Chapter 169 Fascination
The thick man No. 50 or 60 stared at Jiang Yuan with burning eyes.
Jiang Yuan pushed up his flat mirror and continued.
Photoshop is a very interesting software.
The girls love it.
It has a wide range of applications, mainly because it has a high degree of freedom and is also very deep.
The story derived from this, from getting started to giving up, is a good description.
Of course, ordinary consumers generally only come into contact with the entertainment side of it, such as editing pictures, changing scenes, etc. If you make it for an afternoon, you can post it on Moments, and if you make it for half an afternoon, you can send it to your boss for hot searches.
Those who are willing to spend a night can usually graft the head of a star onto the head of other strange animals.
Or reshape a batch of wedding photos to make the bride and groom and their friends feel at ease as if they were attending someone else's wedding.
But on the flip side of entertainment, Photoshop can also be very cruel.
It can be used to cut out official seals. If used well, the sentence will be three years.
It can also be used to synthesize photos for blackmail. Hunan Shuangfeng has developed it into an industry, specifically targeting officials to commit crimes, with far-reaching influence.
Of course, it can also be used to solve crimes, making them infinitely more difficult to solve.
In the province-wide fingerprint battle, Jiang Yuan used LV4's Qingdao-style fingerprint analysis method, LV3's Chongqing-style fingerprint analysis method, and image enhancement skills to kill everyone.
The continuous solving of the backlog of murder cases actually means that Jiang Yuan's fingerprint identification skills have greatly exceeded the average level of provincial experts.
The fingerprints I encounter now are beyond the difficulty of normal difficult fingerprints.
"If you use Photoshop to process difficult fingerprints, you will often get surprises. Photoshop is PS. The key point of using it in our criminal investigation is to ensure the accuracy of the image, and there must be certain rules when modifying it."
Jiang Yuan was talking, but most of his energy was still focused on software operation.
Practical explanation, with actual combat at the front and explanation at the back.
Chen Wenming straightened his back, watched Jiang Yuan's operations for a while, and then slowly imitated Cao Keyang next to him, lying on his back.
If you look at some things in a different way, your emotions will be different and your sense of gain will be different.
Just like Cao Keyang, at the beginning, he straightened his back and looked very uncomfortable.
After lying down and watching, I felt much more comfortable.
Cao Keyang's suppressed emotions were released, and at some point, he even smiled gently.
"A group of people are enjoying watching it." Chen Wenming looked around and saw all the tracers lying flat on their backs. He couldn't help but sigh: The high-level technology has greatly reduced everyone's enthusiasm for learning.
When a trace inspector from the district bureau heard what Chen Wenming said, he didn't agree with it. He looked at the projection screen and said, "Team Chen, you have to look at it from another angle to find it interesting."
"What angle."
"For example, I never knew that fingerprint identification could reach this level. It's like a magical skill." The fingerprint examiner from the district bureau was only a little younger than Chen Wenming, and he spoke calmly.
Chen Wenming still shook his head and said: "Dragon-slaying skills."
The trace examiner beside him didn't care, and said: "As long as I'm handsome, that's it. From now on, if my nephew asks me what I do all day long, I'll always have something to brag about. I can't just be the awesome ones on TV every day. Reality means nothing. .”
Cao Keyang nodded. In his heart, he naturally expected to become such an appraisal expert, but such words were inappropriate to say in front of colleagues in the unit, especially junior superiors.
You can’t do it yourself, but it’s a pleasure to brag about your colleagues.
Jiang Yuan can also be regarded as their colleague.
Chen Wenming also knew how difficult it was to learn fingerprint identification skills of Jiang Yuan's level. PS skills were equally boring and required mathematics and other related knowledge in the later stages.
Therefore, Chen Wenming sighed: "I finally managed to get a half-day training together, and I can see how handsome he is."
"There are many opportunities for training, no, there are many opportunities for learning. This is called training." Another trace inspector joined the discussion in a low voice.
At the lecture, no one paid too much attention to the specific technical details.
If you don’t understand something in the first class, don’t think you can make it up in the second class.
However, everyone is still very interested in the methods and methods of high-level fingerprint identification and the extent to which they can be achieved.
So, at this moment, there were more people whispering in the audience, but also more people smiling.
When Chen Wenming saw that the trace inspectors around him were all against him, he had nothing to say.
In fact, telling the cutting-edge capabilities of a technology and discussing its boundaries is originally a training model.
For example, fingerprint technology is now capable of extracting it from clothes, bedsheets, etc. Then we need to inform the frontline police through various means. Otherwise, there will be no operation by the frontline police and only research done in the laboratory. , what’s the use.
Similarly, fingerprint collection training is conducted every year by units at all levels, in order to strengthen training and raise awareness at the grassroots level so that they can do better and more.
The frontier expansion of DNA is more obvious. In the early years, DNA testing could only be done on blood, saliva, human tissue and urine. Many places did not start to promote sweat until around 2008. In another 10 years, grassroots police updated their understanding that all places where the suspect has been in contact You can try it all.
Today's training, everyone originally came to learn about fingerprint identification, so the first class was disappointing.
However, by the second class, more and more people began to listen to it as a cutting-edge lecture, and it became very good.
After all, people who usually give cutting-edge lectures are often not cutting-edge.
What Jiang Yuan showed today, in the eyes of a group of trace policemen, was beautiful.
"Well, after processing like this, let's run again." Jiang Yuan was talking about the processed fingerprint image.
The one in the front row couldn't help but burst into laughter: "It doesn't look like anything at all."
"In fact, they are exactly the same pictures. This can be directly proved. If the suspect's lawyer raises this point, we can do a criminal investigation appraisal... Do you want to do it? It may take about ten minutes..." Jiang Yuan was polite. Yes, if anyone has an opinion, they will answer it carefully.
But the trace inspector in the front row waved his hand: "Don't worry about me, just follow your own syllabus."
Jiang Yuan actually didn't have a syllabus, but he wasn't particularly interested in the name of the trace inspector, so he said: "Then let me continue, well, now it's just a matter of marking the characteristic points again. This time, we still have to choose A smaller area…”
"My suggestion for which area to choose is based on the shape of your fingers."
"We have dug up two cases, and we have two sets of fingerprints for reference. From here, we can actually tell a little bit about his hand habits."
"Well, we can actually use some thinking about footprint identification here..."
Jiang Yuan mentioned it briefly but didn't say much. After all, today is a lecture on fingerprint identification, so it’s best to try not to go astray.
Chen Wenming sat up involuntarily.
When he usually does fingerprints, he actually uses the idea of footprints.
This is a natural choice. People have 10 fingers - normal people. In terms of use, there are always some habitual movements and different operating techniques, including whether you prefer to use your left hand or your right hand, and whether you prefer to use one finger or two fingers. , like the index finger, middle finger, middle finger and ring finger, etc.
But unlike the development of footprint identification, there are no norms and rules in the usage habits of fingerprints.
Everyone is figuring it out on their own.
Chen Wenming is also thinking about it, but there are not many opportunities to use it.
At this moment, he wanted to hear Jiang Yuan's side of the story.
Although the Dragon Slaying Technique is in a state where there is no dragon to kill, it must be very good to absorb the essence of the Dragon Slaying Technique and slaughter cattle and sheep.
However, Jiang Yuan did not continue talking about the fingerprint footprint thinking.
Because the characteristic points of the fingerprint have been marked, if you send it to the fingerprint database for running at this time, new results will come out soon.
"You can see that after processing like this, it will be easy to compare with the existing fingerprints, and the results will be easy to come out. Because it is an assignment system, after processing with PS, its assignment can obviously be improved..."
Jiang Yuan began to tell the main points.
The trace inspectors below were already anxious, and some even shouted: "Call first, call first!"
"We're dialing." Jiang Yuan took out his cell phone from under the table and said, "Don't worry, he's in prison."
After dialing the phone, Jiang Yuan reported the situation again, and the criminal police captain on the other side naturally thanked him happily again.
Even if the person is in jail, the case is considered solved.
Moreover, criminal suspects have to continue to be prosecuted and receive increased sentences, which saves time and energy in arresting them.
Jiang Yuan suggested continuing to dig into the case, and then hung up the phone.
The trace inspectors in the audience listened with fascination.
Especially the last part, it was like a dream.
A normal criminal police captain, when faced with a suggestion, would chew it up and spit it out together with the person making the suggestion.
Jiang Yuan was a little used to the politeness of the criminal police captains from other counties, but looking at everyone's expressions, he quickly changed to a more serious look and said: "Let's continue the class..."
Woo...
The phone vibrated again.
Jiang Yuan glanced at it and hurriedly explained: "It's a call from Miaohe County. I don't know if there is any unexpected situation. I'll answer it."
After speaking, Jiang Yuan answered the phone.
In the earphones, the voice of the Miaohe County Criminal Police Captain was deafening: "Jiang Yuan, thank you very much, the person has been caught."
"That's great, congratulations."
"Congratulations to us. This case was saved thanks to you."
"Did the suspect confess?"
"Not yet. It should be soon. We have found some evidence in his home. There is no problem with zero confession. It will only be a matter of time before he confesses." The captain of the Miaohe County Criminal Police Brigade greeted him and hung up the phone after a while.
Turning around, the room was full of traces, and their eyes were gleaming.
The long-lost passion arose again, and everyone fantasized about being the one making the call.
