Chapter 221 Clear mugshot
A scene from the fingerprint battle between the province and the department was staged again.
The light green data flow was like a mountain waterfall, filling the entire computer screen, as well as the pupils of Liu Guodong, Wu Kaiyue and Chen Kun.
"This..."
Wu Kaiyue opened his mouth wide. This was the first time he had seen an image processed in this way.
Chen Kun was also stunned as he stared at the data stream flowing rapidly on the computer screen.
Chen Kun studied computer programming when he was in college, and later studied image processing as a graduate student.
This is also the reason why Chen Kun can become the number one technical expert in the scout team.
I have been playing with computers since I was in college. After so many years of experience, I became the first person in technology in a city bureau’s photo investigation team.
It is precisely because of this background that Chen Kun understands more clearly what Lu Chuan is doing at this moment.
"Are you doing low-level data shunting?"
Lu Chuan nodded: "Only by shunting the bottom-level data of the image can we carry out the next step of data enhancement."
Lu Chuan answered Chen Kun's question, His hands didn't stop, he kept tapping the keyboard, and carried out the data transfer that Chen Kun said little by little.
“The image pixels themselves are too low, so we can only enhance the underlying data, and then convert the data stream into an image through transformation.”
“In this way, we can get what we want with a high probability Standard image.”
With Lu Chuan's operation, the data flow on the computer screen has been divided, and Lu Chuan began to perform the data enhancement just mentioned.
This is the hardest part of all operations.
This time, it was Old God Liu Guodong’s turn to cross his arms and look at Lu Chuan processing the data with a confident look.
That kind of indifference and indifference, as if what Lu Chuan did was just trivial.
There is also a feeling, look, this is the cub I brought.
Looking at it, Wu Kaiyue felt inexplicably sour.
Turning to look at Lu Chuan, who had already completed the final step of data conversion, Wu Kaiyue suddenly had the idea of catching him into the Picture Detective Brigade.
It’s just...
He knows, he can only think about it.
The future of the map reconnaissance team is really not as good as the current survey.
In the Haizhou City Criminal Investigation Detachment, the two were established at about the same time, and even the Visual Investigation Brigade was established earlier.
But after so many years, the first captain of the Scout Group has retired.
As for me, I am the second one.
Not a single one was promoted.
Looking at the current survey office, although the number of people is not as large as that of the map reconnaissance brigade, because the establishment is too small, it is not even qualified to set up a current survey brigade, no, a current survey squadron.
But among the several office directors, the highest one is now the deputy director in charge of criminal investigation of the Haizhou City Public Security Bureau.
This is the gap.
There is a saying that in the public security system, there has always been a saying that political workers will be in vain until they grow old.
Wu Kaiyue said that if you are a picture scout, you will have no place to stay until you grow old.
People who play with words might be able to write their own articles, but what about those who are graphic detectives?
When you get old, do you post photos to others?
The more he thought about it, the more he felt that his future was bleak. Wu Kaiyue let out a long sigh.
Hey...
"It's done!"
When Wu Kaiyue sighed, Lu Chuan's digital image conversion was finally completed.
The progress bar that converts data into an image reaches the last percentile.
The data stream filling the screen disappeared, and a picture appeared.
"This..."
Wu Kaiyue looked at the photos on the screen with some stuttering.
Liu Guodong was also a little surprised.
When Lu Chuan was identifying and analyzing fingerprints in the field survey office, Liu Guodong knew that Lu Chuan had this skill.
But he didn't expect that Lu Chuan was so good at image enhancement.
"Brother Chen, do you think this photo can be used as a standard photo?"
At this moment, Chen Kun, like Wu Kaiyue, stared at the photo on the screen in stunned silence.
Having been a picture detection technician for so many years, he knew for the first time that using computer technology can enhance pictures so clearly!
"Yes, of course I can, this is so powerful!"
Chen Kun was called back to reality by Lu Chuan's words, Brother Chen.
It’s worthy of receiving first-class individual merit twice! This is the gap, this is the strength.
Most people who play with technology don’t know how to use their brains. It’s not that they don’t know how to do it, but more often than not they don’t want to.
But what this kind of person admires the most is a ruthless person with the same skills.
Lu Chuan is obviously the technical ruthless person that Chen Kun admires.
The difference between Lu Chuan and Chen Kun is that he also likes to twist his mind.
Taking out two packets of Huazi, Lu Chuan stood up and handed them to Wu Kaiyue and Chen Kun: "Team Wu, Brother Chen, thank you so much."
"If it weren't for your help, I would be here now Kan can’t do it at all, now it’s better.”
Wu Kaiyue felt a little embarrassed.
I don’t seem to have done much.
Chen Kun is more natural, after all, he also does a job.
But for Hua Zi, he felt it was not necessary.
Usually he only smokes cigarettes that cost ten yuan a pack, Hua Zi... is a bit extravagant.
"There's no need to smoke. I haven't thanked you for the plug-in program you gave me."
"Haha, Brother Chen is too polite. It's not worth mentioning. It's not worth mentioning."
"The computer we are surveying over there is really not good. It stops working after a few attempts. Unlike yours, with such a large amount of data, it will be fine no matter how you run it."
Lu Chuan is telling the truth.
Chen Kun’s computer configuration is really high.
When he was processing the image just now, it took up a lot of memory, but he didn't even hear the sound of the fan on his computer.
"Chen Kun, take the cigarette, this guy has nothing but money, haha."
Liu Guodong laughed and put the cigarette into Chen Kun's hand.
In the entire criminal investigation detachment, the detachment leader only smokes cigarettes worth thirty yuan.
It’s not impossible for Qin Yong to slap Huazi, but the key is that he doesn’t dare.
So when you want to smoke, go to the spot survey office.
As long as Lu Chuan is here, there will definitely be no shortage of unpacking Huazi on the desks of Liu Guodong, Yang Sen and Lao Bai.
A few people chatted for a while, mainly Chen Kun asked for advice. No, it should be said that they exchanged image processing skills, and Liu Guodong and Lu Chuan went back.
The pictures of the suspects in Sun Yuting’s fraud case will also be sent to the QZ City Economic Investigation Detachment.
Contrary to what is shown in the TV series, in reality there is no system that can compare identities by inputting photos into a system.
Whether it is criminal investigation or economic investigation, what they can share is the wanted system.
With this system, the police station can check.
But the identities of the people in the system are confirmed, and the identity of the suspect in the Sun Yuting fraud case is uncertain.
Only after comparison and confirmation of the identity of the other party, the person can be entered into the wanted system for wanted arrest.
The comparison here requires a blacklist.
At the airport, the immigration control unit has this system.
When a person goes through check-in and entry-exit procedures, personal information will be collected and facial authentication will be performed.
Once the comparison with the blacklist is successful, relevant information will be sent to the corresponding public security unit that issued the early warning.
After that, the arrest can be made.
But this blacklist system has very high requirements for face matching.
Otherwise, it would be a joke if a person who has not committed any crime is included in the blacklist.
This is also one of the reasons why the QZ City Economic Investigation Detachment has not confirmed the identity of the other party after more than a year.
The deputy captain of the QZ City Economic Investigation Detachment, looking at the photos from Haizhou City, suddenly had the idea of pinning the QZ City Picture Investigation Team on the ground and rubbing it.
Is the gap that big?
What's more, he is still an amateur, a current detective doing the image enhancement.
Putting his mind at ease, Wang Hai asked Sun Xiaotao to enter his mugshot into the blacklist.
Of course, it does not mean that you will definitely find the other party by entering it into the list.
You have to wait until the target person takes a plane or enters or exits to collect facial information.
Of course, you can also take the high-speed rail. Many high-speed rail stations now also have face collection systems.
Facial information can also be collected while riding the high-speed train through face verification.
But ordinary trains will not work, and those using ID cards or tickets will not work.
