At this point, Ding Mu grabbed the position of Ren Yunfei, who had prepared in advance, and the host had no choice. Pen Fun Pavilion www.biquge.info Even if humanity loses a lot, it should be advertised for Chihiro's robots, and customers should be satisfied.

Dong Chee-chang continued: "So what kind of problems are these two players facing today? Let's feel it together. First, let's look at an old photo. Everyone sees that an old photo is now a little mottled because of its age. Some important information points have become very vague. Probably only a little bit of the area remains today. Let's call this area the effective area. Now let's circle it out and zoom in later. ”

The scene was full of exclamations, including the guests who also showed surprised expressions.

"It's really hard. ”

"What's that? ”

There was a lot of discussion in the audience.

Then a new photo appeared on the stage, verifying that there were more than a dozen possible locations in this picture, and the checkmark was the correct answer. This location is the cornices of a building. There are a lot of similar ones. "According to what we just demonstrated, the contestants look at the old photos and then extract the similarities from the new ones. There are more than two or three similarities in the new photos. The active area of the old photo is only one in three thousand in the new photo. The host explained, and the audience exclaimed from time to time, "But we didn't show the contestants one." We're showing 30 new photos to the players, so if we add 30 new photos, it's only 1 in 90,000. ”

"I want to ask, this perverted project, I want to ask Na Na Wei, what do you think. The host said to the guests.

"Obviously, this challenge could be a little bit more challenging for the human players. Because our human brain has this property, that is, we remember things or perceive things, and we like to put them in a background to do it, for example, in this one, the background of this scenery, the trend of the mountain, you can see it in old photos. And the characteristic of the human brain is that it tries to think about these details as a whole. That's easy to be distracted by contextual information. Because background information becomes a distraction in this challenge. It is indeed a very big challenge for the human brain. Qianqian also faces a huge challenge because this small piece of information is very blurry, and in the new photo, it will also be blurred by the background information. In the end, whether the two contestants can find the right answer. It's just a question mark for me. ”

"Okay, next, will this task that Ding Mu and Qianqian have teamed up to complete meet the requirements of the old overseas Chinese in our scenario challenge to find their hometown? ”

"Love to lick soybean sauce, the strongest dipping sauce, two players, please go to the battle to challenge the position!"

Ding Mu and Chiqian stepped into the battle general challenge position and faced the computer screen. I can't see what's on stage anymore.

The host continued: "Behind the 30 photos of the new city location on the stage, there are photos of his old location. Let's take a look at what these 30 old photos look like. The big screen in the middle of the stage showed 30 old photos, which were almost completely different from the new ones. Take a screenshot of each old photo with a valid area. Particularly vague. They will be shown in the location photos of the new city. ”

The audience exclaimed again, this difficulty is really super high.

"Thirty old photos, small, and very blurry, sometimes you can see that they have similar parts. It's hard to find in old photos, let alone in a new city. Tung Chee-chang said: "Now we ask Professor Robert Li to choose an effective area. ”

The foreigner searched for a while, and chose an area that resembled tiles, which he thought was so vague that it was difficult to identify at all. And there are a lot of similarities in the new photos. There are a lot of similar areas in the new photos, so it's very difficult to identify.

Dong Jianchang said: "Qianqian, we will send you the photos selected by the guests and the pictures on the stage in a while." ”

Qianqian said: "I heard clearly." ”

The host continued, "Ding Mu, are you ready?"

Ding Mu said, "It's ready." ”

"Use your brain, drink eight more walnuts, and the challenge begins!"

Qianqian's cute eyes have changed from two vertical bars to a pointed shape, and they are swaying from side to side, and the monitor on the body shows that they are observing.

"I feel that the difficulty of this project is that we give too little information to the players, and it is a part, a vague part. There is too little information he can extract. I think for humans, the amount of information he wants to search for is very large, there are 30 paintings in the entire challenge completion area, and there are many areas that can be found in these 30 pictures, he needs to take this vague information, compare and check in many suspicious areas, for humans, it is too difficult. For the machine, the computing power is very strong, and it can be checked block by block step by step to find the most suitable one. ”

Liu Yuanqing explained: "For the machine, this technology is called image retrieval, but today we challenge this project, the difficulty has been greatly upgraded, the above pictures are blurry, basically can not meet the quality requirements of normal image retrieval, and another is that we only gave a very small piece this time, in fact, the amount of information is very small." ”

On the screen in front of Ding Mu, the picture selected by Robert Lee was displayed. Ding Mu just glanced at it, and Meimei prompted: "This should be a tile." Pay attention to the proportion and angle of the gaps between the tiles. I look for it by this. ”

Ding Mu immediately stepped down from the challenge position and went directly to the 30 pictures.

Now the audience began to exclaim! I wiped this too fast!

"He went looking for it, and he analyzed it. Micro expression expert Hua Longzhen explained.

Ding Mu is not looking for pictures like ordinary people, he is looking at them carefully at close range, his eyes are divine eyes, and looking at pictures from far and near has the same effect. Ding Mu stood directly in a position where he could look at the 30 pictures, and then glanced at it. After about five or six seconds, the image was already in his mind, and he closed his eyes.

Hua Longzhen immediately said: "He is not very sure. This was what he could see from Ding Mu's expression.

"No, I'm pretty sure. Ding Mu's divine ear heard Hua Longzhen's words, and he walked directly back to the battle general challenge position.

"Ah, is there an answer?" exclaimed in the guest seats. It's too fast.

Sure enough, Ding Mu directly wrote the number of the picture. Then he said, "Host, I've made my choice." ”
