National Forensic Doctor

The victim was in his early thirties, sweet-looking, and well-dressed. The exposed half of his arm was white, like a peeled radish. Google search reading

Seeing her anxious expression, Jiang Yuan guessed that her condition was not too heavy.

He has seen many victims now. When they are about to die, they all have expressions of sadness, numbness and despair. Punishing criminals is all about reversing the sadness.

On the contrary, looking at the anxious victim, the crimes involved are often things that the criminal police are not too anxious about.

Of course, the two imaging colleagues in front of him looked very anxious. If it weren't for the new skills, Jiang Yuan would have put down the eggs and left.

"Eat a red egg and smoke a cigarette." Jiang Yuan stepped forward with a smile and handed out the basket.

"Oh, Medical Examiner Jiang. I heard that you are back, but I was too busy to take care of it." There are three people in the imaging office, one more than the one doing the trace examination, but they are all young people wearing glasses for myopia. The speaker was Zhuang Wei, the first generation of Four Eyes. When he came to the county bureau to report more than ten years ago, there was no one in the criminal police team who wore glasses for a long time, so he liked to use the nickname Four Eyes.

Now, after all these years, Zhuang Wei is still a young man in the criminal police team, but his nickname of "Four Eyes" has been shattered into pieces and is no longer exclusive to him.

"A lot of lives were involved when we went out this time. Master asked me to give some red eggs to everyone on the first floor. The cigarettes were also padded with yellow paper and burned." Jiang Yuan said while passing the cigarettes.

Three people from the imaging office came to pick it up. Two senior police officers took out cigarettes and noticed the lady next to them frowning, so they quickly put them away.

The youngest policeman, Gao Jiansheng, a third-generation policeman with four eyes, slowly lit up a cigarette. Although he is young, he is a local, has been married for a long time, is well-informed, and is the least impressed.

It's not like two old bachelors in the office who dare not even smoke a cigarette when they see a beautiful woman of about the same age.

"What does it mean to put a yellow paper on the cigarette?" The lady saw that the video was paused. There was no point in being anxious. Instead, she asked curiously.

"Just roll the cigarette on the yellow paper." Jiang Yuan took out the cigarette box, put it on the table, turned it over, and then rolled it over.

The lady understands a little bit, but also doesn’t understand a little bit.

"You want to get a clearer image of this person?" Jiang Yuan asked again, coquettishly.

In the coming days, if he wants to be able to do imaging conveniently, he still needs to establish a good relationship with his colleagues in the imaging office.

Zhuang Wei, the first generation of Four Eyes, said "En" and said: "This person should be a habitual criminal. He is very skilled in stealing things and knows how to hide from cameras. We want to get a clearer picture and take it to the nearby police station to ask. , maybe someone will know you."

"There are not many thieves still stealing things on the streets now." Jiang Yuan commented.

Zhuang Wei nodded in agreement and said with emotion: "They are similar to the left-behind elderly people in rural areas. The younger ones, those who have the ability to learn, have either committed telecom fraud or have withdrawn from the industry. The remaining ones are just unwilling I can’t learn new things, I can’t make money, and I don’t want to seriously look for a job, and I don’t even want to go to a big city.”

"It's normal. Older people don't even like to travel, let alone go to other places to steal things." Gao Jiansheng, the third generation and four eyes, now has life experience.

"I can do image enhancement to enhance the image for you?" Jiang Yuan said a few polite words and directly stated the purpose.

Zhuang Wei, the first generation of Four Eyes, frowned slightly. He had been doing imaging for more than ten years, and he was rarely intruded into the professional field. So he looked at Jiang Yuan and asked: "Forensic medicine still studies imaging?"

"I learned it by the way when I was doing fingerprints before." Jiang Yuan said the trick without hesitation: "Use image enhancement technology to process fingerprint images, and then do fingerprints. The efficiency and accuracy will be higher."

"Really..." Zhuang Wei said, giving up his seat in front of the computer.

He wanted to see what Jiang Yuan, a new forensic doctor who had become famous recently, wanted to do.

Jiang Yuan sat on it without hesitation, looked at the surveillance video in front of him, and asked, "Can any image be used? As long as you can see the face clearly?"

"As long as you can recognize the person's face. We just followed the clothes." In fact, following the surveillance is not very simple.

The first point is that surveillance video is never comprehensive. This is not possible in most art galleries and museums, let alone on the street.

Of course, this may be possible on certain streets in certain cities, and in such places thefts usually do not occur.

Secondly, when walking on the street, there must be shelter, sometimes it is branches, sometimes it is vehicles, sometimes there are too many people and the person being stared at is too short. In addition, it is very difficult to track all the way into buildings and vehicles through surveillance video.

Of course, except for dog licking!

This also takes into account the conscious defense of the person being followed.

For example, if a person disappears in a blind spot, it may take the imaging police one or two hours to search for it.

It can be said that Zhuang Wei and others chose to follow the surveillance video and then search for high-definition cameras along the way to crop the appropriate high-definition images. This approach, rightly or wrongly, is a waste of manpower, time and energy.

Many people have lost their mobile phones and go to the police station to report the incident, always thinking that they can find it by looking at the surveillance video. In many cases, they often overestimate the strength of the police who handle the incident, as well as the patience and determination to handle the incident.

For Jiang Yuan, this process is completely unnecessary.

Zhuang Wei and others just chose a stupid method because of their insufficient technical skills and insufficient ability to pick up girls.

Jiang Yuan found it simple. He directly found a video that could expose the suspect's full face, then enhanced the entire video, then watched it frame by frame, filtered out a dozen frames, then used image registration, and then super Resolution fusion, and finally direct denoising and model removal.

In just a quarter of an hour, using a few software on the computer, and finally using Photoshop, the suspect's face and expression were gradually revealed.

The time spent working frantically on the computer does not exceed 5 minutes.

The woman who was the victim clapped her hands happily and nodded her head: "It's the same on TV. I'm just telling you, they said no just now."

Zhuang Wei and the others next to him had already had their fists in their mouths.

This kind of story is on TV but not in reality. It’s like watching the Dhaka Rally. You know how they drive, but what does this have to do with your daily driving? Is your car good enough? Or is your technique good enough, or is your co-pilot good enough?

This is especially true for those who work on images.

In recent years, picture scouting has become very popular. A slightly better picture detective can really break it out by pulling it out.

The last time this kind of thing happened was because the concept of DNA had not yet become popular.

But even the provincial department's photo investigation team looked dumbfounded when Jiang Yuan was doing image enhancement while he was participating in the fingerprint competition. At that time, Jiang Yuan still mastered the LV3 image enhancement skill.

In other words, LV3's image enhancement can beat the provincial image detective. LV5's image enhancement...Jiang Yuan couldn't even show his complete body this time.

This is also because the skills required by picture scouts are too hard-core and too popular.

Hard core means that it has high requirements for basic subjects, and also has high academic requirements for relevant practitioners. With a high degree of education, there are too many jobs to choose from, and you are good at taking exams. In this era where everyone must take exams to get a job, even if you like the establishment, you may not choose to be a police officer.

On the other hand, if you want to make money and master the industry's first-class imaging technology, that is, at the LV3 level, you can go to various major Internet companies or professional companies, and you can get a hundred times more rewards than the police.

It is even said that if you really want to devote yourself to criminal science and technology, it will be easier and more profitable to find any company that sells surveillance equipment. If it were stronger, it would be more meaningful to do big data. In a small county like Ningtai, the main streets are not covered by surveillance, and only two images are needed to work. If it were Changyang City or a larger city, a large-scale picture detective would not be enough.

Even district-based reconnaissance brigades have been established in many cities. But in the final analysis, as the number of surveillance increases, it is impossible to see it with the human eye. Whether it is data processing or identification, technology is needed to solve it.

In this environment, it is impossible for the imaging studio of Ningtai County Bureau to have high-level talents.

It's like everyone is a big animal. The professional big animal of the picture scout is equivalent to a horse.

Other professionals who use donkeys, mules, and oxen can all produce players who are diligent, hardworking, and have excellent qualities in all aspects.

But it’s not enough to use the horse’s specialty. The one that runs fast, the one that is beautiful, the one with long legs, the one with big breasts, the one with long hair, the one with no hair, the one with fat butt... No matter which quality is outstanding, it will definitely be judged by others. The place was taken away. It's a dwarf type and can be used as a pet horse.

Therefore, to put it in a nicer way, both Zhuang Wei, who is in his thirties, and Gao Jiansheng, who is in his twenties, are both fools.

As age increases, the breed will not change.

"Print it out?" Ma Jiangyuan, a competition-level long-legged man, prepared the image and turned to ask several people.

"Oh, okay, print it out." Zhuang Wei was still a little dazed.

There was a sound of Gadada, and a photo of the suspect with a nose and eyes was printed.

The clarity of the photo itself is average, and the printer is too stretched, but the faces in it can still be clearly seen. If it is just for viewing, it should be enough.

Jiang Yuan picked up the remaining eggs, said, "I have to go to another office," and went to work.

Several people in the imaging office looked at each other, but they still hadn't woken up from the fact that they were big bastards.

The lady who reported the case stood up, revealing her light yellow hip skirt and whiter legs. She shouted with enthusiasm: "Comrade police, can you add me on WeChat?"

"If you have any questions, just come to them. I'm a forensic doctor." Jiang Yuan handed the lady a red egg and left.

The lady held the egg for several seconds before she realized what the forensic doctor meant. When she let go, the egg shattered.
