Meng Wentian said: "Of course, it is related, our computer image clarity software uses this principle to analyze. www.biquge.info If it is a painting or a photo, our software will always feel those pixels, and we don't know whether those pixels are the object itself or the external environment. ”

Speaking of this, Meng Wentian looked ahead, then pointed to a billboard on the side of the road in front and said: "To give you an example, do you see the small black shadow on the forehead of the beautiful woman on the right side of the billboard?

Huang Zibin glanced at the billboard and nodded, "Indeed." It's just that we think from common sense, this smudge is definitely not on her picture, it must be that the glass in front of the picture has been soiled. ”

Meng Wentian said with a smile: "So to restore the original appearance of this female star, we must first get rid of this stain." If we stand here and take a picture and send it to the computer, the computer software can't tell if the smudge should be taken out or not, because the computer doesn't know if there is a smudge on her forehead, unless the smudge is big enough to cover the area of the human face. But even if it knows that this smudge should be removed, it doesn't know how to fill the piece on its forehead that was dug up by it after this smudge, I don't know if the small area of the female star is convex or concave or flat, I don't know if it's fair or yellow wax or dark, at most it is filled with the surrounding skin color, it is estimated that she has no pockmarks, no pimples, no moles or something. ”

He paused and said, "So with just one picture, it is difficult for the computer to make the photos and images clear." Even if it is clearer, it is different from its original appearance, and there is a great subjective factor. ”

Huang Zibin smiled: "Don't tell me about these technical things, just talk about it." I should be able to understand. ”

Meng Wentian said embarrassedly: "Actually, I am also thinking and discussing the principle of this repair software when I say this now, I was in a hurry to read it last night, just rote memorization, and now chatting with you is equivalent to a good understanding process." ”

Huang Zibin asked in surprise: "Rote memorization?"

Meng Wentian didn't answer him, after all, it was a bit turbulent to recite a technical paper or something, and it was estimated that there were few people in this world who would do this, and few people could easily recite it.

He continued: "If we take two steps and send a photo to the computer, the computer immediately knows that the smudge is not the photo itself. Because as we walk, the angle of view of the photo changes, and the position of the smudge on the female celebrity's forehead in the photo also shifts. In this way, not only can the computer 'make up its mind' to get rid of this smudge to restore the beautiful and real appearance of the female star, but also know the original shape and color of some of the forehead that has been covered by the smudge. ”

Huang Zibin nodded and said, "I understand, the more pictures the computer gets, the more it can truly repair the object we are concerned about." ”

Meng Wentian said: "Yes. As long as you shoot a continuous video, even if the person you are concerned about is covered by smoke, after this software has been clearly processed many times, that person will gradually appear, and it will peel off the fog veil on that person layer by layer. Superimpose the graphics closest to his primary color and closest to his real shape in each frame of the picture, and restore it to an infinitely close to the real ......"

Seeing that the teahouse had arrived, Meng Wentian said simply: "In a word, the function of this 'clear software' is to extract useful elements from each frame of the picture and assemble them, so as to restore the real picture as much as possible." ”

Under the courtesy of the beautiful waitress, Meng Wentian and Huang Zibin sat in a small box and drank tea.

Waiting for the waiter to close the door, Meng Wentian asked, "Director Huang, what are you asking me to help you with?"

Although Huang Zibin said just now that he would ask him to clear the video, this was something that the two chatted about on the way to Nebula Technology, and Huang Zibin had no intention of asking him to help clear the video before. When he came to look for him, there must be something else, probably because he was bewitched by Huang Ziqi, and he had to think of a way for him to find clues about the murderer.

While waiting for Huang Zibin to speak, Meng Wentian said in his heart: "Huang Ziqi, Huang Ziqi, you are chasing ducks to the shelves, it is simply luck that I can help you catch the 'Golden Spider', and I have seen her, I know her somewhat, I know that that woman is bold and careful, has thinking that ordinary people do not have, and takes the road that others dare not take, otherwise she would have died a long time ago." With this understanding, I dared to think about the corresponding countermeasures at that time, and I dared to judge that she was drilling into the encirclement of Jiangde City. Now that I don't know anything about the murderer of the Shen family, what idea can I come up with?"

At this time, Huang Zibin held the teacup and said: "Originally, I came to you for only one thing, that is, we wanted to ask you to accompany him as Shen Hexuan's classmate, accompany him home, accompany him to play with him." Now there's one more thing, I want you to ask you to move your teacher to help us find the image of the murderer from a blurry video. ”

Meng Wentian didn't expect that the other party would arrange such an errand for him, and couldn't help asking: "Do you want to use Shen Hexuan as bait to lure those murderers to take the bait?" Now you don't even know what the murderer looks like, how many people don't know what they are in the dark, you are in the dark, you are in the dark, you are not afraid that they will kill him, you can't get anything?"

Huang Zibin didn't have any shame on his face, and said: "Now the top is pressing, requiring us to solve the case within ten days, we really have no choice, so we have to take this risky trick." If the murderer really came to destroy the door, they would definitely not let Shen Hexuan go, he is the only heir of the Shen family at present. ”

Speaking of this, Huang Zibin said: "Don't worry, we will loosen the outside and tighten the inside, and the two of you are surrounded by plainclothes protection 24 hours a day to ensure that you will not fall into a trap." And I know your ability, it may be difficult to deal with three or five murderers, but you definitely have the ability to delay for a few minutes. ”

Meng Wentian smiled bitterly: "You really believe in my ability. But what if the murderers have guns, what if they shoot them from a distance with a crossbow?"

Huang Zibin said: "We in Huaxia have very strict gun control, and they should not have guns. As for the bow and crossbow, the range is too close, and the first target they shoot is Shen Hexuan, it can't be you......"

Meng Wentian shook his head and said, "You guys are just guessing. Huaxia has a good control over guns, but there are still guns that are lost and smuggled in, and there are not no gun murders in recent years. …… , I'll be honest with you, I'm really a little scared, and my heart is very empty, mainly because I don't know anything about the murderer. Think about it, if I was playing a game with Shen Hexuan in an Internet café, and the murderer was sitting next to me, I knew it, and even chatted with him, how terrifying it would be. ”

Speaking of this, Meng Wentian said resolutely: "If you want me to cooperate with you, you can, but you must first let me see the photos of the murderer, so that I can have a little bottom in my heart, knowing whether they are men or women, old or young, I don't want to see a person with his hair standing up and preparing to flee, in that case I will go crazy." ”

Huang Ziqi shook his head and said helplessly: "We haven't seen what they look like ourselves. If we really know their appearance and other information, we won't do such a risky thing, just Buka just take the photo and search. …… We got a video from a store near Shen's house, but because it was night and the camera was an ordinary camera, the light was not clear. Now this tape has been sent to the Municipal Technical Investigation Department for clear processing, saying that it will take at least seven days to get the results out, the time is really too long, and the deadline given to us by the superior to solve the case is only ten days, we can't wait. ”

Meng Wentian said: "Your superiors are also fooling, can this case be solved in a few days?"

Huang Zibin asked, "If I ask your teacher to clear the video, how long will it take you?"

Meng Wentian shook his head and said, "I don't know." I just read a paper last night and knew there was such a thing. I don't know if she has mature software, so I'll have to ask her first. ”

Huang Zibin listened to his words, but he was not disappointed, because he had already prepared for this. In his mind, the Technical Investigation Department of the Municipal Police Department is not only in direct contact with the Huaxia Police Department, with the highest technical level in the field of technical investigation, but also has ties with various universities, what is the technology of clear video, they must be the first to know, since the Technical Investigation Department of the Municipal Police Department has said that it will take seven days, even if Meng Wentian's teacher is at a high level, it is impossible to spend less time than the Technical Investigation Department of the Municipal Police Department. Not to mention that he was still a high school student, and his teacher was only a high school teacher.

He admits that Teacher Meng Wentian's level is high, and she cannot be regarded as an ordinary high school teacher, otherwise she will not be able to win the first place in the competition in which many college students participate, but no matter how high a person's level is, can it be higher than a professional team? Moreover, there is more than one professional team.

Huang Zibin said: "Okay. If your teacher has this software, I can give you a copy of the video, as long as it doesn't leak before the case is solved. ”

Seeing that he said it lightly, Meng Wentian knew that Huang Zibin had no hope that his side would be able to make the video clear. Naturally, he wouldn't say anything, as long as it was a normal person, he would think so.

He changed the topic back to what he had just said, and asked, "By the way, how did you inform the murderer and tell them that Shen Hexuan was back?" If I guessed correctly, the murderer should be far away from the Shen family now, and it is impossible for him to stay near the Shen family and wait for you to arrest him." ”

Huang Zibin smiled bitterly: "There is no good way, just let Shen Hexuan and you show up with the Shen family and meet the neighbors of the Shen family or something." If the murderer really wants to kill the door, he should be noticed. ”
