Photo face recognition software use case analysis

This article is mainly for the use of photo face recognition software use case analysis. In the past week, mobile phone friends have been frequently screened by photos with age and gender. These photos are from a face photo test age and gender. Entertainment software, the software exploded on the Internet within a week. Yesterday, the reporter learned that this "measurement age" software uses face recognition technology, the city's enterprises have started research and development test three years ago, "pure entertainment" "measurement age" software is just the technology The tip of the iceberg is huge, and its applications in the commercial, Internet finance and security protection are very broad.

"Testing Age" software online red

Open the how-old.net homepage with your phone or computer and a simple home page appears. Click the link to upload photos and select a photo to upload. After a few seconds, the person's face in the photo is marked with a yellow mark with the icon showing the gender and the age number. Based on the essence of "game", after each test, the website will attach a sentence: "If you do not measure your age and gender, we are very sorry." Microsoft's former global vice president Kai-fu Lee also uploaded photos of himself and his wife. The test results show that Li Kaifu’s test age is 68 years old, and his wife Xie Xianling is only 20 years old. He jokingly said: “I finally reached a wish, there is a wife who is 50 years younger than myself.” Although the age of the test is slightly different from the real age. There are differences, but many netizens share their "identification" results in a circle of friends, with a slogan "No matter whether it is true or not, young is happy, happiness will be young".

"Testing Age" software is purely entertainment

The reporter used the mobile phone to open the website and uploaded a photo of Huang Xiaoming and Angelababy. The 38-year-old Huang Xiaoming’s “identification” result was 26 years old, and the 24-year-old Angelababy “identified” was 20 years old. Subsequently, the reporter uploaded a photo of Sun Honglei’s recent visit to Qing Dynasty. The result of the “identification” was 44 years old, and his age was only one year old. It seems that this age-dependent software varies from person to person, and entertainment is much higher than practicality. According to reports, this site first appeared at the Microsoft Developer Conference on April 30th. According to Microsoft, the number of page views reached 35,000 in just a few hours after the release of HowOld.net. In fact, Microsoft's original intention is not to use the website to guess age and gender, but to provide an example for developers to show how to build a fun app with cloud services in a short time.

"Measurement age" is face recognition technology

Can you really recognize the age and gender of a person through a human face? Is this technology newly developed? Is this technology developed for entertainment? The reporter came to the Intelligence Institute of the State Key Laboratory of Digital Multimedia Technology yesterday and interviewed the face recognition technology expert. Walking into the intelligent office on Songling Road, there is a large screen with video at the entrance of the office area. When the reporter passes by, the image face on the screen becomes a Facebook, and the face changes with the change of the reporter's expression. Become a smile, cry face or normal face. The intelligent face recognition software designer Gao Weijie told reporters that this big screen is an entertainment application of face recognition technology. They want to improve the enthusiasm of employees through this "smile detection". “The face detection software that has recently been popular on the Internet is also an entertainment application of face recognition technology.” Gao Weijie told reporters that “pure age”, which is purely entertainment, is just the tip of the iceberg of the huge function of face recognition technology. The technology has broad prospects in business, internet finance and security protection.

"Artificial Intelligence" remembers millions of faces

Gao Weijie opened the face recognition system test interface of the intelligent office on the computer. The real-time image of the reporter's face appeared immediately in the interface, and the eyes, nose and mouth were covered by dozens of dots and straight lines. The age of the reporter's face test appears on the screen, and the test results are very close to the true age of the reporter. With the smile of the reporter's mouth, the test age will be reduced by one or two years due to a smile. Gao Weijie told reporters that their face recognition system has been developed for three years ago after long-term technical accumulation. "In fact, this is a kind of artificial intelligence that the machine learns autonomously. The various facial features input are the learning process." Gao Weijie said that after designing the algorithm of the artificial intelligence system, they collect face images of different ages, and match the images and images. When the age and gender are entered, the system will automatically generate nearly 100 key points based on the face, nose, mouth, wrinkles and other information of the face, and record the data. As the input data increases, the system becomes more and more "smart" and the recognition accuracy will become higher and higher. According to reports, the system will collect information of millions of people according to different age groups, and will collect about 100,000 images for each age group. After the smart system forms a gender or age model, when a photo is detected, the system compares it with the model to detect details such as the corners of the eyes, the corners of the mouth, the nose, and wrinkles to determine gender and age. Therefore, when the reporter smiles, the change of the corner of the mouth will lead to a difference of one or two years old.

Powerful face recognition

Gao Weijie told reporters that the application of face recognition technology is very extensive. It was first used for public security technical investigations, such as identifying suspects, and can lock the scope of suspects in surveillance images. In commercial applications, face recognition technology can also be used to count the gender, age and other characteristics of the population. For example, a shopping mall or a counter can use this system to analyze the gender and age of customers, form big data to provide merchants, accurately deliver goods according to the customer population, and even identify VIP members, and directly display the welcome name of the member name at the welcome party. Width. In the field of Internet finance, face recognition is equally important. Gao Weijie said that now the bank needs to bring an ID card to the business hall for processing. In the future, using face recognition technology, you can sit in front of the computer camera at home and realize remote account opening. The face recognition system of the home TV can also play TV programs according to the age of the person in front of the TV. If a minor is detected watching TV, the TV will automatically block the violence and blood. According to reports, this face recognition system will enter the use phase during the year.
