Xu Yun didn't dare to delay when he learned that it was a missing case. He hurriedly said hello to Song Yupeng and asked him to start running the program. Then he saw the image on the screen automatically enlarged and gradually became clearer. In the end, it completely looked like Photos taken with a high-definition camera.
In addition to being able to see the face completely, even the details of the clothes on the body have been restored.
This time, in order to increase the repair effect of other categories of images, in addition to updating the algorithm model, a large amount of image data was also fed.
If it were not for the assistance of company personnel, he would still be responsible for everything as before, and it would be difficult to completely complete the update and upgrade of the algorithm model even if he waits for another month.
And if only the first version of the portrait restoration model is used, then the suspect's face can be restored at most.
But now it's the whole body.
With detailed information such as body shape and clothing, it will undoubtedly be easier to find.
"I didn't expect that you could restore the image to this extent. It really gave me a big surprise."
When Li Jinghong saw the restored surveillance footage, he did not hide the joy in his eyes or face.
As a grassroots police officer, he could only rely on personal experience when encountering images that he could not distinguish. You can imagine how difficult it is to find a needle in a haystack.
So I don’t know how many old cases are backlogged.
If this kind of technology had been available at that time, it would have at least given justice and comfort to many families.
However, he also understood that now was not the time to reminisce. The most important thing was to deal with the case first and find the missing persons.
The thought stays here, and the command is issued immediately.
"Immediately transmit this image to all grassroots police officers around the incident."
"Retrieve all surveillance footage within a five-kilometer radius of this location."
"By comparing the images through the master control system, the location of the target person at this moment must be determined as soon as possible."
"It's the director."
The dispatcher sitting in front of the operation desk responded and quickly started executing.
But at this moment, Ma Gaoke suddenly stood up, looked at Xu Yun not far away and asked: "How can Mr. Xu be sure that the restored portrait is exactly the same as the real person? If there is a big error, wouldn't it confuse us?" The direction of investigation?"
Hearing this, Li Jinghong was also a little silent.
What Ma Gaoke said does make sense. The original target character's face cannot be distinguished by the naked eye due to the aging of the monitoring equipment. The image intelligently repaired by the algorithm model is clear, but no one can be 100% sure that the two are exactly the same until the real person is found. . If several police officers look for this restored picture, it is inevitable that the image will be distorted and the best rescue time will be missed.
Xu Yun naturally believed in his own skills, but he couldn't provide a safety certificate for the missing person.
Think for a moment and answer seriously.
“I trust my technical model to be infallible.”
"But you can also pay more attention to clothes when looking for a target, so you have a double layer of insurance."
"Do not worry."
After listening to Xu Yun's words, Li Jinghong's brows widened again.
While responding, he felt relieved: "Our city's grassroots police officers have rich experience, and they will make comprehensive decisions."
Xu Yun nodded and continued to stand in the hall with the two directors and patiently waited for the results.
Not long after.
The dispatcher's surprised voice sounded in the hall.
"Report to the director."
"We successfully found surveillance footage that matched the physical characteristics of the target person."
"Put the picture on the screen quickly." Li Jinghong suppressed the excitement in his heart and ordered immediately.
In the next second, a real-time surveillance screen appeared in the middle of the screen.
It can be seen that this is a surveillance image from inside the bus, in which a middle-aged man sitting in the back row and the restored image are almost identical twins.
The key is that there is a little boy sitting next to him.
It was the missing person in the case.
Ma Gaoke's eyes widened the moment he saw this picture, and he felt shocked and incredible.
I never expected that the degree of recovery was almost 100%.
He had previously questioned Xu Yun's in-depth technology, believing that the new company and new technology were not stable, and the losses would be huge no matter what happened during the investigation of the case.
Once you see the real effects of recovery, these problems will no longer be a problem.
Because he knows exactly what this technology means for the public security system.
Compared with Ma Gaoke's shock, Li Jinghong still maintained his coolness and composure.
After determining the status and location of the missing person, a rescue operation order was quickly issued.
"Contact the bus driver."
"Notify nearby police officers for support and ensure the safety of all personnel."
"It's the director."
Having completely taken the initiative, it can be said that it is extremely simple for experienced police officers to execute this kind of action.
Not long after, news came that the missing persons had been safely rescued.
From getting the information to safely solving it, it only took more than ten minutes. This kind of case would never be imagined in normal times.
As the tense nerves relaxed again, Li Jinghong couldn't help but patted Xu Yun's shoulder, his eyes full of appreciation and pride: "Jingzhou City really needs a hundred young and promising talents like you. This time It really helped us a lot.”
"Director Li."
"The test has just begun." Xu Yun felt the weight on his shoulders and said boldly to Li Jinghong with a grin.
Li Jinghong was startled when he heard this, and then his face was filled with a smile: "Then I want to see how many surprises you have."
As Xu Yun said, the test of the intelligent surveillance image restoration function has just begun.
After all, it was just a situation in a real scene.
The effectiveness of the algorithmic model cannot yet be proven.
So in the following time, under the joint witness of everyone, image restoration tests were conducted through several actual cases.
This includes the suspect whose profile was only photographed at night.
A battery terminator that intentionally covers part of its face.
Old black and white photos of suspects archived over more than ten years.
And there is no doubt that they can restore their original appearance in the face of intelligent image restoration technology.
Nothing to hide from.
The test lasted until almost one o'clock at noon, and its powerful effect impressed everyone present.
It also marks that this key city project, which is responsible for Deepin Technology, has successfully passed the acceptance inspection.
You can imagine what kind of discussion it will cause across the country when Jingzhou City announces the follow-up results.
Since it was dinner time, after the test, Li Jinghong took the initiative to invite Xu Yun, Meng Songyan and other company employees to stay downstairs in the public security restaurant for dinner.
Xu Yun thought that he would go back to school in the afternoon, so he agreed to come down and fill his stomach before talking.
…
In the inner restaurant downstairs, Ma Gaoke specially sat in front of Xu Yun. Although he ordered a lot of food, he had no intention of eating.
He put down his chopsticks, hesitated for a moment, and suddenly asked Xu Yun in a deep voice.
"I want to know if I can use your technology to restore people in old photos to their current appearance."
"This is very important to me."
Seeing such a big change in Ma Gaoke's attitude, Xu Yun still didn't react. He was just about to answer when he heard Li Jinghong from across the way add in a serious tone.
"Lao Ma was in the criminal investigation team when he was young."
"Due to various factors, several cases at hand could not be solved and were sealed. This also became a worry for him."
"Today I saw that the technology you developed has such an effect, so I thought of using this as a breakthrough point to restart the investigation."
"You don't need to feel any pressure, just tell the truth."
After listening to all Li Jinghong's words, Xu Yun felt a little heavy.
I never thought that Deputy Director Ma, who seemed serious and difficult to get along with, actually had this kind of thing buried in his heart.
Restoring the restored portrait to its appearance several years or even more than ten years later is nothing more than making appropriate adjustments to the algorithm model. It is not a huge workload. The value behind this key matter is immeasurable. of.
After thinking about this clearly, Xu Yun immediately said firmly: "Our company can do what Deputy Director Ma said, but it may take a few days."
"Can it really be done?"
"Very good."
Hearing this result, Ma Gaoke's emotions were a little out of control at first. After quickly adjusting, he said calmly: "I have been waiting for so many years. How could it be just a few days behind?"
After saying that, he seemed to have thought of something, and then added: "At that time, Director Li and I will apply to the city to award you with Jingzhou City Advanced Company Representatives and Outstanding Youths, as rewards in addition to the project. .”
"Thank you so much to the city." Meng Songyan's face immediately lit up with joy when he heard this, and he quickly thanked him.
"You deserve this, come and eat."
With a smile on his face, Li Jinghong responded to Meng Songyan and immediately asked a few people to finish the food in front of him.
Although Xu Yun didn't know the use of this outstanding young man, he thought that his mother would be very happy when he took the honorary certificate home.
So I happily accepted the honor, then picked up my chopsticks and started eating.
——
After coming out of the public security building in the afternoon, Xu Yun took the commercial vehicle rented by the company and returned to school on time.
After that, the company was much more relaxed. In addition to ensuring the normal operation of Huya's portrait beautification model, it also modified the parameters of the intelligent image restoration model so that it could complete Ma Gaoke's needs as soon as possible and achieve the goal more than ten years later. Portrait restoration.
With the comprehensive upgrade of Jingzhou City's surveillance system, officials have also announced that they will restart the investigation of dusty cases in the near future.
Once this news was made public, it immediately received support from the entire network, and many netizens also called on other cities to learn from it.
Compared with the trending searches in the city, Xu Yun has now returned to his normal campus study life.
And in the new week, I walked into the classroom of the sophomore ordinary differential equations course in the Department of Mathematics.
It is worth mentioning that this professional course is still in charge of Tang Yanshan.
It's just that compared to Xu Yun's restraint when he came to the new environment, for the sophomore seniors, it was a state that really made people feel numb. I don't know what changes will be caused by adding another junior to the class. .
If it were someone else, maybe it wouldn't matter, but the key point is that Xu Yun's reputation in the mathematics department is too great.
Thanks to Weird 146 for the 100-point reward, and thanks to Cai Xiaolong for the 100-point reward.
