I'm a Super Cop

6 p.m.

Office of the third criminal investigation group of Furong Branch.

Police officer Wang stood by the water dispenser, gulping and pouring a large cup of hot water. Then he patted his stomach and said, "I understand that after working in a mental hospital for a long time, people's spirit is extremely broken."

Seeing that Gu Chen had finished sorting out the case, officer Wang came over and patted Gu Chen on the shoulder: "Gu Chen, the case was handled well just now, and the efficiency is getting higher and higher."

"The main reason is that the former president Zou has already explained what should be explained, so the psychological defense line of these people It's not long before it's broken. " Gu Chen is as modest as ever.

Although this case, from the beginning to the end of the clues collection, are all in their own collation.

However, police officer Wang and Lu Weiwei also gave the necessary support, as well as the colleagues in the control room. All of them paid their own strength for this case.

"I'll say that the nurse is not very kind." Lu Weiwei ate her own potato chips and said, "I started to let her tell the truth. She didn't admit it at first. As a result, we put the facts to him and took the clues. She immediately said that it was director Liu and Director Zou who did it. She was only forced to do it. She didn't say it was her own greed from the beginning to the end."

"Who will say that they are satisfied when they find a shortcut to make money?" Officer Wang returned to his seat, took out the potato chips from Lu Weiwei's hand and threw them into his mouth. He said, "in the final analysis, greed is greed. Can you be coerced if you are not greedy? These two women are really not easy. "

Gu Chen pats Lu Weiwei on the shoulder with the collected information. After Lu Weiwei takes it, she passes it on to officer Wang.

In the afternoon, they took the four people back to the police station for relevant interrogation.

Due to the early explanation of President Zou, the other three people were unable to refute.

In the face of all kinds of facts and evidence, everyone pleaded guilty and the trial was very smooth.

Gu Chen took advantage of the evening meal, finishing all the data files.

From receiving the report in the afternoon to closing the case before dinner, the efficiency is high to flying.

Gu Chen feels more and more that he has made some progress in various skills.

However, compared with the previous excellent skills, perhaps the improvement of these abilities is not much different in the eyes of outsiders.

However, it is very practical to put it into the handling of cases.

"Brother Wang, do you think it's ok?" Asked Gu Chen.

Officer Wang looked through it, nodded and said, "yes, I can. I can rest assured that the case summary you have made will be written according to this standard."

"Ha ha." Lu Weiwei on one side held back a smile and said, "I said Lao Wang, someone else's Gu Chen just showed you some meaning. Are you serious? Do you still need to evaluate what Gu Chen summarized? Zhao Bureau has already taken him as a benchmark. "

"It's called learning from each other to make up for mistakes. If you don't understand, don't talk nonsense." Officer Wang waved his hand and stubbornly maintained his dignity.

Lu Weiwei looked down at her watch, touched her groaning stomach and said, "it's more than six o'clock. If you don't go to the canteen, you'll have to eat leftovers. It's estimated that master Nie will feed the food from the canteen to the husky later."

"Then hurry up, pack up, let's go to the canteen." At the moment, officer Wang realized that he was really hungry.

"You go first. I'll be right there." Gu Chen arranges the documents on his desk.

Lu Weiwei and Wang police officers looked at each other, and they nodded one after another.

"All right, Mr. Gu, let's cook the food for you first. Please remember to come to us." She said.

"No problem." Gu Chen smiles and speeds up sorting out the information on the table.

Not long after police officer Wang and Lu Weiwei left the office, Gu Chen had finished sorting out and was ready to go to the canteen.

In my mind, the beautiful mechanical female voice of the system came again.

"New achievement: the victim's heartfelt thanks."

"The victim's heartfelt thanks are the greatest praise to the police."

"Reward item: an intermediate treasure box."

"Please collect the reward items as soon as possible."

Gu Chen Leng for a moment, but soon found that in front of the visual interface, suddenly appeared a small treasure box.

"This is an intermediate treasure box. It's much better than the energy drink that the primary treasure box always gives out."

Thinking of this, Gu Chen looked around.

At the moment, in the empty three groups of offices, only myself sit here alone.

Gu Chen can't wait to pick it up and click open again.

Soon, the mechanical voice came back again.

"Acquiring face recognition skills (primary): face recognition skills mainly include face image acquisition and detection, face image preprocessing, face image feature extraction and matching and recognition."

"Face recognition?" Gu Chen was stunned for a moment. He said that this is the research direction of cutting-edge technology!

Can this system provide convenience?

We should know that these technologies may not be mature in the field of science and technology. If the system uses a set of immature skills as reward items, will it be perfunctory?"It sounds high-end, but are these skills reliable?" Gu Chen hesitated for a moment and asked, "you said that the face recognition skills include four sub skills. But what are the functions of these skills in practical use?"

Again, the voice of the woman's voice echoed in her mind.

"You have acquired face recognition skills (primary level), face image acquisition skills. For different face images, you can capture them with your binocular camera lens."

"Blessed binocular camera lens?" Gu Chen said he didn't understand.

"Yes, facial image acquisition skills can be used on the basis of the primary skills of visual clipping."

"I see." Gu Chen suddenly realized: "it is to use the primary skill of visual shearing to blink twice on the target to obtain the facial image acquisition skill in face recognition, right?"

"Yes, but you must first turn on face recognition to acquire face image acquisition skills."

The beautiful mechanical female voice is still very mechanical

"I understand." Gu Chen's reaction speed is still very fast, and he asked, "what are the targets?"

For example, the static images and expressions of different voices can be obtained

"When the other party is in the range of acquisition and shooting, the face image acquisition skill will automatically search and shoot the other person's face image."

"What about face detection?" Gu Chen asked again.

"Face detection: in practice, it is mainly used for the preprocessing of face recognition, that is to accurately calibrate the position and size of the face in the image."

"Face images contain rich pattern features, such as histogram features, color features, template features, structural features and Haar features."

"Face detection is to pick out the useful information and use these features to realize face detection."

"So it is." Gu Chen is still interested in such skills.

If a worker wants to do a good job, he must sharpen his tools first.

In order to use these skills well, the necessary knowledge is necessary.

Since face recognition skills include face image acquisition and detection.

But there are also face image preprocessing, face image feature extraction and matching and recognition must be understood.

The system seems to have mind reading skills. Gu Chen thinks that the system can quickly respond to it.

Without waiting for Gu Chen to ask, the beautiful mechanical female voice explained again:

"face image preprocessing: for the face image preprocessing, it is based on the results of face detection, processing the image and ultimately serving the process of feature extraction."

"The original image you get can't be used directly because of the limitation of various conditions and random interference. It must be preprocessed in the early stage of image processing, such as gray correction, noise filtering and so on."

"For the face image, the preprocessing process mainly includes light compensation, gray level transformation, histogram equalization, normalization, geometric correction, filtering and sharpening of the face image. Can you understand these?"

Gu Chen has a specialized memory, these data in his mind, soon can firmly remember.

"No problem. I remember 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 available for face recognition skills are usually divided into visual features, pixel statistical features, face image transform coefficient features, and face image algebraic features."

"Face feature extraction is the process of face feature extraction, also known as face representation. It is the process of feature modeling of face."

"Face feature extraction methods can be divided into two categories: one is based on knowledge, the other is based on algebraic features or statistical learning. Can you remember it?"

Gu Chen has already recorded where the mechanical female voice says.

Quickly nodded: "no problem, can remember."

"Very good. We'll move on to the next stage." After affirming Gu Chen's ability, the mechanical female voice continues to enter the lower stage of skill interpretation.

"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 face features to be recognized with the obtained face feature templates, and judge the identity information of the face according to the similarity degree."

"This process is divided into two categories: one is confirmation, which is one-to-one image comparison, and the other is identification, which is one-to-one image matching and comparison process. Do you understand?"

"Yes." Gu Chen was in a cold sweat.

The influx of a large amount of data, in Gu Chen's mind constantly digest, fusion, let Gu Chen feel that the new skills seem to be a bit powerful.Although we understand the basic theory, how to use it seems to be the biggest difficulty in front of us.

Face recognition technology has a wide range of skills. If it can be fully utilized, it seems that it can break the boundaries of science and technology and walk in the forefront of the times?

Gu Chen closed his eyes and let the skill data brew in his mind, so that he can digest and absorb faster and better.

Just then, Gu Chen's mobile phone on the table rings. It's Lu Weiwei.

"Hello, sister Lu!"

"Brother Gu, where are you? Why haven't you arrived yet? " Lu Weiwei on the other end of the phone is worried.

"I'm still in the office. I'll be right there." Gu Chen quickly looked at his watch and found that 15 minutes had passed.

"Are you still in the office?" Lu Weiwei at the other end of the phone said she was shocked and said: "I said Mr. Gu, people are iron and rice is steel. You can't learn from those old comrades. You can't eat regularly. If you have stomach trouble, I won't allow it."

After thinking about it, Lu Weiwei said again: "is the work in hand not finished yet? Why don't I bring your dinner back? "

"No, sister Lu. I'll be right here."

"Well, Lao Wang and I will wait for you in the dining room."

After a few jokes, the two hang up.

Gu Chen takes a deep breath, pulls out a paper towel from the table, soaks sweat on his forehead, and hugs the paper into a ball, and throws it into the trash can at the door with his shooting posture.

"Boom! Boom

At the moment, the window suddenly sounded thunder, the sky also gradually dim down.

Gu Chen found that the sky outside the window was constantly flashing.

All of a sudden, a dazzling electric light shone brightly on the sky and the earth.

Gu Chen even clearly saw the opposite building, even the iron tripod on the opposite building, the network base station boxes of China Mobile Unicom and China Telecom, respectively deployed in different directions.

"Can't the mobile base station box be damaged by thunder? Otherwise, the 4G network How could it be so slow? "

think that it should not be a road paving for 5g, intentionally decreasing net speed. The latest network speed of mobile network can be called tortoise speed. Gu Chen can not help but make complaints about it.

The thunder did not stop, and there was another flash of lightning. The heavy rain was like a broken bead, falling continuously.

The rain from the eaves converged into streams in the street.

The whole day was dark, as if it was going to collapse. It was estimated that Wu Dalang could not hold it.

Wind chasing rain, rain driving wind, wind and rain together to catch up with the dark clouds in the sky, the whole world is in the rain.

There are few pedestrians in the street

Gu Chen picked up the coat of police uniform hanging on the seat and put it on.

Then in the office, took down three umbrellas, ready to run in the direction of the canteen desperately.

But downstairs, two men in casual clothes quickly attracted Gu Chen's attention.

They each carry a suitcase, but still stand there, looking to wait for the rain to stop.

Seeing Gu Chen also looking at himself, the two men just smile and nod, which can be regarded as a greeting.

"Are you two here to do business?" Gu Chen suddenly asked.

Since the personnel list of Furong Branch Bureau has been determined for a long time, Gu Chen has a general understanding of all the new and old colleagues on the list.

But these two people, completely not in the Furong Branch of the police list, Gu Chen naturally very face-to-face.

"Yes, we come to Furong Branch office." One of them, a tall and thin man with dark skin, took the lead in answering in Mandarin with a Cantonese accent.

"Are you a stranger?" Gu Chen asked him with a smile.

"Yes, we are from Pengcheng. This time we come to Jiangnan City to handle some business."

Looking back at the office building, the man of medium stature laughed and said, "maybe we are late. Furong Branch Office has already finished work."

"Are you police, too?" Gu Chen asked again.

"Yes, we are all Pengcheng police. This time we are in Jiangnan City for a business trip." Said the tall, thin man.

"Welcome to Jiangnan City." Gu Chen took the initiative to come forward and shake hands with the two: "I am Gu Chen from the third criminal investigation group of Furong sub Bureau in Jiangnan City."

"My name is Gao Xu." The tall and thin man laughed and pointed to the man of medium stature beside him and said, "his name is Liao Kai. I am a partner."

"Welcome. Have you had dinner yet?" Asked Gu Chen.

They laughed and then shook their heads.

Gao Xu said: "just came here, suddenly it rained heavily, watching many people run to the canteen, but we didn't bring umbrella."

"Then you are lucky." Gu Chen gave Gao Xu and Liao Kai the umbrellas that were supposed to give to Lu Weiwei and officer Wang respectively: "take it, one for each."

"So lucky?" Liao Kai said with a smile, "thank you, Gu Chen."

"Don't mention it. I'm just going to the canteen. Let's go together."Before long, Gu Chen, Gao Xu and Liao Kai shake umbrellas at the door of the canteen.

Lu Weiwei found Gu Chen from afar. She waved to Gu Chen and said, "brother Gu, come quickly. The food is getting cold."

"Just come." Gu Chen, with Gao Xu and Liao Kai, first came to the side of police officer Wang and Lu Weiwei and said, "elder martial brother Wang, senior sister Lu, this is a colleague from Pengcheng. Come to our Furong police station for a business trip."

"Hello, my name is Gao Xu."

"My name is Liao Kai."

Both of them didn't seem to like talking, so they took the initiative to shake hands with police officer Wang and Lu Weiwei.

"My name is Lu Weiwei. He You can call him Lao Wang. We and Gu Chen belong to the third criminal investigation group. " Lu Weiwei has contracted all the right to speak.

"You haven't eaten yet, have you?" Officer Wang quickly stood up and said, "I'll get you two meals, or master Nie of the canteen will certainly take it to feed husky."

Officer Wang finished and left.

Not long after, they will be two dishes, on the table, a few people sit together to chat a few words.

"Where are you staying tonight?" Gu Chen takes out the napkin handed by Lu Weiwei and touches the corner of his mouth.

"I'm not sure. I'll find a hotel nearby and stay first." Gao Xu said.

Gu Chen said with a smile: "no, part of the police dormitory in Furong Branch is specially used for accommodating brother units when they are on business. You will stay in the police dormitory tonight."

"Yes." Lu Weiwei also said: "although there is no hotel outside, the hotel is comfortable, but there is an atmosphere. All the people who live there are policemen. We can talk about things and play cards. It's not boring."

Gao Xu and Liao Kai looked at each other and nodded.

"That's all right. It's up to you." Gao Xu said with a smile.

Officer Wang waved his hand: "it's all my brothers. What's your courtesy? Aren't you here for business? Stay here today, and tomorrow I'll take you to find the relevant docking. "

After thinking about it, officer Wang suddenly asked, "Oh, by the way, I don't know what you're doing in Jiangnan City this time."

Gao Xu said with a smile: "looking for abducted children."
