Chapter 19
Jiang Yuan took out the first fingerprint, which was only the front half of the fingerprint, and the position was relatively vague.

Facing such a fingerprint, the first thing Jiang Yuan has to do is to determine which finger it is.

After that, the fingerprint image is processed.

Finally, the feature points are marked.

After Jiang Yuan acquired the fingerprint skill, he used it a few times, and it just felt a little familiar, and now it is very smooth to operate.

I saw the somewhat blurred fingerprint image after zooming in. Under Jiang Yuan's mouse, it was constantly zoomed in and out, and the color scale, brightness and light and dark were changed from time to time. At the same time, Jiang Yuan kept marking the feature points.

Wang Zhong just felt dazzled, and after watching for a while, he couldn't stand it anymore.

The PS software has powerful built-in functions and a large number of shortcut keys to facilitate users to improve efficiency.

But for bystanders, if the user does not explain it or explain it, and press the shortcut key, the bystanders will be dizzy.

Just like Wang Zhong's state at this time.

"Come on, I'll go back first." Yan Ge sat down even more boringly, said hello, and went back to his office to get busy.

Wu Jun naturally looked at Wang Zhong, smiled and said, "Xiao Wang won't go back to work?"

"Do it... I'll watch it for a while, study and study, and then go back to work." Wang Zhong didn't understand Jiang Yuan's operation very well, but he knew that Jiang Yuan was dealing with fingerprints now.

In fact, even if Jiang Yuan explained this kind of operation to him in detail, he wouldn't be able to remember it. If he remembered it, he wouldn't be able to use it for a while.

Anyway, Wang Zhong just watched in a daze, and counted as much as he learned.

At least, he can learn something now. In the past, Wang Zhong followed Yan Ge, and he had nothing to learn.

In the process of image processing, Jiang Yuan marked four feature points by the way.After completing this step, he chose a direction from another corner, marked 4 feature points, and said: "First of all, let's take a look."

Wang Zhong only felt dazzled, and before he got into the state, he saw that Jiang Yuan had already let the software run.

After a while, 20 fingerprints appeared on the candidate list.

Jiang Yuan ruled them out one by one, and marked them again.

Wang Zhong soon got tired of watching.

Doing trace inspection and comparing fingerprints is extremely boring.

This process is like a person trying to find a twin for a hedgehog.

He can pull out 8 thorns first and compare them all over the world. If he fails, he can pull out several thorns again, or mix them with some of the previous 8 thorns, or form a separate team and continue to compare them all over the world. Until the ratio is right, check that all thorns are the same.

There is an old saying: 8 roots and 8 roots, 8 roots and 8 roots, the roots are different, hard and slender.

Jiang Yuan tirelessly compared for half an afternoon, and when it was time to get off work, he finally announced that the comparison of the first fingerprint had failed.

"Let's go home." Jiang Yuan packed his bags and prepared to leave work on time.

Wang Zhong seemed to be a physics enthusiast. He was in a trance and sleepy as if he had listened to a lecture on theoretical physics for half an afternoon. Now I have doubts about my own existence.

Jiang Yuan didn't care about that much, went home to eat meat, and shared the reward he got with his father by the way.

"I won an award just after I went to work. It's not bad." Jiang Fuzhen was very happy. As he said, he took out his mobile phone and called Aunt Hua, saying, "Do you know how much young people earn now? More than 1 yuan not much?"

"It should be quite a lot. We rent a two-bedroom apartment in our community for only one or two thousand. It depends on the decoration." Aunt Hua replied naturally: "The house I bought in the provincial capital a while ago costs only one or two thousand a month. Renting for three or four thousand is actually not worth it..."

"I said, but when we were farmers, 1 yuan was too much. Now I don't know. I just watch the money enter the account all day, and I don't know how much it is."

"You are Fuzhen, there must be many."

"I heard from my son that he was awarded 1 yuan for breaking a case at his work unit two days ago. I thought, are there so many rewards in work units now? Hahaha, I guess it's quite a lot... "

Aunt Hua's tone changed: "Is there such a high reward for being a policeman?"

"I also said that I have never heard of it. However, he solved a case 20 years ago. It is called a cold case on TV."

"Hiss, that's amazing."

"Well, their leaders also praised it. I just wanted to ask, don't let it be that the money has depreciated in the past two years..." Jiang Fuzhen laughed a few times, and hung up the phone.

Jiang Yuan looked up at his father and said, "Don't you go to the vegetable market every day?"

"Just to make sure. You don't know how bad inflation is, by the way, I forgot to ask..." Jiang Fuzhen picked up the phone on the spot and redialed.

After a brief pause, I heard a machine tone from the mobile phone: The number you dialed is in the middle of a call...

Jiang Fuzhen showed a rich smile.

……

the next day.

When Jiang Yuan arrived at the unit, he attacked the second fingerprint.

No fruit.

Day three.

Continued yesterday, to no avail.

Fourth day.

Jiang Yuan gave up the second fingerprint and began to compare the third fingerprint.

Compared with the last two fingerprints, although this fingerprint is also incomplete, the details of the residual lines are relatively rich.It is equivalent to a hedgehog with healthy coat and plump prickles.

Jiang Yuan then compared the details more closely.

Starting point, divergence point, small eye, small hook, joint point...

Jiang Yuan made the fingerprint map very large, and only a part of it was displayed on one screen, and he moved the mouse lightly to outline it carefully.

After finishing his daily work, Wang Zhong ran over to take a look as usual.

He stared at Jiang Yuan's operation, and felt that he seemed to be able to do it, but he also seemed unable to do it.

It's like facing a physics problem, the formula is known, and I feel that it is reasonable for him to write it this way, but if he wants to say what he thinks, his head seems to be caught in the door.

Wang Zhong watched and fell asleep again.

Hearing Jiang Yuan say "I got it" all the time, Wang Zhongcai opened his eyes like a bewitched toad, and asked, "You got it?"

"It should be this." Jiang Yuanxu pointed to the screen.

Wang Zhong leaned over in surprise, taking advantage of the time when Jiang Yuan checked again, nervously comparing.

"How is it?" Jiang Yuan asked politely.

"It seems... you won the competition?" Wang Zhong didn't know how to answer.For him, the fingerprints of a new case are very common, but the fingerprints of an old case, even the fingerprints of the current case, are not common.

If Wang Zhong had won by himself, he would probably jump up and shout twice now.

But Jiang Yuan obviously didn't intend to celebrate.

For him, the fingerprints of this case cannot be said to be simple, but they are not difficult either.

This is actually normal.Don't look at what Wang Zhong said about the series of thefts, and then the series of thefts, it is still incomparable with the "Liu Yu Injury Case" which has a huge social impact on serious injuries.The fingerprints involved were at least carefully screened by experts from Qinghe City.

And this "serial oil theft case in the high-speed service area" is not high-level at first glance. Although it involves a wide range of areas, the trace inspections involved in the detection are mainly the trace inspections of the county bureau.Although a certain county bureau may also have experts, the case may not be assigned to the experts.

For example, in Ningtai County, it is Wang Zhong who is doing it. If it can't be done, it just can't be done.

"This person seems to be in prison." Jiang Yuan opened the information of the suspect in the comparison, and saw a traditional prison photo with small eyes, flat nose, thin, flat mouth and slanted eyebrows.

"I was imprisoned a month ago. The time does not conflict." Wang Zhong took a quick look, heaved a sigh of relief, and then looked at the case, and said, "Look, he fought with someone in a nightclub and caused minor injuries. He was in a nightclub The money spent was probably earned by stealing oil."

Jiang Yuan asked: "Then now?"

"You should call Team Huang. Bring the evidence for interrogation, and I think we can bring out a few gangsters." Wang Zhong said with a flat mouth: "If Team Huang hears that you have solved the case again, he will be very happy."

Jiang Yuan smiled: "I've been a little free recently, and I don't have any other cases..."

"You can't say this." Wu Jun, who was originally leisurely, changed his expression immediately when he heard Jiang Yuan's words.

Jiang Yuan froze for a moment, then smiled embarrassedly: "Forgot, you can't say it's too busy, right?"

"Don't say this word..." Wu Jun sighed, lowered his head and looked at the phone unconsciously, as if it would ring at any moment.
