Chapter 582： Less is not enough (on)

"Fat, what is the difference between those substitutes, and myself?" Zhao Wei interjected and asked, if it can be distinguished, it is the best.

"For the time being, there is no difference in appearance." Guo Tailai smiled bitterly: "Unless the DNA is tested, the premise is that the original DNA sample can be compared."

"On the site of others, make a substitute that can be seen at a glance, can the fat man come back?" Or Zhao’s father can see that the fat man’s cost of care can’t be easily won: “The confidant bodyguards around Uday’s are recognized. Not coming out is a substitute, we want to recognize it in TV news, it is difficult!"

"However, the appearance is exactly the same for the time being, but the difference between them and the life of the substitute, there are some differences in temperament. If the depth of the research is deep, there should still be subtle differences." Guo Tailai pointed out: "After a period of time Time, maybe fat and thin will change slightly, which requires normal and regular records, careful screening. They are not twins after all, the difference in natural growth is still there."

"Well, it's also a way." Master Zhao nodded. After all, there are still two people, not twins, even if they are exactly the same now, but after a while, there will be differences, unless Saddam and his son can be self-disciplined to the point where they are always in sync with those. But obviously, is that possible? After all, the substitute is a substitute, how can it compare with myself?

This method can distinguish the differences between groups of people, but still can't find the right person from it. It is only by the frequency of occurrence on certain major occasions to determine which group of people is Saddam himself. If Saddam is smart enough, change the composition of the bodyguards around him from time to time. Several different avatars take turns, and the difficulty to be resolved will multiply.

"Right, fat man, if you are yourself, can you recognize it?" Master Zhao was old and refined, and finally asked.

"If you see it with your own eyes within half a year, you can." Guo Tailai said with great certainty: "But this clarity on TV is not good unless there is a special high-definition photo."

"You made a mark?" Grandpa Zhao is overjoyed.

"Just for my distinguishing mark." Guo Tailai did not conceal: "The length of the fine lines on the face and my face is 0.1 mm. My eyesight can be distinguished. Ordinary people can't. But after half a year, it's hard to say, grow. In different situations, the fine lines on the face will always change."

"That's the same as not. Even if you take a high-definition photo, the time to get it back is over, and the people who appear again don't know which one." Master Zhao nodded and sank for a while and said: "Then I will And above, you can't recognize it."

Guo Tailai's eyes can directly measure the difference of 0.1 micron. This was measured by the laser range finder in the State Key Laboratory of Shuimu University. Therefore, Guo Tai can distinguish the size difference of 0.1 mm, but others will definitely not. At least Saddam Hussein can't tell them, otherwise they won't find this problem face to face.

"In fact, I can't recognize it." Zhao is old and has experienced so many things. It is longer than Zhao Wei can see. He laughed and said: "When we look at the fun, we are always looking for it. Going to the door allows you to distinguish between strong people. Some things are still not to be mixed up, no good. Now it is very good, you should contribute when you contribute, you should withdraw when you withdraw, you are not a person on the officialdom, you should not worry about things. Fees that brain."

"Thank you grandfather for pointing." Guo Tailai smiled and thanked.

Father Zhao’s face was a smile, and he accepted the gratitude of Guo Tailai unceremoniously. Of course, he also understands the meaning of Guo Tailai looking for him. This is the granddaughter he has already identified. He is sure that he will not marry. This kind of busyness must help.

"Fat, is it possible to distinguish this difference in technology?" Zhao Wei is a engineering student. Since he can talk about this topic, he can't help but want to continue to go deeper. It is best to solve it technically. Don't worry about it.

"Yes!" Asked about the technical problems, Guo Tailai never let the sister disappointed.

Just answered a word, Zhao Wei’s eyes lit up, and even Zhao’s father was surprised, technically achievable?

"But it's not working now." Guo Tailai organized a vocabulary and said: "The powerful computer system can make judgments in a targeted manner, but the current chip is good, the video recognition algorithm is good, and the technology is still not closed. There are still some difficulties in achieving it for the time being."

"What is the specific?" Zhao asked excitedly. This has nothing to do with the previous things, purely to satisfy a female doctor's curiosity about the solution to the technical problem.

"The security system that my company is currently developing has a branch called the gait recognition system." Guo Tailai did not hide the secrets of the sister, and quickly explained: "It is through the analysis of the normal shape of a person walking. Posture to determine my identity. Everyone's gait from different to different environments is different, and like the fingerprint iris, it is a unique feature for everyone."

This kind of gait recognition, as long as a concept is put forward, Zhao Wei can immediately understand the principle, and the words are immediately relieved.

"The current problem is the current computer performance bottleneck and the optimization of the video recognition algorithm." Guo Tailai went on to say: "The company may need to build a supercomputing center in the next step, and continue to improve the algorithm and realize the video with super-computing computing power. Gait recognition, this is also very important for the safety of the company. But..."

"But what?" Zhao Yufei quickly asked.

"Even if there is a gait recognition system, it can only distinguish four different groups of people." Guo Tailai smiled bitterly: "Which is the Lord, there is no way to confirm, because we do not have the most primitive gait data of the Lord, so no The method is matched. Unless you can determine which one is your own, and then store the correct gait data, the next time, you can recognize it from the walking posture. In addition, the restriction is relatively large, and the requirements for video shooting are also very strict. It is necessary to compare the data in several directions at the same time."

"This gait recognition system can be used in the military's secret department!" After Zhao Yi understood the principle, it is easy to understand Guo Tai's restrictions, but the concept of this security system is used in the secret department. Big killer!

“Of course!” Guo Tailai replied with a smile: “After our company’s trial, I will recommend it to the military.”
