Chapter 170
The five NO.60 thick man stared at Jiang Yuan with burning eyes.

Jiang Yuan pushed his plain mirror and continued.

Photoshop is a very interesting software.

The girls love it.

It has a wide range of applications, mainly because of its high degree of freedom, and in addition, it is 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 its entertainment side, such as retouching pictures, changing scenes and so on. If you spend an afternoon, you can post it on your Moments, and if you spend half an afternoon, you can send it to the leader's hot search.

Those who are willing to do it all 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, groom and friends feel at ease as if they were attending someone else's wedding.

But on the flipside of entertainment, Photoshop can also be brutal.

It can be used to dig official seals, and if it is used well, the prison sentence can be three years.

It can also synthesize photos for extortion, and Hunan Shuangfeng has developed it into an industry that specifically targets officials to commit crimes, with far-reaching consequences.

Of course, it can also be used to solve crimes and increase the difficulty of solving crimes infinitely.

In the provincial fingerprint battle, Jiang Yuan used LV4's Qingdao-style fingerprint analysis method, paired with LV3's Chongqing-style fingerprint analysis method, and image enhancement skills to kill all sides.

The continuous cracking of homicide cases actually meant that Jiang Yuan's fingerprint identification skills far exceeded the average level of provincial experts.

The fingerprints encountered now are beyond the difficulty of normal difficult fingerprints.

"Use Photoshop to deal with difficult fingerprints, and there are often surprises. Photoshop is PS. The focus of its use in our criminal investigation is to ensure the correctness 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 operations.

Practical explanations, actual combat in the front, and explanations in the back.

Chen Wenming straightened his back, watched Jiang Yuan's operation for a while, and then slowly imitated Cao Keyang next to him, and changed into a supine position.

Some things, if you look at them in a different way, your emotions will be different, and so will your sense of gain.

Just like Cao Keyang, at the beginning, he also straightened his back and looked at it, which made him feel very uncomfortable.

It will be much more comfortable when you lie down.

Cao Keyang's suppressed emotions were released, and at some point, he even smiled slightly.

"A group of people are still watching it with gusto." Chen Wenming looked around and saw all the students lying flat, and couldn't help but sigh: too high-level technology has greatly reduced everyone's enthusiasm for learning.

A trace inspector from the District Bureau heard Chen Wenming's words at this time, and he didn't agree with it. He looked at the screen and said, "Captain Chen, you have to look at it from a different angle, it's interesting."

"What angle."

"For example, I never knew that fingerprint identification can be done to this extent. It's like a magic skill." The trace inspection from the district bureau was only a little younger than Chen Wenming, and he spoke in a calm voice.

Chen Wenming still shook his head and said, "Dragon Slaying Technique."

Henjian next to him didn't care, and said: "It's over for being handsome. In the future, my nephew will ask me what I do all day long, and I will always have something to brag about. I can't just be awesome on TV every day, and the reality is nothing. .”

Cao Keyang nodded. In his heart, he naturally expected to become such an appraisal expert, but such words were not appropriate to say in front of colleagues in the unit, especially junior superiors.

I can't do it myself, but it is also a kind of joy to brag about it with my colleagues.

Jiang Yuan can be regarded as their colleague.

Chen Wenming knew better how difficult Jiang Yuan's fingerprint identification skills were to learn. PS skills were also boring, and mathematics and other related knowledge were needed later.

Therefore, Chen Wenming sighed even more: "It's hard to get together half a day of training, I hope he's handsome."

"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 much attention to the specific technical details.

If you don't understand some things in the first class, don't think that you can make up for them in the second class.

However, everyone is still interested in the extent to which high-level fingerprint identification methods can be achieved.

So, at this moment, there were more whispers and whispers in the auditorium, but everyone's smiles also increased.

Chen Wenming saw that the tracers next to him were against him, so he had nothing to say.

In fact, talking about the cutting-edge capabilities of a technology and discussing its boundaries is originally a training model.

For example, fingerprint technology, now has the ability to extract from clothes, bed sheets and other places, so we have to tell the front-line police through various means, otherwise, without the operation of the front-line police, only the research done in the laboratory , what's the use.

Similarly, the training of fingerprint collection is done every year by units at all levels in order to strengthen the training and raise awareness at the grassroots level so that they can do better and more.

The frontier extension of the DNA is more pronounced.In the early years, DNA testing could only be done on blood, saliva, human tissue, and **. Many places did not start to promote sweat until around 08. After another 10 years, grassroots policemen will update their understanding that everything the suspect has come into contact with You can try it everywhere.

Today's training, everyone originally participated in the study of fingerprint identification, so the first class was disappointing.

However, when it came to 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 come to give cutting-edge lectures are often not cutting-edge.

And what Jiang Yuan showed today, in the eyes of a group of trace policemen, can be called beautiful.

"Well, it's processed like this, let's run again." What Jiang Yuan was talking about was the processed fingerprint image.

The mark inspector in the front row couldn't help laughing: "It doesn't look like it at all."

"It's actually the same picture. This can be directly proved. If the suspect's lawyer raises this point, we can do a criminal investigation... Do you want to do it? It may take about 10 minutes..." Jiang Yuanke said politely Yes, if anyone has an opinion, they will pay attention to answer it.

The trace inspector in the front row waved his hand: "Don't worry about me, just follow your own syllabus."

In fact, Jiang Yuan didn't have any teaching syllabus, but he wasn't particularly interested in seeing the trace inspection, so he said, "Then let me continue, um, now it's time to mark the feature points again, this time, we still have to choose A smaller area..."

"Which area to choose specifically, my suggestion is to judge according to the finger shape."

"We have dug up two cases, and there are two sets of fingerprints for reference. From here, we can actually see a little bit of his hand habits."

"Well, you can actually use a little footprint identification thinking here..."

Jiang Yuan mentioned a little bit, but didn't say much.After all, today is a lecture on fingerprint identification, so try not to go astray as much as possible.

Chen Wenming sat up involuntarily.

He usually does fingerprints, in fact, he uses the thinking of footprints.

This is a natural choice. Humans have 10 fingers—a normal person. In terms of use, there are always some habitual movements and different operating techniques, including whether you like to use the left hand or the right hand, and whether you like to use one finger or two fingers. , Like the index finger and middle finger, or the middle finger and ring finger and so on.

It's just that unlike the development of footprint identification, fingerprints have no norms and rules in terms of usage habits.

Everyone is thinking about it.

Chen Wenming is also thinking about it, but there are not many opportunities to use it.

At this moment, he wanted to hear what Jiang Yuan had to say.

Although Dragon Slaying Art is in a state where there are no dragons to kill, but absorbing the essence of Dragon Slaying Art, it must be very good to slaughter cattle and sheep.

However, Jiang Yuan did not continue to talk about the footprint thinking of fingerprints.

Because the feature points of the fingerprint have been marked, and then send it to the fingerprint library to run, and new results will come out soon.

"Everyone see, after processing like this, and then comparing it with the existing fingerprints, it will be easy to get the result, because it is an assignment system, after processing it with PS, its assignment can obviously be improved..."

Jiang Yuan began to tell the main points.

The trace inspectors below were already in a hurry, and some people shouted: "Call first, call first!"

"It's dialing." Jiang Yuan took out his mobile phone from under the table, and said again: "Don't worry about this, it's in prison."

When the phone was dialed, Jiang Yuan reported the situation again, and the captain of the criminal police team on the opposite side naturally thanked him happily.

Even if the person is in prison, the case is still solved.

Moreover, criminal suspects have to continue to be prosecuted and receive additional sentences, which saves the time and energy of arresting.

Jiang Yuan suggested to continue digging into the case, and then hung up the phone.

The inspectors in the audience listened fascinated.

Especially the last part is just like a dream.

When a normal criminal police captain encounters a suggestion, he always chews up the suggestion and the person who suggested it and spits it out.

Jiang Yuan was a little used to the politeness of the criminal police chiefs from other counties, but seeing everyone's expressions, he quickly changed to a more serious look, and said, "Let's continue the course..."

Uh...

The phone vibrated again.

Jiang Yuan glanced at it, and quickly explained: "It's a call from Miaohe County. I don't know if there is any accident. I will answer it."

After speaking, Jiang Yuan answered the phone.

In the earphones, the voice of the head of the Miaohe County Criminal Police Brigade was deafening: "Jiang Yuan, thank you, he has been caught."

"That's great, congratulations."

"Congratulations to us. This case is thanks to you, and you saved the death case."

"Has the suspect confessed?"

"Not yet, it should be soon. We found some evidence in his home. A zero confession is fine. Confession is a matter of time." The head of the Miaohe County Criminal Police Brigade exchanged greetings, and hung up the phone after a while.

Turning his head, the eyes of everyone in the room were shining.

The long-lost passion rose again, and everyone fantasized about being the one who made the call.
