in the meantime he can compare fingerprints. 】

Shannan Li Zemin: [I always pay ten for one. Please ask Jiang Yuan to get a fingerprint, and I will do ten chores for him later. 】

Changyang City - Shuidong District - Trace Inspection He Guohua: [Brother Li, you have passed it. 】

Shannan Li Zemin: [However, I remember to count. Just like the Jiang Yuan Huazi I smoked back then, I wrote down how many of them I had. If I still can’t finish them, I’ll ask my son to return them. 】

Shannan Zhu Huanguang: [x-on:Changyang City - Shuidong District - Trace Inspection He Guohua, you are much older than Jiang Yuan, right? Can you call me brother? 】

Changyang City - Shuidong District - Trace Inspection He Guohua: [Brother Zhu, your criticism is right. I can't mess with my generation just because I'm in the group. We in Changyang City are all called Jiang Ye now. Mr. Jiang, I'm sorry, I will ignore you. "

Provincial Department—Fingerprint Post—Yang Ling: [Call me Jiang Shen. Mr. Jiang was overheard by the security and was easily attacked. 】

Jiang Yuan was very satisfied and read another hundred messages. When they started to change the topic, he forwarded the fingerprint sent by Li Zemin to him.

If some things are too difficult to obtain, it will be difficult to enjoy the glory and happiness it brings.

On the contrary, if you get it easily, the happiness in your heart will be stronger.

It's like demolishing households, it's like demolishing the second generation.

Just like Jiang Yuan.

"Brother Zhuang, give me a computer to use. One with better performance." Jiang Yuan held the fingerprint in his hand and felt that the imaging office was very suitable for processing fingerprints.

There is also a need to process images here, and the newly equipped computers are all top-of-the-line computers from two years ago.

Zhuang Wei immediately let Jiang Yuan out, entered the power-on password, and said with a smile: "The password is a warning signal."

"Okay. Thank you." Jiang Yuan was not surprised at all. It can be said that it is too common for police officers to use police numbers as passwords. Many police officers only got rid of this bad habit after their wives checked their mobile phones.

A simple and incomplete fingerprint does not require any special software. Jiang Yuan put it in and processed it with photoshop first.

Of course, photoshop actually has nothing to do with simplicity. This thing works well and can handle any kind of photos.

The so-called ps originally refers to processing with photoshop. However, photos that may have required a master to deal with in the past have been made fool-proof by various software, so that even those who do not understand technology and have no money can still photoshop a bunch of beautiful photos.

However, the functionality of photoshop has never diminished, and it is not just for processing fat, thin, black and white faces.

field, its application scope is still wide, but many people are not good at using it.

There are too many and too powerful functions that most image processors do not have access to, and the difficulty has increased because of this. Therefore, many people will choose some software that plagiarizes the functions of Photoshop as a replacement. In addition, the price of genuine photoshop is also one of the problems.

"I'm processing fingerprints. A friend just needs it." Jiang Yuan explained to Zhuang Wei and started operating on the computer.

Zhuang Wei looked at it with sadness.

Just like what I had seen before, when Jiang Yuan performed image enhancement, it was difficult for him to understand it. This kind of - well, Zhuang Wei suddenly found that he seemed to understand Jiang Yuan's operation.

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

It’s not just a matter of complexity of the image, but also a matter of familiarity.

Zhuang Wei has also been a policeman for more than ten years. He has seen thousands of fingerprints. He has a very clear and rich experience in his mind about what a fingerprint should look like.

Therefore, when watching Jiang Yuan do image enhancement, he may not have an intuitive feeling. When watching Jiang Yuan do fingerprints, he suddenly understood the direction and goal of Jiang Yuan's operation.

Once you know where the destination is, and then look at the process, the operating space will be easy to understand.

What's more, Jiang Yuan didn't use particularly complicated methods.

He just needs to clean up this fingerprint.

In other words, he doesn't even need to process the entire fingerprint, just making a part of it more beautiful and clear is enough.

With his lv3+lv4 fingerprint analysis method, Jiang Yuan can get enough information even if only one-third of the fingerprints are basically clear - the premise is that the fingerprints to be compared are very complete and clear. And this time, the target fingerprint is a criminal with a criminal record, so there is no need to worry too much in this regard.

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

Anyone who has used Photoshop knows that the software often sacrifices image processing. If only a small part of the image is processed, the difficulty will be reduced.

Therefore, it is easier for Jiang Yuan to get a small piece of very clear fingerprint.

And continuous pieces of fingerprints are actually more advantageous in fingerprint matching.

Zhuang Wei easily saw Jiang Yuan's strategy. At this time, he watched Jiang Yuan do image enhancement further, and he slowly saw into it.

To be honest, Zhuang Wei's foundation is not bad. He studied related majors in college more than ten years ago. Moreover, as we all know, knowledge related to digital image processing, such as Fourier transform and discrete function, has not changed much in the past ten years.

In other words, as long as a person is diligent and studious, and works hard to make progress, even if he is a little stupid, as long as he can understand discrete functions, play with power transformation, and master piecewise linear transformation functions relatively proficiently, he will not be easily eliminated by society even if he spends several times more time than others to learn mathematics.

Just like Zhuang Wei, he actually didn't spend much time studying in the past ten years, but this is mainly because he lost the learning environment.

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

When everything is judged by quantity, 3,000, 6,000, 9,000 or 12,000 are only meaningful at the moment.

Jiang Yuan opened a path for Zhuang Wei.

During the time when Jiang Yuan was doing image enhancement, Zhuang Wei suddenly recalled a lot of knowledge that he thought he had forgotten. He even began to think that being the captain of the image detection squadron was meaningless.

Even if he was the captain of the image detection brigade - of course, if he could really do it, as the first generation of four-eyed old duck, he would still be the leader.

"Almost done." Jiang Yuan stopped.

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

"Well, I'll compare the fingerprints, and it may need to be corrected, but it's basically like this." Jiang Yuan actually knew that Zhuang Wei was stealing, but he didn't care, and he also introduced Zhuang Wei by the way.

Some things, if you can learn them, you don't need to steal them, and if you can't learn them, you can't even install them.

The finished fingerprint image was thrown into the software, and only the feature points were marked once, and the same fingerprint was found at the 8th position.

This is a very high ranking, just as Li Zemin said, the fingerprint is indeed a criminal with a criminal record.

It has to 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 mobile phone. Zhuang Wei was a little dazed and asked: "Did you get it right?"

"Yes."

"Hmm... murder case?"

"I don't think so. I didn't ask about the specific case. I'll tell Brother Li." Jiang Yuan took out his mobile phone and called Li Zemin.

Li Zemin answered almost immediately.

Li Zemin's amplified laughter came from the receiver: "Hahahaha, I knew that it would only take a few minutes for you to do fingerprints, Jiang Yuan. Did you get it right?"

"Yes, but it took almost two hours." Jiang Yuan laughed and said, "We have to be more accurate in time, otherwise, you will say that I am negligent."

"How is it possible? From the first time you handed me a cigarette, I knew that I had made friends with you."

"Come over on business trips when you are free, please smoke a cigar."

"Good guy, wait... Oh, I saw the fingerprints you submitted in the background, and the expert review is not finished yet. OK, I will go and notify the arrest."

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 requirements for the accuracy of fingerprint evidence in China are still very high.

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

"It must be a murder case. How can I ask you for a small case? It's just a current case. Judging from the scene, it should be a habitual offender. The crime has escalated..."

Li Zemin said a few simple words, hung up the phone quickly, and went to report the situation.

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

"That's true." Zhuang Wei smiled with a hint of helplessness: "Who would have thought that a fingerprint expert couldn't make it, and had to ask someone to compare it, it was a murder case."

Buzz.

Jiang Yuan's phone lit up.

"Shannan Fingerprint Exchange Group" flashed red again:

Shannan Li Zemin: [Thanks to my brother Jiang Yuan for matching a murder fingerprint for our city, throw flowers! ]

Changyang City-Shuidong District-Trace Inspection He Guohua: [Jiang Shen, yyds, throw flowers! ]

Shannan Zhu Huanguang: [The review passed. Throw flowers]

Provincial Department - Fingerprint Post - Yang Ling: [Ningtai Jiangyuan, fierce and fierce. ]
