Chapter 121: Steed

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 be more likely to put down the eggs and leave.

"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 police officer 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, so 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 him.”

"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 chose a stupid method just because of their insufficient technical level and lack of ability to pick up girls.

Jiang Yuan was simple. He directly found a video that could expose the suspect's full face, then enhanced the whole video, and then watched it frame by frame, screened out more than a dozen frames of images, and then used image registration, then super-resolution fusion, and finally directly removed noise and blur.

It took only a quarter of an hour, using several softwares in the computer, and finally, on Photoshop, the suspect's facial expression gradually appeared.

The computer worked frantically for no more than 5 minutes.

The victim, the lady, clapped her hands happily and nodded repeatedly: "It's also played like this on TV, I said, they just said no."

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

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

This is especially true for those who work with images.

In recent years, image detection has become a popular subject. Image detectives with slightly better skills can really solve cases.

This kind of thing happened last time because the concept of DNA was not yet popular.

But even the image detection brigade of the provincial department was dumbfounded when they saw Jiang Yuan doing image enhancement during the fingerprint competition. At that time, Jiang Yuan still mastered the LV3 image enhancement skills.

In other words, LV3 image enhancement can beat the image detection of the provincial department. LV5 image enhancement... Jiang Yuan couldn't show his full form this time.

This is also because the skills required for image detection are too hardcore and too popular.

Hardcore means that it has high requirements for basic disciplines, which also requires high academic qualifications for related practitioners. With high academic qualifications, there are too many jobs to choose from, and they are good at taking exams. In this era where every job must be tested, even if you like the establishment, you may not necessarily choose to be a policeman.

On the other hand, if you want to make money, if you have mastered the industry's top-notch imaging technology, that is, the LV3 level, you can go to various Internet giants or professional companies and get a hundred times more rewards than the police.

Even if you want to devote yourself to criminal science and technology, it will be easier and more profitable to find a company that sells surveillance equipment. If you are stronger, it will 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 is changed to Changyang City or a larger city, the image detection brigade is not enough.

Even the image detection brigade based on the district has been popularized in many cities. But in the final analysis, with the increase in the number of surveillance, it is impossible to see it by human eyes. Whether it is data processing or identification, it requires technology to solve it.

In this environment, it is impossible for the image studio of Ningtai County Bureau to have a high-tech genius.

It's like everyone is a big animal, and the big animal in the field of image detection is equivalent to a horse.

Other professions that use donkeys, mules, and cows can produce some diligent, hardworking, and excellent players.

But it is not the case for the profession that uses horses. Those who run fast, look beautiful, have long legs, big breasts, long hair, hairless, fat buttocks... no matter which quality is outstanding, they will definitely be taken away from other places. Even if they are dwarfs, they can still be used as pet horses.

So, to put it in a better way, whether it is Zhuang Wei in his thirties or Gao Jiansheng in his twenties, they are all poor horses.

The state that the breed will not change as they age.

"Print it out?" Jiang Yuan, a long-legged horse of the competition level, finished the image and turned to ask a few people.

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

With a sound of "click", a photo of the suspect with a nose and eyes was printed out.

The clarity of the photo itself is average, and the printer is also poor, but the face of the person in it can still be clearly seen. If it is just for passing around, it should be enough.

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

The people in the imaging office looked at each other, and they had not yet woken up from the fact that they were big horses.

The lady who reported the case stood up, revealing a light yellow hip skirt and even whiter legs. She shouted enthusiastically: "Comrade police, can you add WeChat?"

"If you have any questions, just find 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 loosened her hand, the egg broke.
