It was only the next day that XCMG made any progress.

In the afternoon of the next day, XCMG received an email from the Ministry's Physical Evidence Center. He immediately printed it out and brought it to Liu Pengcheng: "I just said, with such complex ingredients, wear-resistant and light weight, it is really a big brand!"

Liu Pengcheng took it and took a look. It was a reply from the Physical Evidence Center, including the composition and molecular formula of the original physical evidence, the composition and molecular formula of the sample found by the Physical Evidence Center. It also included the condition of the sample.

It is a mid-to-low-end running shoe with a cool appearance created by Nike for the millennium. It is mainly sold to teenagers, mainly middle school students. Of course, in China, it is an "international big-name millennium fashion". The price is not cheap. !

According to their company's statistics, the sales volume of this shoe in Hangzhou is pretty good. From the launch on New Year's Day to a month ago, a total of more than 170 pairs were sold.

This shoe is for both men and women. Of course, there are both men and women in the sales volume. Since the shoe is mainly red, women in China buy more of it.

Liu Pengcheng has seen this kind of shoes in many places. It is hard to believe that more than a hundred pairs have been sold in Yuhang. Or Xiaogu said that the imitations would have sold thousands of pairs!

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

But what Liu Pengcheng had in his hand was the result of the laboratory test of the sole material, which could not be imitation. Finding a suspect from dozens of people was actually very difficult!

Xiaogu drove to the city bureau with Liu Pengcheng and found Detachment Zhao.

Detachment Zhao was holding a reply letter from the Ministry's Physical Evidence Center in his hand, and his face was about to burst into laughter.

This is easy to handle!

After giving the results of the appraisal to detachment Zhao and declining dinner, Liu Pengcheng returned to the center.

When he was getting off work, Liu Pengcheng suddenly remembered that there had been no movement from Xiao Zhai in the past few days! So he went to Xiao Zhai's studio, but there was no sound inside.

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

So Liu Pengcheng opened the door directly, but it was not locked, so he opened it all at once. Then he saw Xiao Yang sitting on a large computer chair, sleeping in the dark with a huge headset on. There was no light in the room, 19-inch The light from the Philips flat-screen monitor made his face and open mouth flicker in and out.

Liu Pengcheng walked over and took a look, and was stunned.

The monitor is playing the surveillance video of the intersection in Lao Zhao's community at eight times speed, and then automatically pauses from time to time, captures a frame of an image with a motorcycle, and automatically stores it.

This, this, this, this great god came up with the photo detection software???

Liu Pengcheng directly took off his headset.

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

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

Xiao Zhai woke up now, his eyes widened suddenly, and he wiped the saliva from his mouth with his hand: "I'll order some braised pork!"

Then he saw Liu Pengcheng, who had a black line on his face. He looked around again and realized what was going on.

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

"Okay, okay, I know you forget to eat and sleep. Come on, come home with me to eat braised pork."

Xiao Zhai said: "I won't bother you. I can just have a bite in the cafeteria and I'll be back soon."

Liu Pengcheng said: "Don't talk nonsense. Look at what time it is. There is not much good food left in the cafeteria."

At that time, the police academy cafeteria was divided into a student cafeteria and a staff cafeteria. But in the evening, everyone basically went home to eat, that is, the teachers on duty and a few unmarried people ate in the cafeteria, so the amount of dinner prepared was not large.

Faculty and staff who leave late can only eat fried rice, noodles or 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 and braised pork with vermicelli in the evening.

The soft and flavorful pork belly that has been stewed and the chewy noodles are a perfect match!

Xiao Zhai finished three large bowls of rice in a row and drank a bottle of soda before patting his belly with satisfaction: "Oh, after this meal, I think I can eat biscuits and instant noodles for another week."

Liu Pengcheng said: "You are just lazy. The cafeteria is only a few steps away from our center!"

Xiao Zhai said: "You don't understand, once you start typing the code, you can't stop."

Liu Pengcheng really didn't understand this, but he still said: "No matter how much I don't understand, I still know that it can be saved!"

Xiao Zhai's eyes widened: "You should finish the fight in one breath. Go to the cafeteria to have a meal and then sneak back. If you can't catch it, you can't catch it, do you understand?"

Well, Liu Pengcheng really doesn’t understand.

Tietou didn't understand even more. After eating, he went to play with toys by himself.

After Liu Pengcheng and two people finished eating, Aunt Xu made tea for them. It was jasmine tea that Liu Pengcheng liked. Xiao Zhai had been working in the capital for a long time, so he was naturally used to drinking it.

Liu Pengcheng said: "So in order to find motorcycles, you made your own image recognition software?"

Xiao Zhai said: "It's not difficult, but it takes a little more effort before crawling. You have to enter various parameters, images, and computers. To put it bluntly, things like computers are dead. If you ask him to find the same motorcycle, red,

He can find what it looks like from the front. But once it appears from the side, he doesn't recognize it, so he has to enter it again. This is too laborious."

It’s not AI after all.

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

Xiao Zhai: "This is laborious, not difficult. We have to input a large amount of various data and update it frequently. It is too laborious. If others have entered the relevant parameters, then when we use it, we will enter the motorcycle we are looking for.

Or the model of the car will suffice.”

Liu Pengcheng said: "Where's the human face? Is that okay?"

Xiao Zhai said: "Actually, this kind of software exists and has been put into actual use. However, it is in a strictly confidential stage. If someone is afraid of being deciphered and found a way to deal with it, it will not work."

Liu Pengcheng asked: "Are you from the beautiful country?"

Xiao Zhai: "This beautiful country is so safe, how can we need such a thing?"

Liu Pengcheng said to himself: wait until the golden autumn next year to see if you can still say this!

Xiao Zhai said: "It's from the Kingdom of David. They use this software to screen whether there are people with turbans and fireworks among the people entering 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? That's why I did this?"

Liu Pengcheng had no choice but to briefly explain the role and working methods of the picture detective to Xiao Zhai.

Xiao Zhai's eyes widened: "Brother Liu, why don't you tell me a science fiction story? With the resolution of the camera, how can it achieve what you said? It would be pretty good if it could show whether a person's head is a circle or not a square.

How is it possible to directly identify the identity? Even if there is a high-definition camera, what is the cost? Let’s not talk about other places, let’s just say how many can Yuhang afford?”

When he said this, Liu Pengcheng also woke up. This was the year 2000. This year, digital cameras had just entered the three-megapixel era! They were not able to shoot at night. This year, all mobile phones still had black and white screens, and occasionally a few models had blue light screens.

It’s all considered black technology!

Liu Pengcheng was still reflecting on his "great success", but Xiao Zhai said: "But I think with the development of technology, there will always be a day when your vision will be realized. Now it is difficult for us to screen others, but there is no problem in screening cars!"

Xiao Zhai suddenly opened the door to a new world and felt that he had made a very good software. He then dragged Liu Pengcheng back to his office to check out the few people who had caught motorcycles that often appeared near crime scenes.
