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

Obviously, I can't use my dog nose, although there is still some smell left in the room from the case that happened the night before, but it is enough to choke outside, and there is no way to track it.

The only one that is used is the time rewind charm.

Fortunately, with the Grandmaster-level analog portrait technology, the purpose of the time regression charm is different, at least there is no need to keep tracking until you find a surveillance video that takes a positive photo of the suspect.

It's just that this case also has more troublesome places.

As he said to Feng Ju, even if he was blindfolded with stockings, he could draw people.

There's nothing wrong with that, it's really just "possible".

As for the white silk and black silk theory that Mu Yuan said before, it was pure nonsense, and he didn't put his hope on the point that the masked stockings were very transparent.

Rather than hope for that, expect these guys to rip it off halfway.

It is said that these guys stayed in this villa for an hour or two, and although they kept covering their faces in front of the victims, they put a fig leaf on the side...... Shame stockings ripped off?

Of course, even if he didn't tear it off, Mu Yuan still had a way.

These guys always show their faces before they enter the scene, after they leave the scene.

For this, Mu Yuan is full of confidence.

After going around in circles, the time regression charm was used again and again.

One picture after another kept reappearing in Mu Yuan's mind, although Mu Yuan's face did not change much, but his heart was full of anger.

At the same time, Mu Yuan was also very emotional, these guys can really hold back!

I covered my head the whole time......

This pair of stockings on his head not only makes others unrecognizable, but also prevents his colleagues from falling his hair on the ground, which is simply a blessing for hair loss suspects......

Fortunately, Mu Yuan had already prepared in his heart, since he couldn't see anything in the room, he would go outside to find it.

There is no need for Mu Yuan to go in person, Xiao Mao is still in the air at any time.

Mu Yuan had already learned before that these people were wearing masks into the community, but they were wearing stockings in the room, and they must have changed their clothes halfway, even if the time was short, it was enough for Mu Yuan to grasp their true colors.

After a few minutes, Mu Yuan breathed a sigh of relief and said, "Feng Ju, why don't you ...... Looking for a place to try?"

Feng Ju nodded and said, "Then let's go to the Jinchuan District Bureau." What do you need?"

"Colored pencils are fine. ”

The haggard middle-aged man was a little dazed, and said, "Feng Ju, you ...... What do you want to try?"

Feng Ju smiled very contagiously: "Analog portrait." It's the kind that is shown on TV, you describe the physical characteristics of the suspect, and we draw him. In this regard, Xiao Mu is an expert. ”

The haggard middle-aged man seemed to have been fed a mouthful of hot Xiang, his face was flushed, and he said, "Feng Ju, I haven't even seen what the suspect looks like, how do I know his physiognomy features?"

Feng Ju glanced at Mu Yuan helplessly, he couldn't explain it, and he couldn't explain it clearly.

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

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

The corners of Mu Yuan's mouth curled slightly, and he smiled: "Whether it is useful or not is a question that I need to consider, and you, you only need to think about how to recall the appearance of the suspect in stockings as much as possible." ”

The haggard middle-aged man was suddenly speechless.

At this moment, he was a little unhappy in his heart, but there was a sentence circling in his mind: capable people are quite proud, maybe this young man belongs to this kind of person!

As long as he can really solve the case, say this...... No problem at all.

"Since it's a portrait, it's good in our house. When my son used to be at home, he liked to draw, and there was no shortage of paper and pen. ”

Feng Ju looked at Mu Yuan and let him make up his own mind.

Mu Yuan was not picky about this, and smiled and said, "It's okay to save trouble." ”

......

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

Of course, that's all, Mu Yuan doesn't have the soul of gossip, and he doesn't have the habit of inquiring about other people's family affairs, not to mention that Wang Guobang said just now that he has a son in his family......

Naturally, Mu Yuan began the authentic Mu-style analog portrait questioning method.

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

It is obviously much easier to paint a person with stockings on his head than it is to paint a real portrait of a person, because many details are obscured.

Mu Yuan sketched one stroke at a time, crumpled the paper into a ball and threw it away......

Feng Ju and the others looked like people eating melons and watched from the side, full of confusion......

More than twenty minutes later, the eyes of Feng Ju and the others gradually showed a look of surprise, even Director Li had never seen Mu Yuan paint with his own eyes, and this was the first time.

As for the kingdom, it is full of admiration and incredible.

What Mu Yuan painted was a man with flesh-colored stockings on his head, although his facial features could be distinguished through the stockings, there was always a sense of seeing flowers in the fog.

What really shocked them was the realism of Mu Yuan's portraits.

In just 20 minutes, it is indeed not easy to draw such a realistic portrait.

Moreover, Wang Bangguo has also given an accurate answer, this portrait is exactly the same as one of the people who committed the robbery that night, and it is this person that he just described.

In Wang Bangguo's words, although he doesn't know the true face of this person, he can recognize the appearance of wearing stockings - well, this is an exaggeration, let alone turning into ashes, it is estimated that he may not know him when he takes off the stockings.

But now Wang Bangguo is at a loss, although he is not a policeman, he also knows that with this portrait alone, he does not want to find the suspect.

"What next?" asked Feng Ju at the right time.

Mu Yuan was extremely calm, and said with a smile: "Feng Ju also knows that some graphics processing technologies can process the blurry surveillance screen more clearly, and even many videos that do not have the possibility of recognition can see the content in the video more clearly after processing. ”

"I know that. Feng Ju said.

Mu Yuandao: "In fact, no matter how awesome the graphics processing technology is, it is also realized by algorithms written by people. Now this portrait with a covered face can be seen as a blurred picture, and all I have to do now is to remove this layer of occlusion from the outside and restore it. Of course, this restoration may not be completely accurate, but when used for face recognition, the problem should not be too big. ”

Feng Ju and the others looked at each other, and this explanation seemed to make some sense. But everyone is not stupid, and naturally knows that it is unimaginably difficult to do this.

However, Mu Yuan was not prepared to give them a chance to question at all, pretending to be a ghost...... Uh, pretended to compare and contrast on that portrait, looked and looked, and then began to sketch on a blank piece of paper......

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

He also gave an explanation: An important criterion for face recognition is the relative position of the facial features, because even if two people look similar, the distance between the facial features is actually slightly different.

The things involved in this are too professional, and Feng Ju and the others can only listen, and they are completely powerless to refute it.

As time passed, a new portrait was revealed.

His eyebrows, eyes, mouth and nose are very detailed, but some details on his face are not too meticulously processed.

But no matter how you look at it, this is a living person......

"Alright! The first suspect is done. Mu Yuan exhaled and said, "Next the second one!"

"Or ...... Let's see if we can identify this person?" Feng Ju said.

So far, he doesn't believe much in the portraits painted by Mu Yuan, which can perform face recognition.

It's just that it's really unthinkable, so Mu Yuan came over.

Of course, even if Mu Yuan is easy to brag about in the simulation portrait, his talent in surveillance video tracking is something Feng Ju has witnessed with his own eyes, so if this road doesn't work, he is ready to take Xiao Mu to Jinchuan District to watch the surveillance.

"It's okay to identify it first, you can do whatever you want, and I won't waste time. Mu Yuan said, "Mr. Wang, let's continue." ”

Wang Guobang's mood was very complicated, on the one hand, reason told him that the portrait should not be like this, but on the other hand, he desperately hoped that this was the real thing, and the person drawn by Mu Yuan was the suspect.

But no matter what he thought, he continued to be guided by Mu Yuan's words, and began to describe the characteristics of the remaining three suspects one by one.

I don't know if it's because of the experience of working together for the first time, which has become much easier later.

It took only half an hour to paint all the portraits of the three figures, but these people were still wearing stockings......

However, in the process of waiting, Director Luo asked people to take pictures of the portrait and send it back to the Criminal Investigation Brigade of the sub-bureau, and the results were fed back there.

There is indeed data feedback on face comparison, and more than a dozen people with a similarity of more than 90% are listed, even if those whose ages are seriously inconsistent are deducted, there are still eight.

It's a bit of a scratch.

Even if Mu Yuan is indeed painting the suspect himself, which of these people is the suspect who has been identified?

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

It was another hour of waiting, and the morning was quietly gone......

During this process, Director Luo continued to ask people to take pictures of the painted portraits and send them back to the police officers who stayed in the unit.

And every portrait can be compared to some people.

Just as the last portrait was finished and Director Luo was about to take a picture and send it back, a phone call came in.
