Research topics are a very boring thing, no, Xu Zheng and Qi Guangyuan just worked overtime for two hours when they went back, and Qi Guangyuan fell asleep on the table.

Xu Zheng didn't care about him, he originally called him to discuss with him what different factors have on the child's acquired appearance, but as a result, when the two discussed, Qi Guangyuan's shortcomings were exposed.

Talent is not enough.

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

He can't be blamed for this, after all, his main job is not to make analog portraits, but computer 3D technical analysis.

Xu Zheng insisted on studying this row of materials alone, and the influence of different factors on the appearance of children was under his continuous efforts, and the idea of a model lake slowly formed, but it was not enough.

However, he still has some gains after all, the biggest factor affecting the appearance of the child is the acquired living environment, if a pair of twins are placed in the three eastern provinces and the South China Sea Province, then when they grow up, the difference in physiognomy will definitely be very large.

Zheng Heming's research topic is the change of this acquired factor on the child's appearance, and he wants to find a model or personal experience to directly draw the appearance of the abducted child when he grows up, based on the appearance of the abducted child at that time, the genes of the parents, the growth environment of various parts of the country, and other acquired factors.

Although all kinds of aging software on the market are very advanced, there are still many abducted children who cannot find this kind of face recognition software.

For the reason, this acquired factor is not taken into account.

He wants to develop a method at once, or let a software development company develop a new algorithm, and Xu Zheng still thinks about Zheng Heming's project has a very long way to go.

Because he has collected too few materials so far, and there are too many acquired factors, ten miles of different sounds, hundreds of miles of different food, the impact of diet on appearance is a big factor.

The country of growing flowers has a vast area, and the dietary structure of each ethnic group is also different.

From this point in mind, Xu Zheng was inspired to classify the backstage appearance factors of these abducted children according to the traditional eight cuisines, plus the cuisine of the Northeast and the Western Province.

After a day's research, Xu Zheng saw that the formation of diet for children's appearance is far more likely than acquired factors such as deciduous teeth and dental caries, so he plans to draw the appearance of abducted children based on the different diets of different regions.

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

Then use the acquired factor of baby teeth and tooth decay to draw a few more photos of Yan Mo at the age of twelve.

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

This workload is very large, Xu Zheng currently does not have a comprehensive grasp of these acquired factors, and he can't 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, as well as the photos of Yan Mo synthesized by the computer aging software, and began to draw Yan Mo's twelve-year-old appearance according to his ideas.

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

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

Ten minutes for a photograph, plus the time it took to think about it, it wasn't until about twelve o'clock in the morning that the sketches were drawn.

Xu Zheng was holding these 18 sketches of different types, on which were 18 little girls with different appearances, at this moment he really hoped that Yan Mo was among them, since it had been drawn, as for the portrait comparison, it would definitely be handed over to Qi Guangyuan to do.

Qi Guangyuan woke up with sleepy eyes, looked at the time with his eyes in a daze, the good guy was not yet one o'clock in the morning, he looked at Xu Zheng, and asked casually: "What's the matter, do you have a new idea again?"

I'll tell you first, I'm not as talented as you, and if you tell me, you're really playing the piano to a cow..."

Xu Zheng didn't bother to talk nonsense with him, and directly threw 18 sketches in front of him, "You can modify and color these sketches I drew with the computer, and use the dark yellow r:255 filter color uniformly."

Or see for yourself. ”

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

Looking at the 18 sketches of the girl in front of him, Qi Guangyuan instantly sobered up, and then saw the names of various cuisines marked on them, as well as various acquired factors such as baby teeth, caries, fat, thinness, etc., he also reacted to Xu Zheng's approach.

This is to reduce his teacher's subject by more than half, but don't look at this half, he also drew the 18 sketches in front of him, it is estimated that his teacher, Zheng Heming, does not dare to say that he can draw 100% correctly.

In fact, Xu Zheng didn't dare to say 100%, but he was still six or seven percent sure.

The two continued to divide labor, Xu Zheng took out the photos of Zhou Youfang and his wife, as well as the photos of his son Zhou Chengcheng when he was three years old, and drew Zhou Chengcheng's appearance when he was thirteen years old according to the method just now.

This painting lasted for more than three hours, and when Xu Zheng stopped writing, he saw Qi Guangyuan falling asleep on the table again.

His heart sank suddenly, Qi Guangyuan could fall asleep, which means that the photo of Yan Mo he just drew was not compared.

Xu Zheng didn't wake up Qi Guangyuan immediately, but went to the bathroom first, the office building in the early morning seemed very quiet, the sound of walking could echo in the corridor, wash his face, he looked at his appearance in the mirror, and felt familiar and unfamiliar.

Suddenly, Xu Zheng felt that he in the mirror had suddenly become Zhou Chengcheng's appearance.

"Damn—" the thought startled him, and it was clear that he was now a little mad.

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 didn't know when he woke up, and he was taking the 18 sketches of Zhou Chengcheng that he had just drawn to polish them with the computer, and then compare them.

Seeing Xu Zheng coming back, Qi Guangyuan pointed to the hot tea on the table, "I made you a cup of tea, drink two sips to wake up, or you choose not to drink it, maybe sleep for a while." ”

But seeing Xu Zheng holding up the teacup, he persuaded again: "Why are you so energetic, people stay up late in Internet cafes to play games and not sleep is a parent's convenience, but you are doing a simulated portrait, and you are not boring." ”

Xu Zheng snorted the tea and said with a smile: "Zi Fei fish, you know the joy of fish, you, hurry up and compare the photos is the right thing." Now I have finished painting the simulated portraits of Yan Mo and Zhou Chengcheng.

For the time being, I can't grasp other factors, so I can only get to the point where I am now.

If they can't be compared, it can only be said that the will of God has not arrived. ”

Although Xu Zheng said frustrating words, he did not choose to give up, but turned on his mobile phone, found out the information passed to him by Bi Shangxue, randomly selected a child's information, and prepared to continue to make a simulated portrait according to the method he had just made.

After a while, just as Xu Zheng had just drawn a sketch, Qi Guangyuan shouted over there, "Xiaozheng, come on, come on, my mother, this... How is this really compared? ”

Xu Zheng turned his head to look, only to see Qi Guangyuan pinching his glasses in his right hand and pointing at the computer screen, standing in place and stomping his feet, shouting "My mother" in his mouth!
