I don't want to solve the case when I'm a little policeman.

Chapter 523 The joy of fish, the surprise of persistence

Researching a topic is a very boring thing, no, Xu Zheng and Qi Guangyuan had just returned to work for two hours of overtime when Qi Guangyuan fell asleep on the table.

Xu Zheng didn't care about him, originally he was called here to discuss with him how different factors would affect the child's acquired appearance. As a result, when the two discussed, Qi Guangyuan's shortcomings were exposed.

Not enough talent.

It is said that he has been working for more than ten years, but the current analog portrait technology should still belong to the level where the elementary level is full and the advanced level is not yet reached.

This cannot be blamed on him, after all, his main job is not to make simulation portraits, but to analyze computer 3D technology.

Xu Zheng insisted on studying these rows of materials by himself. With his continuous efforts, a vague idea slowly formed about the influence of different factors on a child's appearance, but it was not enough.

However, he still gained something in the end. The biggest factor affecting a child's appearance is the acquired living environment. If a pair of twins are placed in the three eastern provinces and the Nanhai province, then when they grow up, the difference in appearance will definitely be very large.

The subject of Zheng Heming's research is this kind of acquired factors that affect the appearance of children. He wanted to find a model or personal experience, based on the acquired factors such as the appearance of the abducted child at the time, the genes of the parents, and the growth environment across the country. Abduct the child's appearance when he grows up.

Although the various aging software on the market are very advanced, there are still many abducted children who cannot be found with this kind of face recognition software.

Based on the reason, this acquired factor was not taken into account.

He wanted to research a method all at once, or ask a software development company to develop a new algorithm. Now that Xu Zheng thought about Zheng Heming's subject, he still had a very long way to go.

Because the material he has collected so far is too little, and there are too many acquired factors, the sound is different in ten miles, and the food is different in hundreds of miles. The influence of diet on appearance is a big factor.

The flower-growing country has a vast territory, and the diet structure of each ethnic group is also different.

From this point, Xu Zheng was inspired, and he planned to classify the backstage appearance factors of these abducted children according to the traditional eight major cuisines, plus the northeast cuisine and the western province cuisine.

After a day's research, Xu Zheng realized that diet has a high probability of shaping children's appearance far more than acquired factors such as deciduous tooth decay. Therefore, he plans to draw the appearance of abducted children based on different diets in different regions .

For example, Xu Zheng didn't know which province or city Jiang Lanxin's daughter Yan Mo was abducted to, so he drew ten pictures of 12-year-old Yan Mo using the top ten cuisines as the region.

Then draw a few photos of Yan Mo at the age of 12 with the acquired factor of deciduous teeth caries.

By analogy, he plans to use these acquired factors to draw a few photos of Yan Mo at the age of 12.

This workload is very heavy. Xu Zheng currently does not have a comprehensive grasp of these acquired factors, so he cannot be confident. There will definitely be errors, but in a short period of time, this stupid method is indeed the most suitable method.

As soon as he thought of it, Xu Zheng spread out the drawing paper, took out the photos of Jiang Lanxin and her ex-husband, and the photo of Yan Mo synthesized by computer aging software, and began to draw Yan Mo's 12-year-old appearance according to his idea.

According to the ten major cuisines, ten photos of Yan Mo can be drawn.

According to the eight acquired factors collected by Zheng Heming that affect appearance, eight pictures of Yan Mo can be drawn.

It takes 10 minutes for a photo, plus the time of thinking before drawing, and these sketches were not drawn until around twelve o'clock in the morning.

Xu Zheng is holding these 18 sketches of different types, on which are 18 little girls with different looks. At this moment, he really hopes that Yan Mo is among them. Now that he has drawn them, he must hand over the work of comparing the portraits to Qi Guangyuan Come and do it.

Qi Guangyuan woke up with sleepy eyes, looked at the time in a daze, the guy was not yet one o'clock in the morning, he looked at Xu Zheng, and asked casually: "What's the matter, did you have a new idea?
Let me tell you first, I am not as talented as you, and you tell me, you are really playing the piano with a cow."

Xu Zheng was too lazy to talk nonsense with him, so he threw 18 sketches in front of him, "You can use the computer to modify and color the sketches I drew, and use a filter tone to dark yellow R:255.

Or see for yourself. "

In fact, according to different regions, the skin color of people's faces is also different, but most of the photos on the school records are dark yellow, so it is not a big problem to consider the skin color.

Looking at the 18 sketches of girls in front of him, Qi Guangyuan woke up instantly, and seeing the names of the various cuisines marked on them, as well as various acquired factors such as deciduous tooth decay, obesity, thinness, etc., he also reacted to Xu Zheng's approach.

This is to reduce his teacher's subject by more than half, but regardless of the more than half, he also drew the 18 sketches in front of him. It is estimated that his teacher, Zheng Heming, can't say that he can draw 100% correctly.

In fact, Xu Zheng didn't dare to say 100%, but he was still [-] to [-]% sure.

The two continued to divide the work. Xu Zheng took out photos of Zhou Youfang and his wife, as well as a photo of his son Zhou Chengcheng when he was three years old, and followed the method just now to draw Zhou Chengcheng's appearance when he was 13 years old.

This painting took another three hours, and when Xu Zheng stopped writing, he saw Qi Guangyuan fell asleep on the table again.

His heart sank suddenly, Qi Guangyuan was able to fall asleep, which meant that the photos of Yan Mo he drew just now could not be compared.

Xu Zheng didn't wake up Qi Guangyuan immediately, but went to the bathroom first. The office building in the early morning was very quiet, and the sound of walking could echo in the corridor. After washing his face, he looked at his appearance in the mirror, and unexpectedly It feels both familiar and strange.

In a daze, Xu Zheng felt that he in the mirror had suddenly changed into Zhou Chengcheng's appearance.

The thought of "Fuck" startled him, obviously he was a little crazy now.

"Wow." Xu Zheng picked up the tap water and sprinkled it on his face, fell his head, but didn't dare to look up at the mirror in front of him anymore.

Back in the studio, Qi Guangyuan did not know when he woke up, and was taking the 18 sketches of Zhou Chengcheng he had drawn just now to touch up with the computer, and then compared them.

Seeing Xu Zheng coming back, Qi Guangyuan pointed to the hot tea on the table, "I made you a cup of tea, drink a few sips to refresh yourself, or if you choose not to drink it, maybe you can sleep for a while."

But when Xu Zheng picked up the teacup, he persuaded again: "Why are you so energetic, kid? It's common for parents to stay up late and play games in Internet cafes without sleeping, but you're doing mock portraits, and you don't think it's boring."

While sipping his tea, Xu Zheng smiled and said, "Zi Feiyu, how do you know Yu Zhile, you, it's time to compare the photos. Now I have finished drawing the simulated portraits of the two children, Yan Mo and Zhou Chengcheng.

For the time being, I can't grasp the other factors, so I can only achieve the present situation.

If they can't be compared, it can only be said that God's will has not arrived. "

Although Xu Zheng said dejected words, he did not choose to give up. Instead, he turned on the phone, found out the information that Bi Shangxue had passed on to him, randomly selected a child's information, and prepared to continue making simulated portraits according to the method he had just done.

After a while, just as Xu Zhenggang drew a sketch, Qi Guangyuan shouted, "Xiaozheng, come quickly, come quickly, my mother, how can this really compare?"

Xu Zheng turned his head to look, and saw Qi Guangyuan pinching his glasses with his right hand and pointing at the computer screen.
　I can’t write anymore, I took my eldest son to play in the ancient city today, it’s really more tiring than going to work.

　　Happy Friday everyone!
