When Jiang Fuzhen received Jiang Yuan’s message, he was drinking duck shit-scented Phoenix Dancong and scrolling through his cell phone.
Jiang Fuzhen replied lightly "Okay" 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.
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 mobile phone and started making tea, adding: "Xiaoyuan has to work overtime again."
"Working overtime again? Civil servants are so busy too." 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 who can give him second-class merit if not him."
Aunt Hua agreed: "Xiaoyuan is indeed 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 looking for something for you." The third uncle couldn't help but said, "You bought the safe to be closed, but if you leave it open every day, what's the use of it?"
Aunt Hua complained: "Opening the safe is very tiring. The door is very heavy. It's okay when I push it, but when I pull it, my legs have to rub against the ground. I have to enter the password, check the irises, and put my eyes on it."
, and often couldn’t recognize it, so I just bought a filing cabinet..."
"Ahua, do 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..."
"Bring me some, I'll simmer some abalone for Xiaoyuan to make up for it." Jiang Fuzhen stood up decisively.
Aunt Hua also stood up: "My friend, Xiaoyuan doesn't have a partner yet. It's been so hard, so you must make up for it. I still have Yao Zhu and Jinhua ham there. Wait a minute and I'll find someone to push them over."
"Send a number to my WeChat account." Jiang Fuzhen raised his phone.
"Okay." Aunt Hua was not polite and asked, "How much do you want to cook?"
"Cook a pot and make it weigh four to five kilograms." Jiang Fuzhen said, and began to send messages, ordering old hens, ordering keel ribs, ordering chicken feet and pig trotters.
Dried abalone is complicated to make. In addition to being careful when drying it, it also takes a lot of work, fire and materials when simmering. One pound of abalone requires almost 10 pounds of other ingredients to simmer. The whole process only takes a few days to complete.
.
However, Jiangfu Town estimates that it will take Jiang Yuan a few days to return home, just in time to eat cooked abalone.
…
Criminal Police Brigade.
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.
Fingerprints are very small, but there are actually a lot of points that need attention. Especially for fingerprints that are highly incomplete and a bit blurry, you must consider the flow direction of the lines, the width of the fingerprint lines, the occurrence area of the characteristic points, and the location of the characteristic points.
The number should be considered comprehensively.
It should be said that the emergence of the automatic fingerprint comparison system has greatly reduced the workload of fingerprint comparison.
However, talking to 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 can't get it right.
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 are impurities.
Therefore, the conversation with the program is 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 computer screen.
The bloody fingerprint on the screen was as calm as an elite at this time, saying 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. In film and television works, you are almost certain to die. Even if you don't die, you will be injured and comatose for a long time. If you are unlucky, you will have to die.
After being disabled, he showed a 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 him on the shoulder when they met, and said with a smile: "I prayed to you before going out, to 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 a lot of things that people who do fingerprints can't do for a long time. He doesn't want to increase the 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 win the fingerprint. This confidence was built up through many competitions in the province's fingerprint competition.
Of course, even if you are confident, it is better not to say it carelessly.
Jiang Yuan returned to his seat and silently adjusted his fingerprints.
The old high-performance console is roaring again.
This time, he treated the fingerprint with the same mentality as impurities.
After some operations, when Jiang Yuan sent the query again, the target data category of the fingerprint directly selected the flat stamp library, and clicked out the "Scroll and Flat", "Scroll and Flat and Palmprint" libraries.
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 doing the sealing, the person to be sealed 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 control the sealing with the other fingers and palm.
Hold the sealer's entire hand, and then roll it with the sealer as the center in the direction of the thumb box and the other fingers pointing outwards...
All in all, the people responsible for rolling seals are actually specialized sealers, usually the police.
The advantage of this is that it can reflect all the details of the finger, including the internal pattern of the fingerprint line, the peripheral line system, the root seal line system, 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 for the fingerprint database. Unless...
Unless the printer is unprofessional.
As we all know, people will do unprofessional things.
As for the matter of sealing on three sides, 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 is simple.
It is what normal people understand as fingerprinting.
With his finger dipped in ink, he pressed the front side 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.
Impurities versus impurities, nothing to be ashamed of.
Jiang Yuan re-adjusted the characteristic points of the fingerprint, single-selected the plane stamp database, and compared them.
After two rounds, at noon, when Jiang Yuan retrace the third round of feature points, 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.
Undoubtedly a winner!
Sure enough, when single-selecting the flat printing library, the fingerprint comparison suddenly became easier.
Jiang Yuan breathed a sigh of relief.
Generally speaking, his fingerprints were more difficult to make than during the fingerprint battle.
Because of the fingerprint battle, it borrowed the skills 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 no easy way out.
Jiang Yuan chose to submit it in the fingerprint database, and soon the feedback was sent back.
Same recognition!
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 surprised.
Jiang Yuan nodded: "I'll call Team Huang."
"Old Huang must be very happy." Wu Jun said, then looked at his right hand, pondered it carefully, and thought to himself: Is this trick so easy to use?
