XCMG has made progress on this side for the next day.

In the afternoon of the next day, XCMG received an email from the Ministry's Physical Evidence Center, immediately printed it out, and brought it to Liu Pengcheng: "I just said, the composition is so complex, wear-resistant and lightweight, it's really a big brand!" ”

Liu Pengcheng took a look at it, and it was a reply from the physical evidence center, including the composition and molecular formula of the original physical evidence, and the composition and molecular formula of the sample found by the physical evidence center. Also included is the case of the sample.

It is a cool low-to-mid-range running shoe created by Nike for the millennium. Teenagers, mainly middle school students, are the main sales group, and of course, when they arrive in China, they are "international brand millennial fashion". The price is not cheap!

According to their company's statistics, the sales of this shoe in Hangzhou are okay, from New Year's Day to a month ago, a total of more than 170 pairs were sold.

This shoe is the same for men and women, of course, there are men and women in this sales, because this shoe is based on red, so women buy more in China.

Liu Pengcheng has seen this kind of shoes in many places, and it is hard to believe that Quan Yuhang has sold more than 100 pairs, or Xiao Gu said, as if he has to sell thousands of pairs!

In fact, Kotani is right, even some domestic brands have launched similar shoes.

But what Liu Pengcheng has in his hand is the result of the test of the sole material, which cannot be the same. Finding a suspect from dozens of people is actually very difficult!

Xiao Gu drove the car, went to the city bureau with Liu Pengcheng, and found the Zhao detachment.

The Zhao detachment held the reply letter from the Ministry's Physical Evidence Center in his hand, and his face was full of smiles.

That's easy to do!

gave the results of the appraisal to the Zhao detachment, refused dinner, and Liu Pengcheng and the two returned to the center.

When he got off work, Liu Pengcheng suddenly remembered why Xiao Zhai hadn't moved at all in the past few days! So I went to Xiao Zhai's studio, and there was no sound in it.

Liu Pengcheng knocked on the door, but there was no movement,

So Liu Pengcheng opened the door directly, but there was no lock, and he opened it all of a sudden. So he saw that Xiao Yang was sitting in a wide computer chair, wearing a huge headset and sleeping in the dark. There were no lights in the room, and the light from the 19-inch Philips flat screen monitor made his face and mouth flicker.

Liu Pengcheng walked over to take a look, and was stunned.

The monitor is playing the surveillance video of the intersection of the old Zhaojia community at eight times the speed, and then automatically pauses from time to time, grabs a frame of images with motorcycles and stores them automatically.

This, this, this god himself came out with graphic detection software???

Liu Pengcheng directly took off his headset.

Xiao Zhai continued to sleep, and Liu Pengcheng didn't wake up.

Liu Pengcheng had no choice but to say in his ear: "It's time to eat!" ”

Now Xiao Zhai woke up, his eyes widened all of a sudden, and he wiped the saliva on the side of his mouth with his hand: "I'll make a braised pork!" ”

Then I saw Liu Pengcheng with a black line on his face, and looked around again, only to react to what was going on.

Xiao Zhai was a little embarrassed: "Director Liu, I've stayed up late these days...."

"Okay, okay, I know you forgot to sleep and eat. Let's go, come home with me and eat braised pork. ”

Xiao Zhai said: "I won't bother you, I'll just eat a bite in the cafeteria, and I'll have to come back in a while." ”

Liu Pengcheng said: "Don't talk nonsense. Look at what time it is, and there is only a bottom left of the good food in the cafeteria. ”

At that time, the police canteen was divided into a student canteen and a faculty canteen. But in the evening, everyone basically goes home to eat, that is, the teachers on duty and a few unmarried people eat in the cafeteria, so the amount of dinner prepared is not large, and there are often teachers and staff who go late can only eat fried rice, noodles or quick-frozen dumplings.

Xiao Zhai thought about it, and went back with Liu Pengcheng.

Liu Pengcheng really didn't fool Xiao Zhai, his family did eat braised pork at night. Braised pork stewed vermicelli.

The soft and rotten pork belly that has been stewed and the rich flavor of the wide noodles are a perfect match!

Xiao Zhai made three bowls of rice in a row, and drank another bottle of soda before patting his belly with satisfaction: "Alas, after this meal, I think I can eat biscuit instant noodles for a week again." ”

Liu Pengcheng said: "You are just lazy, the canteen is only a few steps away from our center!" ”

Xiao Zhai said: "You don't understand, once the code starts to be typed, you can't stop." ”

This Liu Pengcheng really didn't understand, but he still said: "I just don't understand it anymore, and I know that it can be saved!" ”

Xiao Zhai's eyes widened: "I should finish it all in one go, go to the cafeteria for a meal and then come back, I can't catch it, I can't catch it, you know?" ”

Well, Liu Pengcheng really doesn't understand.

The iron head is even more incomprehensible. After eating, I went to play with my toys.

After Liu Pengcheng and the two finished eating, Aunt Xu made tea for the two of them, which was the jasmine tea that Liu Pengcheng liked.

Liu Pengcheng said: "So in order to find out the motorcycle, you made your own image screening software? ”

Xiao Zhai said: "It's not difficult, but it takes a lot of effort before grabbing, you have to input all kinds of parameters, images, computers, to put it bluntly, it's still dead, you ask him to find the same motorcycle, red, what does the front look like, he can find it." But once the side one appears, he doesn't recognize it, so he has to enter it again. This one is too much work. ”

It's not AI at all.

Liu Pengcheng said: "Can this problem be solved? ”

Xiao Zhai: "This matter is laborious, not difficult. You have to enter a lot of data, and you have to update it frequently. It's too much work. If someone else has entered the relevant parameters, then we can enter the model of the motorcycle or car we are looking for when we use it. ”

Liu Pengcheng said: "What about the human face? Okay? ”

Xiao Zhai said: "In fact, this kind of software exists, and it has also been put into actual combat, but it is in the stage of strict secrecy, so I am afraid that it will not work if someone deciphers it and finds a way to deal with it." ”

Liu Pengcheng asked, "Is it from a beautiful country?" ”

Xiao Zhai: "How safe the big beautiful country is, how can you use this kind of thing." ”

Liu Peng Chengxin said, wait until next year's golden autumn season to see if you can still say this!

Xiao Zhai said: "It's from David's country, and they use this software to screen whether there are people with big turbans and fireworks among the people who enter the country." ”

Liu Pengcheng said: "Have you ever thought about what we can do with this? ”

Xiao Zhai said: "What can I do, what else can I do, didn't you ask me to find the snitch, I did this?" ”

Liu Pengcheng had no choice but to tell Xiao Zhai about the role and working methods of the graphic detective.

Xiao Zhai's eyes widened: "Brother Liu, tell me a science fiction story, with the resolution of the camera, how can it achieve what you say, it's good to be able to show that the human head is round and not a square, and it can directly identify the identity, how is this possible." Even if there is a high-definition camera, but what is the cost, don't talk about other places, just say Yuhang, how many can you afford? ”

As soon as he said this, Liu Pengcheng also came to his senses. This is the year 2000, and this year has just entered the era of 3 million pixels! You can't shoot at night yet. This year, all mobile phones are still black and white screens, and occasionally a few Blu-ray screens are considered black technology!

Liu Pengcheng was still reflecting on his "great achievements", but Xiao Zhai said: "But I think with the development of science and technology, there will always be a day when your vision will be realized." Now we are choking others enough, and there is no problem with screening cars! ”

Xiao Zhai, who suddenly opened the door to the new world and felt that he had made a very good software, dragged Liu Pengcheng back to his office to view the video screenshots of several motorcycles that had been caught and often haunted near the crime scene.

Seeing the first one, Liu Pengcheng was stunned. The red shoes on this rider's feet are so familiar!
