Mu Yuan has already made a draft of the investigation of this case.

Obviously, my dog's nose is no longer useful. Although there were still some odor left in the room when the case happened the night before yesterday, it was very difficult to track it outside.

The only thing you use is the time traceback symbol.

Fortunately, with the master-level simulated portrait technology, the purpose of the time tracer is different. At least there is no need to keep track of it until a surveillance video is found to take the frontal photo of the suspect.

But this case also has some troublesome things.

As he said to Director Feng, even if he was covered with stockings, he might draw people.

This is nothing wrong, it is indeed just "possible".

As for the white and black stockings theory that Mu Yuan mentioned before, it was purely nonsense, and he did not put his hope on the point that masked stockings were very transparent.

Instead of relying on this, it is better to expect these guys to pull that thing off halfway.

It is said that these guys have been staying in this villa for an hour or two. Although they have been covering their faces in front of the victim, what if they have pulled off the fig leaf...the shame socks next to them?

Of course, even if it is not pulled down, Mu Yuan still has a way.

These guys always show their faces before entering the scene and after leaving the scene.

Mu Yuan is full of confidence in this.

After wandering around, the time tracer was used up again and again.

The scenes continued to reappear in Mu Yuan's mind. Although there was no change in Mu Yuan's face, there was a burst of anger in his heart.

While angry, Mu Yuan was also quite moved. These guys are so stubborn!

I covered my head all the way...

This silk stockings on the head can not only make others unable to recognize them, but also prevent their hair from falling to the ground. It is simply a blessing for suspects of hair loss...

Fortunately, Mu Yuan was already prepared. Since there was nothing in the room, he would go outside to find it.

Mu Yuan doesn't have to go there in person, Xiao Mao is still on standby in the air at any time.

Mu Yuan had already learned before that these people came into the community with masks, but they were wearing stockings in the room. They must have changed their clothes in the middle. Even if the time is short, it is enough for Mu Yuan to grasp their true faces.

A few minutes later, Mu Yuan breathed a sigh of relief and said, "Director Feng, why not... find a place to try?"

Director Feng nodded and said, "Then go to the Jinchuan District Branch. What do you need?"

“It’s good to have a colored pencil.”

The haggard middle-aged man was a little confused and said, "Director Feng, what do you... want to try?"

Director Feng smiled infectiously and said, "Simulation portraits are the kind played on TV. You can describe the suspect's appearance characteristics and we draw him. In this regard, Xiao Mu is an expert."

The haggard middle-aged man seemed to have been fed Rexiang, his face turned red, and said, "Director Feng, I didn't even see what the suspect looked like, how do you know his appearance?"

Director Feng looked at Mu Yuan helplessly. He could not explain it or explain it clearly.

Mu Yuan said: "You don't need to tell what the suspect looks like, you just need to remember what he looked like when he was wearing stockings. I think you should remember this, right?"

The haggard middle-aged man was stunned and said, "Of course I remember this, but... what's the use?"

Mu Yuan's mouth curled slightly and said with a smile: "Whether it is useful or not is something I need to consider, and you only need to consider how to recall the suspect's appearance in stockings as much as possible."

This haggard middle-aged man was speechless.

At this moment, he felt a little unhappy inside, but a sentence circling in his mind: All capable people are quite proud, maybe this young man belongs to this type of person!

As long as he can indeed solve the case, he will say this...it is absolutely fine.

"Since it's a portrait, it's better to be in our home. When my son was at home, he liked to draw, and he didn't lack paper or pen."

Director Feng looked at Mu Yuan and asked him to make his own decisions.

Mu Yuan was not picky about this and smiled and said, "It's good, it's easy to save trouble."

...

During the preparation process, Mu Yuan finally knew the name of this haggard middle-aged man: Wang Guobang.

Of course, that's all. Mu Yuan has no gossip and has no habit of inquiring about other people's family affairs. What's more, Wang Guobang just said that his family is a son...

Naturally getting to the point, Mu Yuan began the authentic Mu-style simulated portrait inquiry method.

There were four suspects at the scene, and of course Mu Yuan could only draw one by one.

Compared to the real portrait of a person, it is obviously much easier to draw a person with stockings on his head because many of the details are covered.

Mu Yuan outlined it with strokes and strokes, crumpled the paper into a ball, throwing it away...

Director Feng and others looked at each other like melon-eating crowds, feeling unconscious...

More than twenty minutes later, Director Feng and others gradually showed surprise in their eyes. Even Director Li had never seen Mu Yuan paint with his own eyes. This was the first time.

As for the Kingdom, there is a lot of appreciation and incredibility.

What Mu Yuan drew was a man with flesh-colored stockings on his head. Although he could tell his facial features through stockings, he always felt like he was watching flowers in the fog.

What really shocked them was the reality of the portraits painted by Mu Yuan.

It is really not easy to draw such a real portrait in just twenty minutes.

Moreover, Wang Bangguo has also given the exact answer. This portrait is exactly the same as one of the people who robbed that night, and what he just described is this person.

In Wang Bangguo's words, although he didn't know the true face of this person, he could recognize him even if he looked like a stocking in the stockings, right? This is an exaggeration. Not to mention it turned into ashes, he probably might not know him if he took off the stockings.

But now Wang Bangguo is confused. Although he is not a policeman, he also knows that he can't find the suspect with this portrait alone.

"What should I do next?" Director Feng asked in a timely manner.

Mu Yuan was extremely calm and said with a smile: "Director Feng thought he knew that some graphics processing techniques can process blurred surveillance images more clearly, and even many videos that do not have the possibility of recognition can clearly see the content in the video after processing."

"I know this." Director Feng said.

Mu Yuandao: "Actually, no matter how awesome the graphics processing technology is, it is also implemented using algorithms written by humans. Now this portrait with a masked face can be regarded as a blurred picture. What I want to do now is to remove the outer layer of occlusion and restore it. Of course, this kind of restoration is not necessarily completely accurate, but it should not be too big for face recognition."

Director Feng and others looked at each other. This explanation seemed to make some sense. But everyone is not a fool, so naturally they know that it is unimaginable to do this.

However, Mu Yuan was not ready to give them a chance to question, pretending to be a ghost... Uh, pretending to compete and compare, look and look, and then start outline on a piece of white paper...

Mu Yuan first set the position of his facial features, and the whole set of movements gave people a sense of skill, professionalism and meticulousness.

He also gave an explanation: an important criterion for facial recognition is the relative position of facial features, because even if two people who look very similar, there are actually slight differences in the distance between facial features.

The things involved here are too professional. Director Feng and others can only listen and are completely powerless to refute.

As time goes by, a brand new portrait gradually appears before everyone.

His eyebrows, eyes, mouth, nose and other paintings are very detailed, but some details on his face are not handled too carefully.

But no matter from which perspective, this is a vivid person...

"Okay! The first suspect is done." Mu Yuan breathed, and said, "Next second!"

"Or... let's see if we can identify this person's identity first?" Director Feng said.

So far, he has not believed in the portraits painted by Mu Yuan, which can perform facial recognition.

But it was really unimaginable that Mu Yuan came over.

Of course, even if Mu Yuan is making a simulator portrait, his talent in surveillance video tracking was witnessed by Director Feng himself. Therefore, if this road cannot be done, he will prepare to take Xiao Mu to Jinchuan District to watch surveillance.

"It's okay to use it for identification first. You can handle it as much as you want. I won't waste time." Mu Yuan said, "Mr. Wang, let's continue."

Wang Guobang was in a complicated mood. On the one hand, reason told him that the portrait should not be like this; but on the other hand, he urgently hoped that this was true, and the person Mu Yuan drew was the suspect.

But no matter what he thought, he continued to describe the characteristics of the remaining three suspects one by one under Mu Yuan's guidance.

I don’t know if it’s because of the first experience in cooperation, it’s much easier later.

The three portraits of the characters were all drawn in just half an hour, but these people were still wearing stockings...

However, while waiting, Director Luo asked someone to take a photo of the portrait and send it back to the Criminal Investigation Brigade of the Branch. The result was fed back.

There is indeed data feedback for face comparison, and more than a dozen people with similarity of more than 90% are listed. Even if those with serious age differences are deducted, there are still eight.

This makes people a little confused.

Even if Mu Yuan painted the suspect himself, which of these people identified was the suspect?

Director Feng looked up at Mu Yuan, who was busy erasing the stockings of the other three portraits, but he couldn't bear to disturb him.

This wait took another hour, and the morning was silently gone...

During this process, Director Luo continued to ask someone to take a picture of the drawn portrait and send it back to the police staying in the unit.

And every portrait can compare some people.
