Furong Branch Criminal Investigation Group Three Office.
Officer Wang stood next to the water dispenser and drank a large cup of hot water. Then he patted his stomach and said with satisfaction: "I finally understand that after working in a mental hospital for a long time, a person's spirit will be extremely broken."
After seeing that Gu Chen had sorted out the case, Officer Wang came over and patted Gu Chen on the shoulder: "Gu Chen, the case just now was handled well. The efficiency is getting higher and higher."
"The main reason is that Dean Zou has already explained everything that needs to be explained, so the psychological defenses of these people... were quickly broken, and it took no effort." Gu Chen was as humble as ever.
Although this case, from beginning to end, I collected clues all by myself.
However, Officer Wang and Lu Weiwei also provided necessary support, as well as colleagues in the dispatch room. Everyone contributed their own efforts to this case.
"I just said that this female nurse has no good intentions." Lu Weiwei said while eating her potato chips: "I started to ask her to tell the truth, but she refused to admit it at first. Then we told her the facts and got clues, and she immediately said it was Liu
What the director and Dean Zou did, he was just forced to do it, and he never said it was his own greed from beginning to end."
"Who would say they are satisfied after discovering a shortcut to make money?" Officer Wang returned to his seat, took the potato chips from Lu Weiwei's hand and threw them into his mouth, tutting: "In the final analysis, it is greed, not
Can greed be coerced? They even imprisoned patients with these people. These two women are really not simple."
Gu Chen patted Lu Weiwei's shoulder on the compiled information. Lu Weiwei took it and passed it to Officer Wang.
After everyone took the four people back to the police station in the afternoon, they conducted relevant interrogations.
Due to Dean Zou's explanation in advance, the other three were unable to refute.
In the face of various facts and evidence, everyone confessed, and the trial can be said to have gone very smoothly.
Gu Chen took advantage of the opportunity before dinner to finish organizing all the information files.
From receiving the report in the afternoon to closing the case before dinner, the efficiency was so high that it was so fast.
Gu Chen felt more and more that he had made some slight progress in various skills.
However, compared to the previous excellent skills, perhaps these improvements in abilities are not much different in the eyes of outsiders.
But when it comes to handling cases, it becomes very practical.
"Senior Brother Wang, do you think it's okay?" Gu Chen asked.
Officer Wang flipped through it briefly, nodded and said, "Okay, I can trust the file you made. Future case summaries will be written according to this standard."
"Haha." Lu Weiwei on the side said with a suppressed laugh: "Speaking of Lao Wang, Gu Chen just showed it to you for fun, but do you still take it seriously? Do you still need to evaluate what Gu Chen summarized? Director Zhao has already used him
It sets a benchmark.”
"This is called learning from each other and making up for mistakes. If you don't understand, don't talk nonsense." Officer Wang waved his hands and stubbornly maintained his dignity.
Lu Weiwei lowered her head to look at her watch, touched her growling stomach and said, "It's already past six o'clock. If you don't go to the cafeteria, you'll have to eat leftovers. I guess Master Nie will feed him food from the cafeteria later."
That husky.”
"Then hurry up, pack your things, and let's go to the cafeteria quickly." Only then did Officer Wang realize that he was really hungry.
"You go first, I'll be there soon." Gu Chen casually arranged the documents on his desk.
Lu Weiwei and Officer Wang looked at each other and nodded one after another.
"Okay, Junior Brother Gu, let's prepare the food for you first. Remember to come to us," Lu Weiwei said.
"No problem." Gu Chen smiled and quickly organized the information on the table.
Not long after Officer Wang and Lu Weiwei left the office, Gu Chen had finished tidying up and was about to get up and go to the canteen.
In my mind, the beautiful mechanical female voice of the system came again.
“New Achievement: Heartfelt Gratitude from Victims.”
"The victim's heartfelt gratitude is the greatest compliment to the police."
"Reward item: An intermediate treasure box."
"Please collect the reward items as soon as possible."
Gu Chen was stunned for a moment, but soon discovered that a small treasure box suddenly appeared in the visual interface in front of him.
"This is an intermediate treasure box. It's much better than the energy drinks that always pop out of the primary treasure box."
Thinking of this, Gu Chen looked around.
At this moment, in the empty offices of the third group, I was the only one sitting here alone.
Gu Chen couldn't wait to click to receive it, and clicked to open it again.
Soon, the mechanical female voice replied again.
"Acquire face recognition skills (elementary): Face recognition skills mainly include face image collection and detection, face image preprocessing, face image feature extraction, and matching and recognition."
"Face recognition?" Gu Chen was stunned for a moment, thinking that this is the direction that cutting-edge technology has been researching!
Can the system also provide convenience in this regard?
You know, these technologies may not be mature in the field of science and technology. Wouldn’t it be a bit perfunctory for the system to use a set of immature skills as reward items?
"It sounds quite high-end, but are these skills reliable?" Gu Chen hesitated and asked: "You said that this face recognition skill includes four sub-skills, but what are these skills in actual use?
Does it work?"
As soon as he finished speaking, the beautiful mechanical female voice echoed in his mind again.
"You have acquired face recognition skills (elementary level) and face image collection skills. Different face images can be collected through your blessed binocular camera lenses."
"Blessed double-eye camera lens?!" Gu Chen said he didn't understand.
"Yes, you can use face image collection skills on the basis of the basic skills of visual cutting."
"I understand." Gu Chen suddenly understood and said: "You can use the basic skill of visual shearing and blink twice at the identified target to obtain the face image collection skill in face recognition, right?"
"Yes, but you must first turn on face recognition and face image collection skills to obtain it."
The beautiful mechanical female voice is still very mechanical...
This chapter is not over yet, please click on the next page to continue reading! "Understood." Gu Chen responded quickly and asked again: "What are the targets?"
The mechanical female voice replied: "For example, static images, dynamic images, different positions, different expressions, etc. can all be well collected."
"When the other party is within the collection and shooting range, the face image collection skill will automatically search and capture the other party's face image."
"What about face detection?" Gu Chen asked again.
"Face detection: In practice, it is mainly used for preprocessing of face recognition, that is, to accurately calibrate the position and size of the face in the image."
"The pattern features contained in the face image are very rich, such as histogram features, color features, template features, structural features and Haar features, etc."
"Face detection is to pick out the useful information and use these features to achieve face detection."
"So that's it." Gu Chen was still quite interested in such skills.
If a worker wants to do his job well, he must first sharpen his tools.
To make good use of these skills, necessary understanding is still necessary.
Since face recognition skills include face image collection and detection.
But there is also facial image preprocessing, facial image feature extraction, matching and recognition that must be understood.
The system seems to have the ability to read minds. Whatever Gu Chen is thinking, the system can quickly respond.
Before Gu Chen could ask, the beautiful mechanical female voice explained again:
"Face image preprocessing: Face image preprocessing is a process that processes the image based on the face detection results and ultimately serves for feature extraction."
"The original image you obtain cannot often be used directly due to various conditions and random interference. It must be subjected to grayscale correction, noise filtering and other image preprocessing in the early stages of image processing."
"For face images, the preprocessing process mainly includes light compensation, grayscale transformation, histogram equalization, normalization, geometric correction, filtering and sharpening of face images, etc. Do you understand these?"
Gu Chen has an expert-level memory, and he can quickly remember these data in his mind.
"No problem, I've already remembered it." Gu Chen said.
"Very good." The mechanical female voice affirmed Gu Chen, and then came to the next stage.
"Face image feature extraction: The features that can be used in face recognition skills are usually divided into visual features, pixel statistical features, face image transformation coefficient features, face image algebra features, etc."
"Facial feature extraction is performed on certain features of the face. Facial feature extraction, also called face representation, is the process of feature modeling of the face."
"Facial feature extraction methods can be summarized into two categories: one is a representation method based on knowledge, and the other is a representation method based on algebraic features or statistical learning. Can you remember it?"
Whatever the mechanical female voice said, Gu Chen already remembered it.
He nodded quickly: "No problem, I can remember it."
"Very good, let's move on to the next stage." After confirming Gu Chen's ability, the mechanical female voice continued to explain the skills of the lower stage.
"Face image matching and recognition: The extracted feature data of the face image is searched and matched with the feature template stored in the database. By setting a threshold, when the similarity exceeds this threshold, the matching result is output.
"
"Face recognition is to compare the facial features to be recognized with the facial feature templates that have been obtained, and judge the identity information of the face based on the degree of similarity."
"This process is divided into two categories: one is confirmation, which is a one-to-one image comparison process, and the other is identification, which is a one-to-many image matching and comparison process. Do you understand?"
"Understood." Gu Chen was already breaking out in a cold sweat.
The influx of large amounts of data was continuously digested and integrated in Gu Chen's mind, making Gu Chen feel that the new skills seemed a bit powerful.
Although I understand the basic theory, how to apply it seems to be the biggest difficulty facing me.
Facial recognition technology covers a wide range of skills. If it can be fully utilized, it seems that it can break the boundaries of technology and be at the forefront of the times?
Gu Chen closed his eyes and let these skill data brew in his mind so that he could digest and absorb them faster and better.
At this moment, Gu Chen's cell phone on the table rang. It was Lu Weiwei calling.
"Hey, Senior Sister Lu!"
"Junior Brother Gu, where are you? Why haven't you arrived yet?" Lu Weiwei on the other end of the phone was a little anxious.
"I'm still in the office, I'll be here soon." Gu Chen quickly looked at his watch and realized that fifteen minutes had passed.
"Are you still in the office?" Lu Weiwei on the other end of the phone expressed shock and said: "Junior Brother Gu, people are like iron rice and steel. Don't be like those old comrades who eat irregularly. I won't agree if you get stomach trouble.
."
After thinking for a while, Lu Weiwei said again: "Is the work at hand not finished yet? How about I bring dinner back for you?"
"No need, Senior Sister Lu, I'll be right over now."
"Okay, Lao Wang and I are waiting for you in the cafeteria."
After a few words of banter, the two hung up the phone.
Gu Chen took a deep breath, took out a paper towel from the table, put the sweat on his forehead, crumpled the paper into a ball, and accurately threw it into the trash can at the door with a shooting posture.
"Boom! Boom!"
At this moment, thunder suddenly sounded outside the window, and the sky gradually darkened.
Only then did Gu Chen realize that the sky outside the window was constantly flashing.
Suddenly, a dazzling electric light illuminated the sky and the earth.
Gu Chen even clearly saw the building opposite, even the iron tripod on the building opposite, and the network base station boxes of China Mobile, China Unicom and China Telecom, which were deployed in different directions.
"Could it be that the mobile base station box was struck by lightning? Otherwise, how could this 4G network... be so ridiculously slow?"
Thinking about it, it is not likely that the network speed was deliberately lowered to pave the way for 5G. However, the recent network speed of the mobile network has been described as slow, and Gu Chen couldn't help but complain.
Before the thunder stopped, there was another bolt of lightning, and the heavy rain continued to fall like broken beads.
The rainwater flowing down from the eaves collected into streams on the street.
The whole sky was dark and heavy, as if it was about to collapse, and Wu Dalang probably couldn't withstand it.
The wind chases the rain, and the rain chases the wind. The wind and the rain join forces to chase the dark clouds in the sky, and the whole world is covered in rain.
There are very few pedestrians on the street...
Gu Chen picked up the police uniform jacket hanging on the seat and put it on.
Then in the office, he took down three umbrellas and prepared to run towards the cafeteria.
But downstairs from the office, two men in casual clothes quickly caught Gu Chen's attention.
The two of them each carried a suitcase, but they still stood there, looking like they were waiting for the rain to stop.
Seeing Gu Chen looking at them, the two men just smiled and nodded, which was regarded as saying hello.
"Are you two here for business?" Gu Chen suddenly asked.
Since the staff list of Furong Branch had already been determined, Gu Chen was on the list and had a general understanding of all his old and new colleagues.
But these two people were not on the list of police officers in Furong Branch at all, so Gu Chen was naturally very unfamiliar with them.
"Yes, we are here to handle business at Furong Branch." One of the men, a tall and thin man with dark skin, took the lead in answering in Mandarin with a southern Cantonese accent.
"Are you from outside?" Gu Chen asked him with a smile.
The two looked at each other, and another man of medium build also said: "Yes, we are from Pengcheng. This time we came to Jiangnan City specifically to handle some work."
Looking back at the office building, the man of medium build smiled and said: "Maybe we are late, the Furong branch has already closed."
"Are you also a policeman?" Gu Chen asked again.
"Yes, we are all Pengcheng police officers. We are here in Jiangnan City on official business this time," the tall and thin man said.
"Welcome to Jiangnan City." Gu Chen took the initiative to come forward, shook hands with the two of them and exchanged greetings: "I am Gu Chen from the Criminal Investigation Group Three of the Furong Branch of Jiangnan City."
"My name is Gao Xu." The tall and thin man smiled, pointed at the medium-sized man next to him and said, "His name is Liao Kai, and we are partners."
"Welcome, have you had dinner?" Gu Chen asked.
The two smiled and then shook their heads.
Gao Xu said: "When I first came here, it suddenly started raining heavily. I saw many people running to the cafeteria, but we didn't bring umbrellas."
"Then you're in luck." Gu Chen handed the umbrellas originally intended for Lu Weiwei and Officer Wang to Gao Xu and Liao Kai respectively: "Take it, one each."
"It seems you are really lucky?" Liao Kai smiled and said, "Thank you then, Gu Chen."
"You're welcome, I happen to be going to the cafeteria too, let's go there together."
Not long after, Gu Chen, Gao Xu and Liao Kai were shaking their umbrellas at the door of the cafeteria.
Lu Weiwei spotted Gu Chen from afar and waved to Gu Chen: "Junior Brother Gu, come quickly, the food is almost cold."
"Come here." Gu Chen, with Gao Xu and Liao Kai, first came to Police Officer Wang and Lu Weiwei and introduced: "Senior Brother Wang and Senior Sister Lu, these are colleagues from Pengcheng who are here on official business at our Furong Branch."
"Hello, my name is Gao Xu."
"My name is Liao Kai."
Neither of them seemed to like talking very much, so they took the initiative to step forward and shake hands with Officer Wang and Lu Weiwei.
"My name is Lu Weiwei, he... you can just call him Lao Wang, Gu Chen and we are both from the Criminal Investigation Group Three." Lu Weiwei took over all the rights to speak.
"You haven't eaten yet?" Officer Wang quickly stood up and said, "I'm going to get you two meals, otherwise Master Nie in the cafeteria will definitely have to carry them to feed the huskies."
Officer Wang left after finishing speaking.
Not long after, two dinner plates were placed on the dining table, and several people sat together and chatted for a while.
"Where are you staying tonight?" Gu Chen took out the napkin handed by Lu Weiwei and dipped it in the corner of his mouth.
"It's not decided yet. Let's find a hotel nearby to stay in later." Gao Xu said.
Gu Chen smiled and said: "No, part of the police dormitory in our Furong Branch is specially used to accommodate our brothers when they are on official business. You will stay in the police dormitory tonight."
"Yes." Lu Weiwei also said: "Although it is not as comfortable as staying in a hotel outside, it has an atmosphere. All the people living there are police officers. Everyone can chat and play cards when they have nothing to do, so it is not boring.
ah."
Gao Xu and Liao Kai looked at each other, then nodded.
"That's alright, I'll help you a lot." Gao Xu said with a smile.
Police Officer Wang waved his hand: "We are all brothers, why are you so polite? Aren't you here to do something? Stay here today, and I will take you to find relevant connections tomorrow."
After thinking about it, Officer Wang suddenly asked again: "Oh, by the way, I don't know what the main purpose of your visit to Jiangnan City is this time?"
Gao Xu smiled and said: "Looking for abducted children."
