Chapter 182 This Trick Works Well

x-on:x-on:江富城 was drinking duck shit-scented Phoenix Dancong and scrolling through her phone when she received Jiang Yuan’s message.

Jiang Fuzhen replied "Okay" lightly and fell into deep thought.

"What are you thinking about?" The third uncle sat across from him, taking a sip of tea, teasing the Butterfly Snow Dog at his feet, and keeping a little distance between the two dogs in Jiangfu Town.

The Doberman is only a few months old and has already surpassed his Siberian dog in size. Together, the two of them look like they dare to tease their uncle.

Jiang Fuzhen said "hum", put down his cell phone and started making tea, and said: "Xiaoyuan has to work overtime again." Even civil servants are so busy after working overtime again. "The third uncle took a sip of tea. He said there was a case," Jiang Fuzhen shook his head helplessly.

"It seems that second-class merit is not easy to obtain. Others work for 8 hours a day, and some go home after four or five hours. Jiang Yuan works for 10 hours, and second-class merit is not given to anyone else.

Aunt Hua agreed: "Xiaoyuan is really working too hard. In fact, it is better to let him come back and start a business. Just open a company to help everyone find things."

I'm helping you find something. "The third uncle couldn't help but said: "You bought the safe to be closed. If you leave it open every day, what's the use of it? "

Hua Bao said: "It's very tiring to open the safe. The door is so heavy. It's okay when I push it, but when I pull it, my legs have to rub against the ground.

I still have to enter the password, look at the irises, and place the eyes, but I often can’t recognize them, so I just treat them like buying a storage cabinet.” “Ahua, you have abalone there, I remember. "Jiang Fuzhen asked.

"Yes, I bought a lot of dried abalone back then. It was too troublesome to simmer it, and no one in my family would eat it."

Get me some, and I'll simmer some abalone for Xiaoyuan to make up for it. "Jiang Fuzhen stood up decisively.

Aunt Hua also stood up: "My dear, Xiaoyuan doesn't have a partner yet. It's such a hard work, so you must make up for it. I still have Yao Zhu and Jinhua ham waiting there. I'll find someone to push them over.

"Send a number to my WeChat account." Jiang Fuzhen raised his phone. "Okay." The flower god was not polite and asked, "How much do you want to cook?"

"If you want a pot, let's get it weighing four or five pounds." Jiang Fuzhen said, and started to send messages, ordering old hens, keel ribs, chicken feet and pig trotters. Dried abalone is complicated to make. In addition to being careful when cooking, it also takes a lot of work, fire and materials when simmering. One pound of abalone requires almost 1 pound of other ingredients to simmer. The whole process only takes a few days to complete. .

However, Jiang Fuzhen estimated that it would take Jiang Yuan a few days to return home, just in time to eat cooked abalone.

Punishment Team.

Jiang Yuan rubbed his waist and looked at the screen, waiting for something to come to mind before going up to mark and operate. Most of the time, Jiang Yuan looked at the image of fingerprints and thought about it.

The fingerprint is small, but there are actually many points that need attention. Especially for fingerprints that are highly incomplete and somewhat fuzzy, we must comprehensively consider them based on the flow direction of the lines, the width of the fingerprint mosquito lines, the appearance area of ​​the characteristic points, and the number of characteristic points. It should be said that the emergence of the automatic fingerprint comparison system has greatly reduced the workload of fingerprint comparison. However, the dialogue with the automatic fingerprint comparison system has become a complicated task.

Sometimes, even if you remove the essentials and extract the most essential and authentic fingerprints, you still cannot find the correct ones, because the fingerprints in the fingerprint database are not necessarily the most essential and authentic ones.

Sometimes, if you want to compare, what you need is impurities. Therefore, the conversation with the program is just like the conversation with the human being.

The initial exchanges and collisions all focused on the same question: Are you the best or the scum?

After identifying the other party's attributes, the correct way to communicate further or more deeply is to treat the essence like the essence and the dregs like dregs.

After trying for an afternoon and half a night, Jiang Yuan finally made a judgment:

You are scum.

He said it directly. Facing the bloody fingerprints on the computer screen, he was as calm as an elite and said nothing.

Let's talk about it tomorrow. "Jiang Yuan tapped the bloody fingerprint with his finger, then left the office and went directly to the dormitory to rest.

It was too late, and he was a little afraid to go home alone.

I have seen too many cases recently. Wouldn't it be terrible if I met a killer who had been released from prison, a retired killer, or a killer who killed people and silenced them?

Especially on the night before a murder case is about to be solved, you choose to walk alone at night. This kind of death is almost certain in film and television works. Even if you don't die, you will have to be injured and comatose for a long time. If you are unlucky, you will have to die. After being disabled, he showed the smile of a sunny life.

Jiang Yuan returned to the dormitory, locked the door, and slept peacefully.

the next day,

sunny

Jiang Yuan deliberately slept until everyone was at work, then got up to wash up, and then followed everyone back to the office.

Wu Jun followed him there, patted his shoulder when they met, and said with a smile, "I prayed to you before I went out. I wish you some good luck."

Thank you Master. "Jiang Yuan thanked him.

"How's it going? Is there any hope?" Wu Jun is also knowledgeable. He has seen many fingerprints done by people who have been unable to do it for a long time. He didn't want to put more pressure on Jiang Yuan.

Jiang Yuan nodded and said: "It went very smoothly.

He felt that if the rhythm was good today, he would be able to get the fingerprint. This kind of confidence was established through many successful competitions in fingerprint battles across the province.

Of course, even if you are confident, it's better not to say it carelessly. Jiang Yuan returned to his seat and silently adjusted his fingerprints.

There are libraries such as "Scrolling and Plane", "Scrolling and Plane and Palmprint".

The so-called rolling refers to rolling stamping, also called three-sided stamping.

To be honest, this is a more advanced way of stamping, and the operation is quite complicated.

When stamping, the person to be stamped needs to stand on the stamping table, and the stamper should stand on his left side, pinch the two sides of the second knuckle of the finger that lifts the stamp with his right thumb and index finger, and control the whole hand of the stamper with the remaining fingers and palm, and then roll with the stamper as the center in the direction of the thumb box and the remaining fingers outward.

In short, the rolling stamping is actually responsible for stamping by a special stamper, usually a policeman.

The advantage of doing this is that it can reflect all the details of the finger. Including the internal pattern of the fingerprint line, the outer line system, the root seal line system, the triangle, etc.

In theory, any part of the fingerprint left by this person in the future can be compared with the fingerprint of the three-sided stamping. Therefore, rolling stamping is a great enrichment of the fingerprint library. Unless... the stamper is not professional

As we all know, people will do unprofessional things.

And the three-sided stamping is still a bit difficult. Although serious training and doing dozens of finger tests can help you master the key points. However, as we all know, people are not serious. Jiang Yuan has faced too few fingerprints, and the error tolerance rate is very low. In comparison, plane printing is simple. It is what normal people understand as fingerprinting.

Cut the finger with ink evenly, press it vertically on the fingerprint card from the front. Although the recorded fingerprint is not complete, the fingerprints Jiang Yuan has now obtained are all within the range of plane printing. Impurities against impurities, there is nothing to be embarrassed about.

Jiang Yuan readjusted the feature points of the fingerprints, selected the plane printing library, and compared them.

After two rounds, at noon, when Jiang Yuan re-traced the third round of feature points, the fingerprint ranked 12th made Jiang Yuan stop. Jiang Yuan drank a sip of tea, then enlarged the two fingerprint images, and checked them one by one. There was no doubt that they were matched!

Sure enough, when the plane printing library was selected, the fingerprint comparison became easy all of a sudden. Jiang Yuan breathed a sigh of relief.

In fact, his fingerprint was more difficult than the one during the fingerprint battle.

Because in the fingerprint battle, he borrowed the skills of image enhancement, which was equivalent to a dimensionality reduction attack on the previous generation of trace inspectors.

This time, the fingerprint comparison was more or less hard-hitting, but there was no easy way to deal with the backlog of murder cases. Jiang Yuan chose to submit it in the fingerprint database, and soon, the feedback was sent back. The same identification

Jiang Yuan stood up and stretched, his bones snapped, he picked up the phone, and said to Wu Jun: "It's matched.

"Huh, really?" Wu Jun was stunned. Jiang Yuan nodded, "I'll call Captain Huang."

Old Huang must be very happy." Wu Jun said, and then looked at his right hand, concentrating on thinking, thinking: Is this trick so useful?
