Yang Yanzheng was engrossed in the cable, and a small head suddenly appeared in his field of vision, and his black hair was like a mosaic, blocking half of his vision!

Luoluo, like other friends of the same age, is full of strong curiosity about the world, of course, she is more interested in what her father does, and when her mother is not paying attention, she leans in, her eyes are still wide open, wanting to see what her father is doing.

At this time, the little girl noticed that her father's movements had stopped.

Why doesn't it move?

Luoluo looked up at her father in some confusion, but as soon as she looked up, she saw that her father was looking at her funny, and their eyes met, and the little girl shrank in fear as if a mouse had been caught by a cat.

But the expression on her pink little face was interesting, I saw the big eyes that flashed with the light of exploring the unknown and smiled, and the cheeks didn't know whether it was because of shyness and shame, or because of excitement and joy, they were all red, reflecting her tender white skin like clotted fat, it looked like a little apple, so cute that people wanted to hold it and take a bite!

"Oops...... Hehe...... "I only heard the little girl's delicate scream, and she turned her head and ran to her mother, threw herself between her mother's legs, and hid her little face shyly.

Peeking at her father's work was discovered, she seems to be a little worried that her father will blame her!

This immature and excited cry, this naughty and cute action, Dai Guoxun and Yang Lin in the back couldn't help but smile slightly, as if the purest softness in their hearts was touched.

Xia Yu reacted, she bent down, leaned into the little girl's ear, and gently educated: "Don't disturb your father's work! Otherwise, otherwise your mother will have to take you outside to play, and it's not good to affect your father!"

For Luoluo, it would be more interesting to walk around the park outside! However, for Xia Yu, she preferred to stay and take a look at Yang Yan's busy back.

"Well, it's not good, yes, you want to poop......" The little girl pouted, her voice rose slightly, but she found that after talking to her mother, she weakened again, her fingers intertwined, and she looked at her mother pitifully.

"Mom didn't ask you if you were okay, but said that you can't affect Dad's work, and there are so many uncles and uncles!" Xia Yu was amused by the little girl's "not good".

"It's okay, we don't affect here, it's lively to have a child here. Yang Lin saw that Yang Yan and Xia Yu were brought over by Dai Guoxun, and thought they were related households, so he took the initiative to say.

"Then you have to be well-behaved!" Xia Yu gently rubbed Luoluo's thin shoulders and said gently.

In Luoluo's opinion, the iron-faced and selfless mother is not as easy to talk as his father, but now his father is working! Luoluo can't go to his father to hug and ask for comfort, in the face of those strange uncles and grandfathers, the little girl finally stood beside her mother obediently, holding her mother's fingers with her little hands, and then continued to look at the room.

Seems to have a TV?

At this moment, I found that on the desk where my father was busy, there were several monitors, all of which were shining with color pictures.

It's just that these "TVs" don't seem to look as good as they do at home......

Children also know how to choose,Luoluo's big clear and bright eyes,You can also distinguish the quality of these "TVs"。

The picture quality is not good, and the picture is not as clear as the TV at home, and the color is not bright enough.

The show is not good, why don't you show cartoons? Luoluo likes to watch cartoons!

The pictures on the TV didn't seem to move, and after the little girl looked curiously for a while, she withdrew her gaze and glanced at her mother.

She wants to watch cartoons, but now Luoluo doesn't dare to disturb her father, her mother is fierce, staring at it!

Not to mention the villain with a simple world and rich ideas, Yang Yan has already connected a keyboard here, and entered a line of code on his installed high-performance laptop, and then, the picture on several monitors jumped up, switching from video surveillance to a simple computer desktop, similar to Yang Yan's computer screen.

Afraid that Dai Guoxun and Yang Lin would not understand, Yang Yan turned his head and explained to them: "Now it is a synchronization, in order to facilitate the background retrieval and transmission of these surveillance videos to our remote server, I need to bridge my computer with these computers." ”

In fact, Yang Yan's computer was used to control these monitoring computers, but Yang Yan felt that it was too straightforward in front of the police, and it was not good to use some hacker terms, so he said it a little more tactfully.

But no matter what he said, no one on the scene could understand Yang Yan's explanation, and everyone nodded as if they didn't understand.

"Can these surveillance videos see people's faces clearly?" Yang Lin heard Dai Guoxun talk about the logic of Yang Yan's system to help find relatives, and couldn't help asking, "Normally, shouldn't you use those face recognition devices like those at the entry and exit ports?"

"If you want to replace the equipment, it's too costly!" My current idea is to use the existing equipment and provide assistance to people looking for relatives within our means. Yang Yan explained to the other party a little shyly, "And the surveillance video is actually not blurry, the blurry image we see on the monitor, it is because the resolution of the decoder and the monitor is not good enough!"

In order to support his claim, Yang Yan also retrieved a surveillance video file on his computer and opened it with the playback software he specially wrote for surveillance video.

Soon, a PS-like interface with complex toolbars and editing areas popped up on the desktop.

And the surveillance video, which also occupies most of the picture, is played in front of everyone's eyes.

Yang Yan's laptop screen is a bit small after all, Yang Lin has to walk behind him to see it, and Dai Guoxun is also holding the spirit of learning and exploring, he took out the brown reading glasses he took off before from his pocket, put them on, and looked at it intently.

"It's really much clearer!" Yang Lin exclaimed.

"In fact, its video file stores a lot of information, and we can also take a screenshot and enlarge it in this way!" Yang Yan said as he swiped the mouse and pulled a box in the video screen.

At this time, everyone was surprised to see that just like the surveillance of the Ministry of Security in the movie, the box was enlarged and occupied the original picture.

At first, it was still relatively blurry, mosaic and sawtooth coexisted, but just like Google Maps, the mosaic gradually disappeared, and the picture became clearer little by little!

At this time, the faces in the picture can be seen more clearly!

"It can also be processed, I wrote a smart fix for it to improve the clarity. Yang Yan clicked a button with the mouse.

In fact, shortcuts can be used, but for the sake of demonstration, Yang Yan patiently made the steps one by one to show them.

I saw a line like a laser sweeping on the face screen, the background did not change much, the face became clear, and it was almost the same as the ID photo, you can see his facial features clearly!

Can you also enlarge and make a blurry surveillance video clearer?

That's amazing!

Yang Lin and Dai Guoxun were not calm, their eyes widened and they looked at Yang Yan's computer screen.
