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 like it very much.
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 are generally only exposed to 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 so that the bride and groom and their friends feel at ease as if they are 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 you use it well, your prison sentence will be three years.
It can also be used to synthesize photos for extortion. 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 it infinitely more difficult.
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 and changed into a lying posture.
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 softly.
"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.
A trace inspection officer from the district bureau heard Chen Wenming's words and 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.
Even if you can't do it yourself, it's a pleasure to brag about your colleagues.
Jiang Yuan can also be regarded as their colleague.
Chen Wenming also knows how difficult it is to learn fingerprint identification skills of Jiang Yuan's level. PS skills are also boring and require mathematics and other related knowledge in the later stage.
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.
During the lecture, no one paid 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 extent to which advanced fingerprint identification methods can be achieved.
So, now, there are more people whispering and whispering in the audience, but everyone's smiles are also increasing.
When Chen Wenming saw that the trace inspectors around him were all opposed to 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, sheets and other places. Then we need to inform the frontline police through various means. Otherwise, there will be no operation by the frontline police and they will just conduct research 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 even more obvious. In the early years, DNA identification could only be done on blood, saliva, human tissue and urine. It was only around 2008 that many places began to promote sweat. In another 10 years, the updated understanding of grassroots police is
Any place where the suspect has been in contact can be tried.
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 police officers, was considered 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 the same 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 puts forward 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 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. Today is a lecture on fingerprint identification after all, so it's better not to go astray.
Chen Wenming sat up involuntarily.
When he usually does fingerprints, he actually uses the thinking 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.
, do you prefer the index finger, the middle finger, the middle finger, the 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 go on to talk about the footprint thinking of fingerprints.
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.
"Everyone can see that after processing like this, it will be easy to compare with the existing fingerprints, and the result will be easily obtained. Because it is an assignment system, after processing with PS, its assignment can obviously be improved..."
Jiang Yuan began to talk about 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, I'm in jail."
After dialing the phone, Jiang Yuan reported the situation again, and the captain of the criminal police team opposite 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 to continue digging into the case, and then hung up the phone.
The trace inspectors in the audience listened with fascination.
Especially the last part is 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 seeing 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 arrested."
"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 shining.
The long-lost passion arose again, and everyone dreamed of being the one making the call.
