Xu Yun didn't dare to delay when he learned that it was a missing case, so he hurriedly said hello to Song Yupeng and asked him to start running the program, and then saw that the image on the screen was automatically enlarged and gradually became clearer, and finally it was completely like a photo taken with a high-definition camera.

In addition to being able to see his face completely, even the details of the clothes on his body have been restored.

This time, in order to increase the restoration effect of other types of images, in addition to updating the algorithm model, a large amount of image data was also fed.

If it weren't for the company's personnel to assist, he would still be in charge of everything as before, and I am afraid that it would be difficult to completely complete the update and upgrade of the algorithm model after waiting for another month.

And if only the first portrait restoration model is used, then at most the suspect's face will be restored.

But now it's the whole body.

With details such as body type and clothing, it is undoubtedly more convenient to find.

"I didn't expect you to be able to restore the image to such an extent, it really gave me a big surprise."

When Li Jinghong saw the restored surveillance picture, he did not hide the joy in his eyes and on his face.

As a grassroots police officer, he could only rely on personal experience to find images that he could not distinguish in the past, and the difficulty of finding them can be imagined.

Therefore, I don't know how many old cases have been backlogged.

If this kind of technology had been available at that time, at least it would have been able to give justice and comfort to many families.

However, he also understands that this is not the time to reminisce, and that it is important to deal with the case first and find the missing person.

The thought is here, when the command is given.

"Immediately transmit this image to all the grassroots police officers around the place where the incident occurred."

"Call up all surveillance footage within a five-kilometer radius of this location."

"By comparing the images through the master control system, it is necessary to determine the location of the target person at the moment as soon as possible."

"It's the Director."

The dispatcher sitting in front of the console answered, and then hurriedly executed.

But at this time, he saw Ma Gaoke suddenly stand up, and looked at Xu Yun who was not far away and asked: "May I ask Mr. Xu, how can I be sure that the restored portrait is exactly the same as the real person, if there is a large error, wouldn't it disturb the direction of our investigation?" ”

Hearing this, Li Jinghong was also a little silent.

Ma Gaoke's words do make sense, the original target person's face cannot be distinguished by the naked eye due to the aging of the monitoring equipment, and the image is clearly repaired by the algorithm model, but no one can be 100% sure that the two are exactly the same before finding the real person. A number of police officers identified this restoration map to find someone, and it is inevitable that the image will be distorted and the best rescue time will be missed.

Xu Yun naturally believes in his own technology, but he can't get the safety certificate of the missing person.

After a moment's thought, he replied earnestly.

"I believe I can't go wrong with my technical model."

"But you can also pay more attention to your clothes when looking for your target, so you have a double layer of insurance."

"Don't worry."

After Li Jinghong listened to Xu Yun's words, his brows stretched again.

At the same time, he was relieved: "The grassroots cadres and police in our city have rich experience, and they will make comprehensive judgments." ”

Xu Yun nodded, and continued to stand in the hall with the two directors patiently waiting for the results.

Not much.

The dispatcher's voice full of surprise rang out in the hall.

"Report to the Director."

"We were able to find surveillance footage that matched the physical characteristics of the target person."

"Quickly put the screen on the screen." Li Jinghong forcibly suppressed the excitement in his heart and immediately ordered.

In the next second, a real-time monitoring screen appeared in the middle of the screen.

You can see that this is a surveillance footage from the inside of the bus, in which a middle-aged man is sitting in the back seat, and the restored image is almost identical twins.

There is also a little boy sitting next to the key.

It is the missing person in the case.

Ma Gaoke's eyes widened the moment he saw this picture, and he only felt shocked and incredible in his heart.

Unexpectedly, the recovery level was almost 100%.

He previously questioned Xu Yun's deep 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.

When you can see the true effect of restoration, these problems are no longer a problem.

Because he knows very well what this technology means for the public security system.

Compared with Ma Gaoke's shock, Li Jinghong still maintained a calm and composed mind.

After determining the status and location of the missing person, an order for rescue action is quickly issued.

"Contact the bus driver."

"Notify the nearby police officers to support, and be sure to ensure the safety of all personnel."

"It's the Director."

Having thoroughly grasped the initiative, it can be said that for experienced police officers, it can be said that carrying out this kind of action could not be simpler.

It didn't take long for the news of the safe rescue of the missing person to arrive.

From getting the news to solving it safely, it only took a short ten minutes, and this kind of case would never be thought of in normal times.

As the tense nerves relaxed again, Li Jinghong couldn't help but pat Xu Yun's shoulder, his eyes were full of appreciation and pride: "Jingzhou City really needs a hundred young and promising talents like you, and this time it really helped us a lot." ”

"Director Li."

"This is just the beginning of testing." Xu Yun felt the weight coming from his shoulder, and grinned boldly to Li Jinghong.

Li Jinghong was stunned at first when he heard this, and then his face was full of smiles: "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 one of the actual scenarios.

It is not yet possible to prove the effectiveness of the algorithmic model.

So in the following time, under the witness of everyone, the image restoration test was carried out through several practical cases.

Among them were suspects who only had their faces photographed at night.

A battery terminator that deliberately obscures part of the face.

Old black-and-white photographs of suspects archived over a period of more than a decade.

And there is no doubt that they have all been restored to their original appearance in the face of intelligent image restoration technology.

There's nothing to hide.

The test lasted until just about one o'clock in the afternoon, and the powerful effect impressed everyone present.

At the same time, it marks that this key project of the city responsible for Deepin Technology has successfully passed the acceptance.

It is conceivable that when the follow-up results of the Jingzhou City are announced, it will cause some kind of discussion across the country.

Since it happened to be time for dinner, after the test, Li Jinghong took the initiative to invite Xu Yun, Meng Songyan and other company employees to stay in the public security restaurant downstairs to eat.

Xu Yun thought that he would have to go back to school in the afternoon, so he agreed to come down and fill his stomach.

……

In the internal restaurant downstairs, Ma Gaoke deliberately sat in front of Xu Yun, although he had made a lot of meals, he didn't have the slightest intention of eating.

Putting down the chopsticks, he hesitated for a moment, and suddenly asked Xu Yun in a deep voice.

"I wonder if we can use your technology to restore the people in old photos to their current appearance."

"It's very important to me."

Seeing that Ma Gaoke's attitude had changed so much all of a sudden, Xu Yun still didn't react, and was just about to open his mouth to answer when he heard Li Jinghong on the opposite side add with a serious expression.

"Lao Ma was in the criminal investigation team when he was young."

"Back then, due to various factors, several cases in his hands could not be detected and sealed, which also became a heart disease for him."

"Today, seeing that the technology you developed has such an effect, I want to use this as a breakthrough to restart the investigation."

"You don't have to be stressed, just tell the truth."

Listening to all Li Jinghong's words, Xu Yun's mood couldn't help but be a little heavy.

I never thought that Deputy Director Ma, who seemed to be serious and difficult to get along with, still had this kind of thing buried in his heart.

Restoring the restored portrait to its appearance after a few years or even more than ten years is nothing more than an appropriate adjustment of the algorithm model, and it is not too much work, and the value behind the key thing is immeasurable.

Thinking about this clearly, Xu Yun immediately said categorically: "Our company can do what Deputy Director Ma said, but it may take a few days to wait." ”

"Can it really be done?"

"Great."

Hearing this result, Ma Gaoke's emotions were a little out of control at first, and after quickly adjusting, he said lightly: "I've been waiting for so many years, where will there be a few days of difference." ”

After speaking, he seemed to think of something, and then added: "At that time, Li Bureau and I will apply to the city to award you representatives of advanced companies in Jingzhou City and outstanding young people as awards in addition to projects." ”

"Thank you so much to the city." Meng Songyan's face immediately appeared with joy when he heard this, and he hurriedly thanked him.

"You deserve it, come and eat."

Li Jinghong smiled at the corner of his mouth, and in response to Meng Songyan's words, he immediately beckoned a few people to solve the meal in front of him first.

Although Xu Yun didn't know what the use of this outstanding young man was, he thought that his mother would be very happy when he took the honorary certificate home.

So I gladly accepted the honor, and then picked up the chopsticks and feasted.

——

Coming out of the public security building in the afternoon, Xu Yun took the business car rented by the company and returned to school on time.

In addition to ensuring the normal operation of the portrait beautification model on the Huya, the parameters of the intelligent image restoration model are modified, so as to complete the needs of Ma Gaoke as soon as possible to achieve portrait restoration more than ten years later.

With the comprehensive upgrade of the monitoring system in Jingzhou, the official also announced that the investigation of the dust case will be restarted in the near future.

As soon as this news was made public, it was immediately supported by the whole network, and many netizens are still calling on other cities to learn.

Compared with the hot search in the city, Xu Yun has returned to normal campus study life at the moment.

And in the new week, I walked into the classroom of the sophomore ordinary differential equation professional class of 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 is a state that really makes people feel numb, and I don't know what kind of changes will be caused by having an extra junior in the class.

If you change to someone else, you may not feel anything, but the key is that Xu Yun's reputation in the mathematics department is too great.

Thanks to the eccentric 146 for the 100 coin tip, thanks to Cai Xiaolong for the 100 coin tip.
