Chapter 50: Impact from technology

"Hello everyone, let me introduce myself. My name is Zhao Jianguo. I am from ..." The head of the Public Security Department sitting on the stage began to speak. This is a middle-aged man who looks like he has a sense of dignity on both sides of him. There are five other men and two women, and a total of eight people came from the Public Security Department this time. "First of all, thank you for taking the time to participate in the project proposal in your busy schedule ..."
凡 Liu Fan listened carefully to every word that Zhao Jianguo said. According to Zhao Jianguo, this bidding project was in a sense a need to update the police's existing face recognition technology. He first affirmed the contribution that face recognition has made to public security and the fight against crime over the years, and also provided data to support his claims.
同时 But at the same time, Zhao Jianguo said that the existing face recognition technology still has many shortcomings, so this time there was a tender, hoping that some companies can bring a relatively large technological leap. Further assist the police in cracking down on criminals.
Face recognition has always been a difficult subject because it has too many influencing factors. In fact, the principle basis of face recognition can be simply understood as feature extraction and comparison and construction of features.
But when the environment, light, or even the appearance of the character itself changes, the extraction and processing of features will become extremely difficult. For example, in a haze night environment with very low visibility, wearing a hat and a mask will basically make face recognition useless.
Not to mention that there are many problems such as visual illusion and incomplete face shooting caused by angles.
Many artificial intelligence companies now claim 99.9% accuracy, but this is under the premise of clear resolution, normal light, and complete face.
And these main problems that artificial intelligence now faces are exactly what criminals often do. Traveling at night, face occlusion, cosmetic makeup, avoiding the camera ...
Therefore, the further technological revolution of face recognition has always been anxiously anticipated by the police.
Zhao Jianguo clearly described the past achievements, current needs, positioning, and future planning issues. Next, various companies began to propose.
The order of proposals has been determined before. A total of fifteen companies, Huawei is ranked tenth. Everyone will go up one by one in the original order.
几 When the previous companies were talking about the solution, Liu Fan listened very carefully. Now Liu Fan has a desire to learn the knowledge of the artificial intelligence industry.
I listened to several plans one after another. Zhao Jianguo and others did not express any opinions, just listened patiently. And after seeing everyone's plan, Liu Fan became more and more aware of the importance of algorithms. Now it is difficult for artificial intelligence to break through in various fields. The core problem is indeed algorithms.
现在 The current development of hardware is still remarkable. Six of the nine companies in front of Liu Fan mentioned the innovation of hardware.
After more than two hours of relatively high intensity, finally Liu Fan's turn.
Each company has only 15 minutes to submit a proposal, which basically means to clarify its own product characteristics, product advantages, and then simply demonstrate it.
凡 Liu Fan and Sun Xia came to power together, Sun Xia simply said a few idioms. This proposal is nominally Huawei, so Sun Xia must say a few words. Liu Fan didn't mind, this was originally a mutually beneficial business cooperation, and anyone who wanted to eat alone was foolish.
After Sun Xia finished speaking, she stepped down. Liu Fan went to the speaker position and opened her PPT to adjust her status.
"Hello everyone, my name is Liu Fan, I am very happy to be able to propose with so many industry predecessors ..." Liu Fan casually set a few words and then entered the topic, "I want to show you our technology usage first And then technology. "
Liu Fan said, opened a video. The video is a relatively simple interface with an input box and an output box. You can see a photo of Sun Xia's life in the input box on the left, and then the photo of Sun Xia's ID card and the person in the output box appear on the right. information
After a while, the brightness of Sun Xia's photos was continuously lowered, but after each match, Sun Xia's ID photo and personal information still appeared on the right.
Further, Sun Xia's photos have undergone distortion, deformation, partial occlusion, etc., while the right side can still match Sun Xia's ID photo and personal information.
到 Until Sun Xia's face occlusion area reached 90% and after more than 20 random changes in coverage, the right side finally matched the identity card of another person, not Sun Xia.
Similarly, when doing distortion and other operations, there will be certain errors in matching after reaching a certain level, but this does not affect the shocked eyes of everyone present.
If the technology in the video really exists, its true accuracy is at least three to five times the highest level on the market today, no, it is higher, because many difficulties in face recognition are difficult to digitize.
It ’s like running 100 meters for 20 seconds and 10 seconds.
"Is the technology in the video already realized?" Some people in the audience couldn't help but whispered ~ EbookFREE.me ~ Although Liu Fan just said our technology use this sentence, it was still difficult to accept for a while and a half This fact.
"It should be just an idea." Someone whispered.
"What does it mean to show everyone a concept?"
"This thing is not realistic at all, and the features cannot be obtained. How can face recognition be achieved?"
More and more people are watching each other while watching each other, and among the eight people sitting on the stage, a few of them can't sit still. It seems that they want to let Liu Fan quickly turn off the video and tell everyone that this technology is implemented Anymore? But seeing Zhao Jianguo still sitting calmly, other people did not dare to take unauthorized actions. It can only be itchy.
凡 Liu Fan did not notice everyone's reaction, and continued to finish the video at his own pace. But after the video was finished, he turned around and saw everyone staring at him like a group of wolves.
Zhao Jianguo suddenly coughed consciously or unintentionally, and Liu Fan returned to his speech and quickly returned to the state of speech. "Due to the limited time, many special scenes have not been shown to everyone for a while. But I just believe that everyone has already faced us Recognition technology has a rough idea. "
"Did you really realize the technology just now?" Someone in the audience asked.
"Ok."
A simple and firm word hit the hearts of everyone present.
Zhao Jianguo, who had been sitting firmly as a pine, finally revealed an elusive light in his eyes.
凡 Liu Fan watched everyone ’s reaction, and kept telling himself to be calm. While maintaining emotional stability, Liu Fan continued to say, "Next, I will tell you about the technical concept ..."
