Chapter 182 This trick is easy to use

@@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 opposite, took a sip of tea, teased the Butterfly Snow Dog at his feet, and kept the two dogs in Jiangfu Town a little further apart.

Doberman is only a few months old, and his size has already surpassed that of his Siberian dog. 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 get. 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, ordering keel ribs, ordering chicken feet and pig trotters and so on. 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, it must be comprehensively considered based on the flow direction of the lines, the width of the fingerprint mosquito lines, the occurrence 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 were all about 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 encountered 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 with my hand before going out, so I can bring 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 could hope to get the fingerprint. This kind of confidence was established through many 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 the rolling seal, also called the three-sided seal.

To put it bluntly, this is a relatively advanced sealing method, and the operation is quite complicated.

When making a seal, the person who is being made needs to stand facing the sealing table. The sealer should stand on his left side, use his right thumb and index finger to pinch both sides of the second knuckle of the sealing finger, and the other fingers and palms of the hand. Control the entire hand of the person who is making the seal, and then roll the hand in the direction of the thumb box and the other fingers outward, with the person who is making the seal as the center.

All in all, the person responsible for rolling seals is actually a dedicated sealer, usually the police.

The advantage of this is that all the details of the fingers can be reflected. Including the internal patterns of fingerprint lines, peripheral line systems, root seal line systems, triangles, etc.

Theoretically, any part of the fingerprint left by this person in the future can be compared with the fingerprint printed on three sides. Therefore, rolling stamps are a great enrichment of the fingerprint library. Unless... the person in Yinyin is unprofessional

As we all know, people do unprofessional things.

As for the three-sided seal, it is still a bit difficult. Even if you train carefully and do dozens of fingers, you can master the key points. But, as we all know, people just don’t take things seriously. Jiang Yuan faced too few fingerprints, and the error tolerance rate was very low. In comparison, flat printing was simple. It was what normal people understood as fingerprinting.

The fingers that smoothed the ink were pressed vertically onto the fingerprint card. Although the recorded fingerprints were not complete, the fingerprints Jiang Yuan now obtained were all within the range of flat printing. Impurity versus impurity, nothing to be ashamed of.

Jiang Yuan re-adjusted the characteristic points of the fingerprint, single-selected the plane stamp library, and compared it.

After two rounds of this, at noon, when Jiang Yuan retrace the feature points of the third round, the fingerprint ranked 12th made Jiang Yuan stop. Jiang Yuan took a sip of tea, then enlarged the two fingerprints and checked them one by one. There was no doubt that they were successful!

Sure enough, when single-selecting the flat printing library, the fingerprint comparison suddenly became easier. Jiang Yuan breathed a sigh of relief.

Speaking of which, his fingerprints were more difficult to make than during the fingerprint battle.

Because of the fingerprint battle, he borrowed the technology of image enhancement, which is equivalent to dimensionality reduction and defeated the previous generation of fingerprint inspection.

The fingerprint comparison this time was more or less head-on. However, with the backlog of murder cases, there is nothing easy about it. Jiang Yuan chose to submit it in the fingerprint database, and soon the feedback was sent back. Same identification

Jiang Yuan stood up and stretched, his bones crackling. He picked up his phone and said to Wu Jun, "I won the competition."

"Hey, is it true?" Wu Jun was stunned. Jiang Yuan nodded, "I'll call Team Huang."

Lao Huang must be extremely happy. "Wu Jun said this, then looked at his right hand, pondered it carefully, and thought to himself: Is this move so easy to use?
