civil forensic

Chapter 122 Horses
The victim was in his early thirties, sweet-looking, well-dressed, and half of his exposed arms were white, as if a carrot had been peeled.

Seeing her anxious expression, Jiang Yuan guessed that her case should not be too serious.

He has seen many victims now, and when it comes to the murder case, they all have expressions of sadness, numbness and despair, and punishing criminals is to restore sadness.

Instead, they looked at the very anxious victim, and the cases involved were often not too anxious for the criminal police.

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

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

"Oh, Forensic Doctor Jiang. I heard that you are back, so I was too busy to attend to it." There are three people in the imaging office, one more than the one who did the trace inspection, but they are all young people and wear myopia glasses.The one who spoke was the original four-eyed Zhuang Wei - when he came to the county bureau to report more than ten years ago, no one in the criminal police team wore glasses for a long time, so he liked to use the nickname "four-eyed".

Now, after so many years, Zhuang Wei is still a young man in the criminal police team, but the nickname of Four Eyes has been shaken to pieces and can no longer be exclusive.

"This trip involved a lot of murders. Master asked me to give some red eggs to the people on the first floor. The cigarettes were also padded with yellow paper and burnt." Jiang Yuan said while passing the cigarettes.

The three people in the imaging office came to pick it up. Two senior police officers picked up their cigarettes, and noticed that the lady next to them frowned, so they quickly put them away.

The youngest policeman, Gao Jiansheng with three generations and four eyes, lit a cigarette slowly instead.Although he is young, he is a local, married a long time ago, well-informed, and the least moved.

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 that the cigarettes are covered with yellow paper?" Seeing that the video was paused, the lady asked curiously, but it was useless to worry.

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

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

"Do you want to get a clearer picture of this person?" Jiang Yuan muttered and asked again.

In the coming days, if he wants to make videos conveniently, he still needs to establish a good relationship with his colleagues in the video office.

The first-generation four-eyed Zhuang Wei said "En", and said: "This man should be a habitual criminal. He is very skilled in stealing things and knows how to hide from the camera. We want to get a clearer picture and ask it at the nearby police station. , maybe someone knows it.”

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

Zhuang Wei nodded in agreement, and said with emotion: "It's about the same as the left-behind elderly in the countryside. The younger ones, who have the ability to learn, either engage in telecom fraud or quit the circle. The rest of them just don't want to. You can’t learn new things, you can’t make money, and you don’t want to look for a job seriously, and you don’t even want to go to a big city.”

"Normally, older people don't even like to travel, let alone go to other places to steal things." Gao Jiansheng, who has three generations and four eyes, now has life experience.

"I will do image enhancement, so I can enhance the image for you?" Jiang Yuan put out a few polite words, and directly stated his purpose.

The first four-eyed Zhuang Wei frowned slightly. He has been making images for more than ten years, and he has rarely been intruded into the professional field. So he looked at Jiang Yuan and asked, "Forensic doctors still study images?"

"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 make fingerprints, the efficiency and accuracy will be higher."

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

He wanted to see what the new forensic doctor Jiang Yuan, who had recently become famous, 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? Can I see the face clearly?"

"It's enough to recognize the face. We were all chasing after the clothes just now." In fact, following the monitoring and tracking is not an easy task.

The first point is that surveillance video has never been all-round without dead ends.Most art galleries and museums can't do that, let alone on the street.

Of course, certain streets in some cities might do it, and in such places, burglaries usually don't happen.

Secondly, when walking on the street, there must be shelters, sometimes it is tree branches, sometimes it is vehicles, sometimes there are too many people and the people being watched are too short.In addition to entering buildings and vehicles, it is still very hard to track them all the way through surveillance video.

Except for licking dogs of course!

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

For example, if it disappears in a blind spot, it may take an hour or two for the video police to find it.

It can be said that Zhuang Wei and others chose to follow the surveillance video, and then searched for high-definition cameras all the way to crop a suitable high-definition image. This way, rightly wrong, was a waste of manpower, time and energy.

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

But for Jiang Yuan, this process is completely unnecessary.

Zhuang Wei and the others chose a stupid method just because of their lack of technical level and lack of ability to pick up girls.

Jiang Yuan was simple. He directly found a video that could expose the entire face of the suspect, then enhanced the entire video, and then watched it frame by frame, screened out more than a dozen frames of images, and then used image registration, and then superimposed Resolution fusion, and finally denoising and deblurring directly.

That is to say, within a quarter of an hour, I used several softwares in the computer, and finally, on Photoshop, the facial expression of the suspect was gradually revealed.

The time of computer manic work does not exceed 5 minutes.

The lady who was the victim clapped her hands happily and nodded vigorously: "That's how it's played on TV, I'll just say, they just said no."

Zhuang Wei and the others next to him could already see that their mouths were full of fists.

There are stories in this kind of TV, but not in reality. It’s like watching the Dakar 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 even more true for videographers.

In recent years, Tucai has been a prominent study.A slightly better technique of graphic investigation can really solve the case if it is pulled out.

This kind of thing happened last time because the concept of DNA has not yet been popularized.

But even the Picture Investigation Team of the Provincial Department, when Jiang Yuan was participating in the fingerprint contest, watched him do image enhancement, and he looked dumbfounded.At that time, Jiang Yuan still mastered the image enhancement skills of LV3.

In other words, the image enhancement of LV3 can overwhelm the image detection of the provincial government. The image enhancement of LV5...Jiang Yuan couldn't show his full body this time.

This is also because the skills required for graphic reconnaissance are too hard-core and too popular.

Hard core means that it has high requirements for basic disciplines, which means it has high requirements for the academic qualifications of relevant practitioners.However, with a high degree of education, there are too many jobs to choose from, and you are good at exams. In this era when every entry must take an exam, even if you like the bureaucracy, you may not choose to be a policeman.

On the other hand, if you want to make money, if you have mastered the first-class video technology in the industry, that is, LV3 level, you can go to various Internet companies or professional companies, and you can get a hundred times the return of the police.

It is even said that if you must devote yourself to criminal science and technology, it will be easier and more profitable to find any company that sells surveillance equipment.If the strength is stronger, the significance of doing big data is even greater.In a small county like Ningtai, the main streets are not covered by surveillance, and only two cameras are needed to work. In Changyang City or a larger city, the large-scale image surveillance of the brigade is not enough.

Even district-based graphic investigation brigades have become popular in many cities.But in the final analysis, as the number of monitoring increases, it cannot be seen by human eyes. Whether it is data processing or identification, it needs technology to solve it.

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

It's as if everyone is a big animal. Tuzhen, a professional big animal, uses horses.

Other professionals who use donkeys, mules, and cattle can produce some diligent, hard-working, and outstanding players.

But it’s not enough to use horse majors. Those who run fast, those who are beautiful, those with long legs, those with big breasts, those with long hair, those who are hairless, those with fat buttocks... No matter which quality is outstanding, it will definitely be recognized by others. The place was pulled away.It is a dwarf type, and it can also be used as a pet horse.

So, to put it more bluntly, whether it is Zhuang Wei, who is in his 30s, or Gao Jiansheng, who is in his 20s, they are all idiots.

The state in which the breed does not change as the age increases.

"Print it out?" Competition-level long-legged Ma Jiangyuan finished the image and turned to ask a few 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 nose and eyes was printed out.

The clarity of the photo itself is average, and the printer is also stretched, but the faces in it can still be clearly seen. If it is only used 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 suckers.

The lady who reported the crime stood up, revealing a pale yellow skirt with wraparound hips and fairer legs. She shouted enthusiastically, "Comrade police, can you add a WeChat account?"

"You can just ask them if you have anything to do. I'm a forensic doctor." Jiang Yuan handed the lady a red egg and left.

The lady held the egg, and it took several seconds before she realized what the forensic doctor meant. When she let go, the egg broke.
