Seeing Yang Yan's display, Xia Yu was not as surprised as Teacher Dai and Director Yang, nor did she flock forward to see what was going on, she just stood behind and looked at Yang Yan's computer screen intently, with an unchanged expression, making it difficult to judge her emotional changes.

"It feels familiar......" Xia Yu thought secretly in her heart, rummaging through her memories.

By the way, almost two years ago, at the time when Luoluo was looking for relatives, didn't Yang Yan take the surveillance video he took back to deal with it? At that time, the quality of the surveillance video was even worse, and when I played it on the computer, I felt that the picture quality was dark and there was more noise (after all, it was night), but after a night, Yang Yan dealt with it and could see the wearing characteristics of the characters clearly, but unfortunately, the angle was not good, and he was wearing a hat, and his face and appearance were not recorded.

Just when Xia Yu was thinking about it, Yang Yan turned his head to look at Dai Guoxun and Yang Lin who were standing behind him, and couldn't help but stand up from the chair.

"Hey, Teacher Dai, Director Yang, why are you standing and watching? Hurry ......up," Yang Yan diligently moved two chairs from the side and beckoned them to sit down, "Teacher, sit down, there are still many functions to be demonstrated later! ”

Not only moved chairs for them, Yang Yan also leaned over and muttered to Xia Yu, asking her to sit down on the wooden sofa that fell behind.

At this time, the director of the People's Park and two people came over with fruits and tea, Yang Lin had communicated with them before, and now they received the "ventilation report" from the security guards in the monitoring room, so they hurriedly brought the prepared things and came to the leaders of the Provincial Public Security Department to be courteous.

"Director Yang, Dai Ju, we are not well entertained, you are here, how can we let you sit on such a hard chair, Xiaoliu, you go, let people go to the conference room and move a few sofa chairs. The director shook Dai Guoxun's hand ashamedly and said, "Dai Ju, why don't you go to our conference room and sit down?"

"Don't make a big fuss, we can make this chair comfortably, we have a backrest, what kind of sofa chair to move!" Dai Guoxun waved his hand, he is a practical leader, he has been working on the front line, and he has never liked these red tape.

Although the dedication failed, the director was still very thick-skinned, and he actively took out a pack of soft China and handed cigarettes to Dai Guoxun and Yang Lin.

When the police, there are few who are not old smoking guns, Dai Guoxun also subconsciously took it, pinched the cigarette with his fingers, and prepared to stuff it into his mouth, and the director next to him had already taken out a lighter and was about to light it for him.

But Dai Guoxun raised his head, and his gaze swept to Luoluo, who was sitting obediently on the wooden sofa behind him, and his left hand holding the cigarette froze slightly.

"There are kids here today, no smoking. Dai Guoxun waved his hand, and skillfully held the cigarette to his ear.

That's right, Xiao Yang's daughter is also here! Yang Lin only remembered at this time, he looked at the fall over there, although he felt a little sorry in his heart, and his addiction to smoking came to his heart, but he still restrained himself, followed Dai Guoxun's movements, and said with a smile: "Listen to Teacher Dai, no one is allowed to smoke today, and the monitoring room will be stinky, and it will not be good for children to smoke second-hand smoke!"

Hearing them say this, Xia Yu, who was already nervously trying to stand up and prepare to take Luo out, slowly breathed a sigh of relief.

The director turned his head and saw Luoluo, just now the little girl was silent by her mother's side, and her sense of presence was weak, so that he ignored this short figure.

"Hey, there are children here, I'm sorry, I won't smoke. The director smiled and put the cigarette back, he seemed to mistakenly think that Luoluo was the granddaughter brought by Dai Guoxun (after all, Dai Guoxun is retired, and he should be in a state of frolicking at home and grandchildren), and he also enthusiastically took out a few oranges and apples from the bag and handed them over, "The child looks so cute, hurry, eat some fruit." ”

Luoluo is not familiar with him, not to mention that this uncle is still a little over-enthusiastic, which makes the little girl feel a little pressure.

I saw Luoluo timidly looking at his outstretched hand, but he dodged in fear, and squeezed his little body into his mother's arms: "Hmm...... Hmmm......"

People don't want it!

Don't stuff it over......

"Thank you, Director Zheng!" Xia Yu took it for Luoluo, but she only nodded politely to the other party.

Director Zheng's interruption was just a small episode, the work was important, Dai Guoxun saw that he had been talking, and couldn't help but glance at Yang Lin, so he coaxed away the director and the people he brought in a few words, and the monitoring room was quiet again.

It's still Yang Yan's sho time!

"The software just now only plays an auxiliary role, making it easier for us to access the monitoring screen. Yang Yan turned to the left and explained to Dai Guoxun, who was sitting there, "But if you want to manually take pictures of human faces and compare them, it will take too much time and energy, so I handed over this repetitive process to the computer to operate, that is, the 'intelligent human recognition' system I designed!"

Yang Yan said it simply, but if you want to realize it, it is not ordinarily difficult!

Of course, the hard work behind this is not shown for the time being, Yang Yan will now open the "intelligent recognition" system he wrote and demonstrate it to Dai Guoxun and Yang Lin.

Since it's just Yang Yan's own programming, there is no trouble to the company's professional art team, Yang Yan's system does not have a cool boot animation, just simply pop up a different from the video software just now, but the same complex interface.

Yang Yan directly gave the two leaders dry goods: "Now we have access to the real-time surveillance video of the gate of the park, which is marked as A10. ”

I saw a video screen inserted in, but what made Dai Guoxun and Yang Lin stunned was that in this video screen, the faces of every tourist were marked with dotted coordinates, there was no error at all, and other flowers and trees were not affected!

At the same time, above the image of each tourist, there is also a box with a dotted line extension, as the visitor walks, their facial features are refreshed and entered into this box over and over again, and it is also 3D imaging!

Yang Yan casually clicked on a frame, and a clear 3D portrait appeared in front of them.

Of course, it is not that there are no defects, because of the angle, some parts of this 3D portrait, such as the neck part below the chin, are covered by mosaics, until the tourist walks out of the monitoring range, and the neck part is still not refreshed!

But Dai Guoxun's eyes are so vicious, he is wearing reading glasses, and he can tell that this 3D portrait is the appearance of the tourist just now: "That's right, it's him, and the facial features are exactly the same!"

Yang Yan explained with a smile: "This is the face extraction function in our intelligent recognition system, after we extract this face data, we can compare it with the lost population photo data in the database, of course, the performance of the computer is not up to such a large computing power requirement, and it needs to be transmitted to the cloud server for further analysis." ”

Now Yang Yan has only completed part of the work, and he has not yet started to connect to the server provided by the Provincial Public Security Department.

Of course, he has already studied and understood the technology of cloud servers, and Yang Yan's later work is not complicated, and even the operating system of cloud servers has been written in advance!

But for Dai Guoxun, who has vicious eyes, Yang Yan's system surprises him far more than that!
