When the woman heard the news from Pengcheng, her whole person seemed to collapse, and she was left to sit in Gu Chen's seat and laugh dryly to hide the pain in her heart.

In other words, the woman knows that when she signs the judicial paternity certificate, it means that the daughter who has raised her for ten years may have to return to her biological parents.

Or if the woman knows that she is in a catastrophe, she takes the initiative to surrender to the public security organ before the paternity test results are out, which is a good option to reduce her criminal responsibility.

Obviously, if that's the case, then her purpose has been achieved.

Just before Gao Xu came with the appraisal results, she informed Gu Chen of the facts and took the last train to redeem herself for her guilt.

Gu Chen ignored the woman for the time being, and asked Gao Xu, "What did Pengcheng say over there?"

"Pengcheng has exploded, and everyone is shocked. Gao Xu said this, and it was difficult to hide the excitement in his heart.

"Gu Chen, do you know? We are the first of the seven working groups, and the only one that has completed the task, we have proved the new algorithm of face recognition technology, praised the feasibility of the age calculation method, and let us solve the case that has not been solved for more than ten years, which is a major victory. ”

Liao Kai saw Gao Xu gushing, and couldn't help but say: "The new face recognition algorithm, compared with the traditional needle in a haystack method of abducting and searching for people, can greatly reduce the scope of search, and if this technology can be successful, it will undoubtedly provide great help to the police handling the case." ”

However, through this search, the technical department also found many shortcomings. Gao Xu took out Gu Chen's sketch from the file bag, held it in his hand and said:

"Gu Chen, I have already sent this sketch of yours to Pengcheng, and they are using your sketch to compare and improve it with the model picture calculated by the machine before. ”

"The technology department and technology companies there are already working on re-orchestrating the calculation parameters, and they want to reverse the cross-age face recognition technology that the new algorithm loves based on the results obtained so far, and constantly improve more and more accurate calculation data. ”

"Senior Brother Gu is so powerful, he can actually outperform the calculations of high-tech machines over there with manual sketching?" Lu Weiwei was also quite surprised when she heard this.

Gao Xu and Liao Kai looked at each other, and the two were also quite embarrassed.

It stands to reason that machine calculations, whether in terms of accuracy or big data, should be better than human calculations.

But Gu Chen can use a photo of two or three years old to draw the person in the photo ten years later.

If it is a coincidence, Gao Xu thinks it is very weird.

Who could have coincidentally found that the data picture in their own database is exactly the same?

It can be said that if there was no picture of Gu Chen, maybe Gao Xu and Liao Kai would have to find the target person one by one among these hundreds of photos.

"Gu Chen, tell me honestly, how did you do it?" Gao Xu thought for a long time, but couldn't help but ask him.

"It's simple. Gu Chen casually thought of a reason, and prevaricated: "I drew a picture of Han Jingjing when she was two or three years old, and then drew a five-year-old according to his four-year-old appearance, and so on, and then came up with this picture." ”

"Is it really so amazing?" Gao Xu said shocked.

Over the years I have been in the police, I have seen a lot of soul painters in the police force, but there are almost none who can reach Gu Chen's level.

Lu Weiwei looked at Gu Chen with bright eyes: "My junior brother Gu is very good at painting, what he paints is like anything, his idol since he was a child is our famous painter A Guta in Jiangnan City, do you know Ah Guta?"

Lu Weiwei then looked at Gao Xu and Liao Kai.

The two looked at each other, shook their heads and said in unison, "No...... I don't know. ”

"Anyway, it's just a very good painter. Lu Weiwei didn't know how to explain it.

After all, Ah Gu is in the national calligraphy and painting circles, and he also enjoys a certain reputation, how could Gao Xu and Liao Kai, the two little policemen, know?

If it weren't for Gu Chen's reminder at the beginning, even Lu Weiwei wouldn't know that there was such a powerful wandering painter in Jiangnan City.

"Now that the DNA has been confirmed, what is the mood of Han Jingjing's parents over there in Pengcheng?" Seeing the sadness of Han Jingjing's adoptive mother in front of him, Gu Chen could basically guess the excitement of Han Jingjing's biological parents over there.

The two husbands and wives are overjoyed and are contacting relatives from all sides, and they may have a flight to Jiangnan City tonight. Gao Xu said.

"That is to say, tonight, Han Jingjing will be able to meet her biological parents who she hasn't seen for ten years?" Lu Weiwei suddenly longed: "Imagine such a picture, it seems that it only exists in TV dramas." ”

"Not only Han Jingjing's family and relatives, but also our leaders in Pengcheng will also make a special trip to accompany them. Liao Kai continued to add.

Lu Weiwei smiled: "Your leaders came over, probably to commend you two." ”

"This ...... I'm definitely not here to honor the two of us. Liao Kai directly denied it, then looked at Gu Chen in front of him, and said, "It is possible that he came to see Gu Chen." ”

"Look at me?" Gu Chen was a little inexplicably named, and he was also stunned: "See what I do?"

"Because of your sketch, it was a big blow to the engineers over there in Pengcheng, after all, you used the human brain to defeat the machine, and in terms of the accuracy of the cross-age calculation, it is obviously you Gu Chen who is better. ”

"So what?" asked Gu Chen.

"So?" Gao Xu continued: "So they came here this time, probably to visit you specifically and ask you for relevant details, and also for these engineers to better improve the cross-age calculation data of face recognition technology. ”

After thinking about it, Gao Xu suddenly smiled again: "Of course, it is also possible that he came to ask for help." ”

"Looking for Senior Brother Gu for help?" Lu Weiwei was also stunned for a moment, and hurriedly asked, "What are you looking for Senior Brother Gu for help?"

"That's it. Gao Xu couldn't speak, so he said shyly: "Didn't we exclude seven working groups, and we fought for nearly 50 days, but only our group took the lead in completing the goal." ”

"Even so, it also verifies the feasibility of the face recognition algorithm on the cross-age algorithm, but after all, the accuracy needs to be improved, we have completed the goal, but the other six teams are still looking for a needle in a haystack, so ......"

"Oh, I see, do you want me to help with the sketch?" Gu Chen also suddenly realized.

Liao Kai snapped his fingers: "Yes, yes, that's what it means, with your Gu Chen's help, the other six groups don't have to work so hard." ”

Gu Chen was a little embarrassed, and said, "I must help with this favor, if you need it, you can ask your colleagues over there to come to me, or send me the picture." ”

When Gao Xu and Liao Kai heard this, they saluted Gu Chen at that time.

"Gu Chen, this kindness of your Jiangnan City police, our Pengcheng police will not forget. ”

"In the future, if you Jiangnan City police have any needs, our Pengcheng police are duty-bound. ”

"You're welcome, it's all what should be done. Gu Chen didn't shirk this task, helping one is also helping, and two or three is also helping.

If you can use sketches and drawings to accurately identify abducted children, it may be of great help to tech companies to improve their calculations.

Once facial recognition technology is improved, it will bring good news to all disabled families who have been abducted and trafficked.

Such a good thing...... Gu Chen naturally wouldn't refuse.

After solving the problem here, Gu Chen returned to Han Jingjing's adoptive mother again and asked, "You also heard just now, Han Jingjing's biological parents and relatives are coming to Jiangnan City tonight, can you arrange it here?"

The woman raised her head, wiped her tears, and muttered, "Dang...... Absolutely. ”

"That's good. Gu Chen turned around and asked Gao Xu, "Do you want to book a hotel?"

"Of course. Gao Xu also walked over and said, "But the hotel has been booked, it's in the Jiangnan Hotel, you can contact the media reporters now, this is big news." ”

Lu Weiwei interjected: "Leave this to the superiors, Lao Wang will contact you." ”

"Good. Gao Xu nodded, and excitedly high-fived Liao Kai to celebrate, which was already a standard action for the two.

At this moment, Gu Chen brought a stool from the seat next to him, sat next to the woman, and asked, "Now you can explain, who did you buy Han Jingjing from back then?"

The woman was suddenly stunned, her face was a little heavy, and she didn't dare to look into Gu Chen's eyes.

"Look up and look at me. Gu Chen reminded on the side: "If you don't explain this, there will be more children from families, who will continue to be trafficked by these human traffickers who have been killed by God, can you bear it?"

"Big sister. Seeing that the woman was a little unmoved, Lu Weiwei also helped: "I don't think you look like a bad person, but buying abducted children from traffickers is a felony, there is no trafficking without trading, you can be regarded as an accomplice in this industrial chain, I hope you can understand this truth." ”

Seeing that the woman was a little shaken, Lu Weiwei turned on her mobile phone and showed the photos of the families of the abducted children, crying bitterly and even kowtowing.

"If you think a tragedy like this is supposed to happen, then you can shut up. ”

"I ...... I said, I said all. The woman looked at the photo in front of her, couldn't hold back the sadness in her heart anymore, and said, "However, I have a request, I hope you can agree." ”

"As long as it is reasonable and legal, we can consider it at our discretion. Gu Chen said.

"Thank you!" The woman calmed down, and said angrily: "Back then, my stomach was not angry, and after giving birth to two sons, my husband always wanted to have another daughter, but I couldn't help it." ”

"At this time, a friend who didn't know where my husband met said that there was a girl brought from out of town and asked my husband if he wanted to keep it as a daughter, as long as 20,000 yuan. ”

"My husband was also in love with his daughter at that time, and he agreed with a hot head, and it didn't take long for his friend to bring this three-year-old girl to my house. ”

"Crunch!" Gao Xu's fist was already creaking as he listened to the woman tell the story of the purchase.

Gu Chen also heard it obviously, but he just glanced sideways, turned his head and asked again: "Then the trafficker who sold Han Jingjing to your family as a daughter back then, can you find him now?"

The woman shook her head: "I can't find him, they are basically running around the country." ”

"Is there a photo of this trafficker?" Gu Chen asked again.

The woman fell silent again......

After more than ten seconds, the woman suddenly raised her head and said, "Okay...... It seems that there is one, let me think about it. ”

Gu Chen and Lu Weiwei didn't dare to make a sound, for fear of interrupting the woman's memory train.

"By the way, there's one in my space. The woman looked at Gu Chen with a melancholy look in her eyes and said, "It was my husband who bought Jing Jing from the trafficker at that time, and asked the trafficker's accomplice to help take the contract, and the trafficker was standing aside smoking at that time, but his accomplice accidentally photographed him in." ”

After getting this clue, Gu Chen didn't say a word, quickly clicked on his computer, handed the mouse to the woman, and said, "Open your space and find that photo." ”

"You wait. The woman took a deep breath and sat up straight.

She knew that confession and leniency were her only way out.

Since he took the initiative to come to the police station to surrender himself, he was ready to cooperate with the police in handling the case.

Although her husband was strongly opposed, the woman knew that this was the best way to protect her family.

"It's this one. The woman clicked on a photo album and found the photo of her husband holding a three-year-old quietly in her arms.

"This photo was taken on the day of the transaction, when the trafficker happened to be smoking a cigarette and talking on the phone, and his companion took a photo with Jingjing at the request of my husband, but it was this group photo that took the side face of the trafficker. ”

"Only a side face?" Gao Xu, who was gathered around the computer, couldn't help but cry out in disappointment.

"It's much better if it's a straight face, but it's hard to get a side face. Liao Kai also complained bitterly.

Gu Chen hesitated for a moment and asked the woman, "Are there any other photos of the face of a trafficker?"

The woman shook her head.

"Do you still have the contact information of the trafficker?" Gu Chen asked again.

The woman still shook her head.

"You don't know anything, so you dare to buy children from human traffickers?" Gao Xu is also very angry.

Since coming to the Furong Branch of Jiangnan City, Gao Xu has been controlling his emotions very well.

But only on the fact that he couldn't find human traffickers, Gao Xu couldn't help it.

The woman was aggrieved, lowered her head, and did not dare to look directly.

Gu Chen turned around and comforted: "Gao Xu, don't worry, maybe I can try." ”

"You...... Can you try it?" Gao Xu was stunned for a moment, but quickly reacted again: "Eh, yes, your Gu Chen's sketching skills are good, and you can draw the exact appearance of a three-year-old child when he is thirteen years old based on the photos of his three-year-old child, maybe you can try." ”

"Gu Chen, please. Liao Kai on the side also said anxiously.

Gu Chen took a deep breath, smiled at the two of them and said, "Don't worry, I just said to try, whether you can succeed or not depends on luck." ”

"Gu Chen, you can rest assured to paint, even if it doesn't work, we won't blame you. ”

"Yes, the most important thing is to find out this damn human trafficker, so that these people are separated, and if we don't catch this kind of person, we are policemen, do we still have the face to say that we are policemen?"

Compared with Gu Chen and Lu Weiwei's calmness, Gao Xu and Liao Kai have been checking for nearly 50 days in a row.

Therefore, the two can best understand how many ordinary families are suffering from human trafficking.

Therefore, emotionally, both of them are heavier.

They were eager and eager that Gu Chen could use his own technology to restore this side-faced trafficker.

I hope that through Gu Chen's sketch, this trafficker will be arrested.

"I'll try. Gu Chen moved his knuckles, and the woman stood up very interestingly and gave up her seat to Gu Chen.

Lu Weiwei was also very quick to ...... handed a large notebook into Gu Chen's hand.

Gu Chen didn't rush it, but turned on the face recognition skill and blinked twice quickly.

"Click!"

In my head, the voice of the camera sounded again.

In Gu Chen's visual interface, the option to scan and save appeared again.

Gu Chen chose to scan without hesitation......

Soon, the photograph, which was clipped out visually, was covered by a green net, and the lightning-like curves were constantly refreshed in the green grid.

"Ding!" As the scanned prompt sounded in my mind, the picture of the side face was three-dimensional, and suddenly became a three-dimensional image.

Gu Chen used his face recognition skills to complete the remaining half.

Subsequently, a three-dimensional picture of a humanoid appearance was intuitively displayed in front of Gu Chen.

Gu Chen used the three-dimensional picture to modulate the face picture into a positive face, and at this moment, the front face picture of the human trafficker had been completely exposed in front of Gu Chen.

At the same time, everyone saw that Gu Chen had been staring blankly at the computer, as if he was deserting, and they couldn't help whispering.

"Eh, I said Lu Weiwei, do you have to be in a daze when Gu Chen usually paints?" Gao Xu asked in a low voice.

Lu Weiwei shook her head: "This ...... I don't know very well, but every time Gu Chen wants to enlarge the move, he will be in a daze first......"

"I see. Before Lu Weiwei could finish speaking, Liao Kai answered: "Gu Chen must empty his head before he can concentrate." ”

"Yes...... Is that so?" Gao Xu said unconsciously.

Lu Weiwei nodded silently: "But ...... Maybe that's what he said?"

But what Gu Chen was doing, no one knew, let alone understood.

While everyone was whispering, Gu Chen had already picked up the 2B pencil and began to draw quickly in the notebook.

Lu Weiwei patted Gao Xu and Liao Kai on the shoulders: "Look, Senior Brother Gu has started." ”

Everyone's eyes kept switching between the computer and Gu Chen's notebook.

Gu Chen wrote quickly, although on the surface, his eyes were staring at the computer, but in fact, it was Gu Chen who used the three-dimensional image of face recognition as a reference in his own thinking space.

"This?" Gao Xu looked at the frame drawn by Gu Chen and couldn't help but be stunned for a moment.

"It's too fast, isn't it?" Liao Kai also had a numb scalp and a frozen gaze, feeling like he was admiring a master's painting.

And Lu Weiwei ...... looked at Gu Chen with bright eyes.

I was wondering in my heart, after Gu Chen finished solving this painting, should I ask him for a self-portrait?

......
