Chapter 267 Zhou Jian’s Worship (Please subscribe, please vote!)

"Wow, Captain Li, you came here so early today. I haven't seen you for a week. Tell me, where have you been this week?"

Ji Huanhuan just walked into the office in the morning and saw Li Xiang sitting there.

This is strange. I haven't seen Li Xiang this week. Why did he show up in the office early this morning?

"Huanhuan, this is your fault. Our captain's whereabouts have to be reported to you. Who are you to be the captain?"

"He Wenqiu, do you want to die that you dare to make my joke?"

During this period, the guidance team got along day and night and became very familiar with each other, so it was common for them to joke with each other.

Let the office be filled with firepower.

"Did you see Zhou Jian?"

"You should come right away. I saw you went to the cafeteria to eat."

Speaking of eating, Li Xiang's stomach suddenly growled. He hadn't eaten anything all night, and his stomach was already hungry.

Ji Huanhuan stood not far from Li Xiang, and happened to hear everything clearly, so she smiled and said, "You haven't had breakfast yet. Sister, go get you one. Do you want steamed buns or siomai?"

"Can I eat both?"

"No problem, just wait."

Ji Huanhuan left the office and was about to buy breakfast for Li Wanwan. As soon as he walked to the door, he saw Zhou Jian: "Zhou Jian, Captain Li just came to see you."

"Looking for me, where am I?"

Li Xiang was looking for him after disappearing for a week. Zhou Jian was a little surprised, thinking it was something important, and asked quickly.

"It's in the office, go and have a look."

"it is good."

Zhou Jian came to the office and saw Li Xiang sitting there: "Captain Li, are you looking for me?"

"Well, how's the recent progress of the uninhabited murder case?"

"Progress is slow. The facial recognition system of the police is too inefficient. We have to manually screen the results to compare them. Recently, everyone is almost face-blind in the photos they see."

During this time, everyone in the guidance team was comparing the photos of the victims digitally restored from the skulls. Using the old-fashioned portrait recognition system, the similarity was only [-] to [-]%, and the results included millions of people. , similar to the victim.

The difficulty for them to find the real victim among these people can be imagined.

Everyone’s face is pretty much the same, so it’s not an exaggeration to say you’re face-blind.

What's more, when the lesbians in the guidance group went back to look in the mirror at night, they all felt that they looked more like the victims.

"You told me last week that you wanted to optimize the portrait recognition system. I've built it. Do you want to take a look?"

"what?"

Li Xiangyu refused to stop until he was shocked, and he immediately put Zhou Jian to death with just one sentence.

It has only been a week, but Li Xiang has optimized the face recognition system?
How can this be?

As the era of feature phones transitions into smartphones, is it possible to simply change the appearance?

One week is only enough to change the software shell, modify the UI interface, and change the icons. How can it be possible to optimize the software?

Moreover, Zhou Jian understands that the gap between the old and new systems cannot be simply optimized. It is a version change and a complete rewriting of the underlying code. This workload, let alone one person in a week, is equivalent to a hundred people. Can't get it done in a week.

Now Li Xiang actually said that it only took him a week to get it done. Li Xiang did not see many people this week, but this... was a bit of a boast.

"Take it and try it."

Li Xiang threw a USB flash drive towards Zhou Jian and asked him to try it.

The others didn't know what was going on and came over curiously: "Captain Li, what is it?"

"What else can I do? I feel that it is hard for you to manually screen victim photos. I have optimized the portrait recognition system, and the recognition success rate has been greatly improved compared to before."

"Really?"

When everyone heard this, they were immediately overjoyed.

In the past week, they have been deeply poisoned by these photos. Now everyone looks like a victim and has long been overwhelmed.

At this time, I was naturally happy to hear that Li Xiang had actually optimized the portrait recognition system.

They didn't care whether Li Xiang could optimize the software in a week, they just needed to know that their beloved Captain Li was here to liberate them.

"Quick, Zhou Jian, install it on your computer and try it."

"Try it quickly, I can't wait."

Zhou Jian was helpless and wanted to explain that this was an impossible task, but seeing the ecstatic expressions of Li Xiang and other team members, he had no choice but to insert the USB disk into the computer and find the installation program.

Click Install.

installing……

The installation is complete.

Familiar software icons come into view.

It’s done, not even the icon has been changed.

Zhou Jian originally thought that Li Xiang would do something superficial for the sake of face, change the icon of the portrait recognition system, and then adjust the UI interface inside, make some small changes, and then say it is optimized, so that everyone can Rather convinced.

After all, it was only a week, so he could understand.

But now, you haven’t even changed the icon. Even if I want to help you tell this lie, I can’t.

Clicking on the icon made him even more desperate.

As long as the icons don’t change, don’t you even adjust the UI?

Even changing the color will be fine!

This way I can boast. I really don’t know what you have been optimizing this week.

Li Xiang suddenly saw the aggrieved expression on Zhou Jian's face and asked with some confusion: "Zhou Jian, what's wrong? Is it because the software can't be opened?"

"It can be opened."

It can be opened. What about optimization?

"Just open it and try it. I have already checked for bugs during the simulation. Can you try it again to see if there is any problem."

"it is good."

Since Li wants to speak, Zhou Jian will naturally execute it.

But nothing had changed by then, and he couldn't tell the lie.

One advantage of not changing the UI interface is that he does not have to familiarize himself with the software again and can start operating it according to his previous usage habits.

It doesn't matter if you don't try it. After trying it, Zhou Jian can clearly feel that the system runs smoother and the response speed is much faster than before.

Did Li Xiang really optimize the software?

try again.

Zhou Jian continued and uploaded the photos of the deceased recovered using skull digital restoration technology to the portrait recognition system to start comparison.

Select age range, gender and other parameters to start comparison.

I saw countless photos flashing on the left side of the screen. Every time a photo is successfully matched, it will be placed in the selection box on the right.

The screening processing speed is obviously much faster than the previous system, and the quality of the comparison is also relatively high, at least they look somewhat similar.

"Captain Li, you're back with breakfast." At this time, Ji Huanhuan came over with breakfast and handed it to Li Xiang.

"Thank you, Miss Huanhuan."

"Captain Li's mouth is so sweet, take it and eat it."

After taking the breakfast, Li Xiang solved the battle in three strokes, five divisions and two divisions. He was really hungry.

After eating, Li Xiang felt sleepy.

Seeing that Zhou Jian had already started trying, he felt that staying here was meaningless and he might as well sleep in the dormitory.

"You guys are busy first. Go back and catch up on your sleep. I haven't slept well these past few days. I'm really sleepy."

"it is good."

No one even raised their heads to look at Li Xiang. They stared at the computer screen with several pairs of eyes and said perfunctorily.

"It does seem to be much faster than before, and the quality of screening is also higher."

"Indeed, the software is indeed much better after optimization than before."

Everyone has used the previous portrait recognition system, and the tractor-like response speed was really frustrating sometimes.

But they have no ability to change this situation.

It's different now. Their captain Li Xiang is not only accomplished in criminal investigation, but is also a leading figure in software engineering development.

The chemical reaction produced by the combination of the two is really amazing.

Criminal investigation software doesn’t work?
No problem, optimize it yourself.

Just so capricious.

"Quick, quick, the results are out."

This time the speed is actually ten times faster than the old version. Regardless of the quality, at this speed, the optimization is very successful.

How did he do that?
Zhou Jian was puzzled. It was unheard of that the software could be optimized to this extent in just one week.

He himself is engaged in computers and knows that software development is not that simple. It requires programmers to type out the code line by line.

There are hundreds of millions of lines of code, and you can't complete it even if your keyboard smokes while typing on it.

"Awesome, it only matched more than 300 similar photos."

While Zhou Jian was stunned, others had already looked at the final result and were suddenly in disbelief.

In a population of hundreds of millions, it is very difficult to find similar people. The previous portrait recognition system had a low recognition rate because of its old version. In the end, more than 100 million similar people were identified, and they had to manually Verify these more than 100 million people.

The work efficiency is simply devastating.

But it is different now.

After Li Xiang optimized the software, only more than 300 people were screened out during this screening, and they were sorted from high to low based on similarity.

This greatly saves their manual screening time. Even if the last person found is the person they are looking for, there will only be more than 300 people.

This is completely different from the previous workload of 100 million people.

At this time, Zhou Jian was also awakened by the crowd's cries. He also saw the result, which once again shattered his outlook.

"I was superficial. I thought Captain Li only spent a week optimizing the portrait recognition system and just optimizing some art interfaces. The core things have not changed. I was wrong. Except for the icons and interface, he has not changed. Everything else has changed, and the core code here should have been completely changed."

"How did he do it? It's incredible."

Zhou Jian had an expression of disbelief on his face and murmured to himself.

Those outsiders were shocked when they saw this scene, but in his eyes, as an insider, this was simply a miracle.

Mission impossible.

Li wanted to finish.

"Is this difficult?" Ji Huanhuan asked curiously when he saw everyone's surprised expressions.

She studied law and was not very computer literate.

Especially when I saw Zhou Jian's surprised mouth that he could fit an egg in, I felt it was outrageous.

"It's not only difficult, it's simply god-level, you know? In my mind, Team Li is a god-like person."

For a person who majored in computer science, he knew deeply what this software meant. It took Li Xiang only one week to complete this work. In his opinion, it was incredible.

This cannot be accomplished by man. All he can think of is God.

"Personality worship is not popular nowadays, but we, Team Li, cannot be deified."

"Oh, I can't explain it to you. I won't talk about this anymore. Now that the results are out, we should all hurry up and investigate. There are only a few hundred people, so it will be quick."

"it is good."

This topic has been put aside for the time being. Everyone in the guidance team is busy again today, but fortunately, hope is right in front of us. There are only a few hundred photos to compare. Compared with the millions of photos before, this is nothing.

For a while, the office became quiet and everyone became busy again.

Everyone is comparing it carefully, and if they see someone who is undecided, two or three people will discuss it again.

Time passed by unknowingly. Everyone had a meal at noon and did not take a break, so they came back directly to continue the screening and comparison.

They were busy until 02:30 in the afternoon. Lai Jiyun's team found some clues: "Everyone come and take a look. I think this person looks like him. You should also take a look."

Her voice attracted the attention of others in the guidance group. They put down the photos in their hands and walked over.

"Let me take a look." Qi Liyan came over, leaned in front of the computer and looked at it carefully.

"Not to mention, the eyebrows are the most similar."

"Don't say it yet, really, take a look at her situation."

"Okay, I'll check." Zhou Jian quickly launched an investigation into this person.

"Tian Lifen, I haven't had any Internet data for ten years."

As soon as Zhou Jian saw this situation, he knew that this woman might be the person they were looking for.

"Great, keep digging."

Everyone saw hope, this person was highly suspicious.

"This person is from Yungui. Inform the police over there to investigate this person."

"Okay, I'll contact you right away."

The distance is relatively far, so there is no need for their guidance team to go there to verify. The verification work can be left to the Yunnan-Guizhou police.

The verification work took some time, and the next day, Tian Lifen's situation was notified over there.

"Tian Lifen is a child from the Yunnan-Guizhou Mountains. Her father died young and her mother remarried. She lived with her grandparents since she was a child. Ten years ago, Tian Lifen was admitted to college and left the mountains. After graduating from college, she said she found a job. Since then, she has been separated from her family. Tian Lifen’s grandfather also passed away five years ago, and he was still asking where Tian Lifen went before he died.”

"Why didn't they call the police?"

"The road in the mountains is not easy to walk, and because the old man was old, he didn't know that he would call the police if his granddaughter didn't come back. It wasn't until the Yungui police came to the door that they knew that his granddaughter was dead and they had to call the police."

"Has her mother been found? Let's collect a tube of blood."

"It should be soon. Let's buy the tickets. He Wenqiu and Zouping will work harder and go to Yunnan and Guizhou to have a look and bring back the DNA biological testing materials."

"Okay, I'll check the ticket and take the nearest train there."
