Jiang Yuan watched the video with the members of the duck team for a while, and was familiar with the new surveillance system.

I have to say that when I watched videos with a few men, I watched sports videos mainly based on men, and without the ball, the rest was pure boredom.

Zhuang Wei operated the software to track the whereabouts of a criminal suspect, from the core area of ​​the county and district until he got on the bus, the whole process...

Jiang Yuan was super bored to see.

I have to say that more and more cases are being done, and cases that are too pertinent will consume a lot of willpower.

Jiang Yuan looked at it, and couldn't help but pull out his cell phone and start looking.

After not watching it for a long time, hundreds of messages have been released in many groups.

The "Shannan Fingerprint Exchange Group" also has a red [@] symbol.

Jiang Yuan clicked in and saw that Li Zemin was actually his.

As a comrade-in-arms who fought together in the provincial fingerprint battle, Li Zemin can be said to be a clear stream among provincial experts.

He and Jiang Yuan were smoking China together, shuttled through major cases selected in the province, and rattled each other, from the first day of the lunar month to the fifteenth day of the lunar month, his screams never stopped.

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

Shannan Li******. Help us check this fingerprint. A silly child took the fingerprint from the trunk velvet cloth. He is highly suspected to be a criminal record.]

Changyang City-Shuidong District-Henjian He Guohua: [My Brother Jiang is too busy. In the past two months, he has solved five or six murder cases in a row. He can also compare fingerprints in the middle.]

Shannan Li Zemin: [I am all one and ten, please give Jiang Yuan a fingerprint, and I will do ten miscellaneous work for him afterwards.]

Changyang City-Shuidong District-Henjian He Guohua: [Brother Li, you have blown it.]

Shannan Li Zemin: [However, I remember counting. Just like the Huazi I drew from Jiang Yuan back then, I wrote many threads. If I can’t pay it back, I will ask my son to pay it back.]

Shannan Zhu Huanguang: [@Changyang City-Shuidong District-Henjian He Guohua, you are one round older than Jiang Yuan, can you call me brother?]

Changyang City-Shuidong District-Henjian He Guohua: [Brother Zhu, you are right to criticize me. I can’t call this generation messy just because I’m in the group. Our Changyang City is now called Master Jiang. Master Jiang, I’m sorry, I won’t @ you.”

Provincial Department - Fingerprint Post - Yang Ling: [Call Jiang Shen. Master Jiang is easily attacked by public security.]

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

If you get some things too hard, 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 a demolition household, it’s like a demolition second generation.

Just like Jiang Yuan.

"Brother Zhuang, use it for me a computer. The one with better performance." Jiang Yuan held his fingerprint and felt that the imaging office was very suitable for processing fingerprints.

There is also a need to process images here. The newly equipped computers are all top-end from two years ago.

Zhuang Wei immediately gave Jiang Yuan one out, entered the boot password, and smiled and said, "The password is a warning number."

"Okay. Thank you." Jiang Yuan was not surprised at all. It can be said that the police use the police number as a password is too common. Many policemen only got rid of this bad habit after their wife checked their phones.

Just a vague fingerprint, and no special software is needed. Jiang Yuan put it in and then used Photoshop to process it first.

Of course, Photoshop actually has nothing to do with simplicity. If this thing is used well, it can be processed by any photos.

The so-called PS originally refers to using Photoshop. However, photos that may have required experts to deal with in the past were later fooled by various software, so that those who do not understand technology and have no money can also PS out a bunch of beautiful photos.

However, Photoshop's functionality has never diminished. It is not only used to deal with fat, thin, black and white faces, but it is still widely used, but many people are not good at using it.

Too many and powerful functions are not enough for most image processors, and the difficulty has been increased. Many people will use some software that plagiarizes Photoshop functions as a replacement. In addition, the price of Photoshop is too expensive is also one of the problems.

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

Zhuang Wei looked at him with sorrow.

Just like what I saw before, when Jiang Yuan made the image enhancement, it was difficult for him to understand it. This - hey, Zhuang Wei suddenly realized that he seemed to understand Jiang Yuan's operations.

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

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

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

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

If you know where the destination is and look at the process, it will be easy to understand the operating space here.

Moreover, Jiang Yuan did not use particularly complicated means.

He just needs to clean up this fingerprint.

Even said that he didn't have to deal with the entire fingerprint, just make some of it beautiful and clearer.

With his LV3+LV4 fingerprint analysis method, even if there is only one-third of the basically clear fingerprints, Jiang Yuan can get enough information - the premise is that the fingerprints being compared are very clear. This time, the target fingerprint is a criminal, 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 this software often sacrifices the processing of images. If you only process a small part of the images, the difficulty will be reduced.

Therefore, Jiang Yuan is more likely to get a small piece of very clear fingerprint.

The continuous patches of fingerprints are actually more advantageous in terms of fingerprint comparison.

Zhuang Wei easily saw Jiang Yuan’s strategy. At this time, he looked at Jiang Yuan further to enhance the image and slowly looked in.

Speaking of which, Zhuang Wei has a good foundation. He studied in college more than ten years ago. Moreover, as we all know, knowledge about 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 studious, hardworking and motivated, even if he is a little stupid, he will not be easily eliminated by society as long as he can understand discrete functions, play power transformations, and master segmented linear transformation functions relatively skillfully.

Just like Zhuang Wei, he has not really spent more than ten years studying, but this is mainly because he has lost the learning environment.

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

When everything is based on quantity as the criterion, 3000, 6000, 9000 or 12000 are only meaningful in the present moment.

Jiang Yuan cut a path for Zhuang Wei.

During the period when Jiang Yuan was doing image enhancement, Zhuang Wei suddenly recalled a lot of knowledge that he had consciously forgotten. He even began to feel that it was meaningless to be the squadron leader of the squadron of the Investigation Squadron.

Even if he is the captain of the Map Investigation Brigade - of course, if he can really do it, as the first four-eyed old duck, he will still take it as the first generation.

"It's almost done." Jiang Yuan stopped.

Zhuang Wei's mind was also clear: "Ah, is it done?"

"Well, I'll compare my fingerprints and may need to be corrected, but that's basically it." Jiang Yuan actually knew that Zhuang Wei was stealing his skills, so he didn't care, so he also introduced a few sentences to Zhuang Wei.

Some things can be learned without stealing them, and they can't even be filled with what they can't learn.

The fingerprint image was thrown into the software, and the feature point was marked only once, and the same fingerprint was found in the 8th position.

This is a very high ranking. As Li Zemin said, fingerprints are indeed from a former criminal.

I have to say that the judicial system of Shannan Province is really doing well in printing fingerprints.

Jiang Yuan clicked on the submission and took out his cell phone.

Zhuang Wei was a little dazed and asked, "Have you won the competition?"

"right."

"Well... a murder?"

"It shouldn't be true. I didn't ask the case in detail. I'll tell Brother Li." Jiang Yuan said, taking out his cell phone and dialed it to Li Zemin.

Li Zemin took it almost instantly.

In the earpiece, Li Zemin's amplified laughter came from: "Hahaha, I knew that Jiang Yuan, you do fingerprints in minutes. Have you won the competition?"

"I won the competition, but it took almost two hours." Jiang Yuan smiled and said, "We have to make the time more accurate, otherwise you have to say I've been neglected."

"How is that possible? I've known from the first time you handed over cigarettes and Huazi, I've decided to hand over your brother."

"You come here for business trips when you have time, please smoke a cigar."

"Good guy, wait... Oh, I saw the fingerprint you submitted in the background. The expert review has not been completed yet. I'll inform the arrest of the person."

Although Jiang Yuan is also a certified fingerprint expert from the provincial department and can do expert review, the fingerprints he made by 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 murder case. Do I have the nerve to invite you in a small case? It's just a case. When you look at the scene, you should be a habitual criminal. The crime has escalated..."

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

Jiang Yuan put down the phone and smiled at Zhuang Wei who was clearly hearing it next to him: "I really didn't expect it to be a murder."

"That's right." Zhuang Wei smiled with a hint of helplessness: "Who could have thought that even a fingerprint expert could not do it. The fingerprint that he wanted to ask someone to compare was a murder case."

Buzz.

Jiang Yuan's cell phone lit up.

"Shannan Fingerprint Exchange Group" flashed again:

Shannan Li Zemin: [Thanks to my brother Jiang Yuan for his fingerprint of the murder case in Bizhong in our city and sprinkle flowers!]

Changyang City-Shuidong District-Henjian He Guohua: [Jiangshen, YYDS, Spread Flowers!]

Shannan Zhu Huanguang: [Review passed. Spread flowers]
Chapter completed!
