Facial recognition How far away we are

Old sci-fi movies, usually like the huge space of spacecraft outside the grand scene, the earth people armed with lightsaber swagger, and in recent years, science fiction movies or large production of High-tech, seems to be closer to life, in which face recognition seems to be the necessary technology.

such as the popular American drama "Suspect tracking", tells the story of two attractive old men and a machine to predict the occurrence of evil. As the internet becomes more and more convenient, it also means that each of us has countless monitors and cameras, all of which make it difficult to escape surveillance on every street corridor. Large to transnational drug traffickers, small to litter confetti, because the function of face recognition will let all human behavior no secret.

Sci-Fi movies are a lot of the future of human projection, Star Trek is a classic, in addition to the plot, there is the ability to predict technology, whether mobile phones, tablets, Google glasses can be found in the film from 20 ago.

In fact, face recognition is no longer a science and technology in the reverie, but has been deep into all aspects of our lives.

What is face recognition

In the narrow sense, face recognition refers specifically to the technology and system of identifying or locating the face. But in fact, face recognition is a popular technique including face image acquisition, face location, face preprocessing, identity recognition, identity search and many other links.

Face recognition is actually one of the biometric recognition systems. Biological identification refers to the use of the characteristics of the organism itself to distinguish the individual organism. such as face, fingerprint, palm pattern (after the street fortune-teller can change the signs for the "senior scientists"), iris, retina, voice, behavior and other biological characteristics can be used to identify biological individuals.

To give a straightforward example, we have a lot of senior Island action film experts around, some of them may not be able to identify each AV actress face, but if these actresses do not wear clothes, they can often be familiar with the name. This is the biometric recognition system, the human face is only one of the branches. In addition, Japan also has a special entertainment program, touch the chest of people.

Two. Face Recognition advantages

The biggest advantage of face recognition is naturalness, because human interaction is the use of facial to distinguish others and identify identity. Fingerprint iris and other biometric identification accuracy rate is high, but for the first time to meet the men and women, you could just say, "You look like my dream Lover" or "you look exactly the same as my ex-girlfriend." You can't say, "Wow, your fingerprints are really sexy" or "beautiful, Can you come over a little bit? I want to remember your iris! "

Another big advantage is the difficulty of perceiving. If it's fingerprint recognition, you need to grab her hand tightly and press the position sensor for the red scan. If it's a retinal scan, then you need to hold her head, like an ophthalmologist in the optician's eye, and keep her eyes on the mysterious window. Compared to these recognition techniques, facial recognition is very secretive, you can quietly hide in the crowd, open the camera, see the right girl, far from her gently sweeping, see the mobile phone screen flashing a few green characters "big wave Zombie Come, master run!"

Three. Face Recognition algorithm

The development of face recognition, like China's lake and foreign parliamentary system, has different schools of algorithm. At present, it is widely used in computer image processing technology to extract portrait feature points from human face, and then use the principle of biostatistics to analyze the resume mathematical model, that is, the face feature template, and then compared with the information stored in the database, to judge whether it is the same person by similarity value.

That sounds like a mystery to me. In fact, someone may be the same as your frog eye, or someone like you have the same Eagle hook nose, there may be someone with your same double chin, but can be so many characteristics of the disorder group together, it is not you.

This article does not repeat the algorithm too much, so as not to expose their ignorance, more let you know, most people face recognition is based on the face of different points from the template to identify. Facebook acquired the face.com before, using the face recognition technology is to extract more than 80 features from the face to form a histogram, accuracy can be distinguished from identical twins. Those martial arts fictions, such as the beard and other easy to tolerate surgery is basically ineffective, but whether Facebook can tell Miss South Korea, I still have doubts.

Four. Face Recognition application

1. Face pay

The Finnish company that founded only half a year uniqul let a lot of people's dream become the reality, that is "brush face consumption". Now it's just a trial run in Helsinki, Finland, but it's not a good idea. I only use standing in front of vending machine, it lightly looked at me one eye, on the spit out a box of Tang chef braised beef noodles. And a woman with long hair fluttering body with a portly father, the machine lightly swept a glance, spit out a LV bag plus a kind reminder, "God-Father has for you to spend 134722 yuan, more than the national 35% Guo Beauty." ”

2. Movie Character recognition

Are you still upset about not knowing the characters in the movie? Are you still sorry for not knowing the bikini girl that flashed in the movie? So Google's movies and TV mobile apps for Android tablet users have to be used, and this program can be used to watch movies and TV When you see the character you are interested in, you can press the pause button at any time, and your name/information/previous work/social media dynamics will appear. Unfortunately, the service is only limited to the United States, and the support of the film around 1000.

Strong demand for the domestic team can shanzhai this technology, especially when I see the Thunder play, can let me press pause, to his micro-Bo Spit. In addition to watching love action movies, we can press pause, to sincerely praise the people of the artist's dedication and superb acting.

3. Attendance System

For face recognition technology, the most recent application is the attendance system. After all, the cost of the violation is lower, but the use of face recognition, do not want to go to work, it is necessary to do a according to their own five-facial features 1:1 than the copy of the face silicone model affixed to a inflatable doll, the inflatable doll also needs to have 37 degrees of normal human problems. Also need to find a willing to hold a inflatable doll to the company not afraid of ridicule true love, can do these people, do you still need to work attendance?

In China, the application of the face recognition technology to the ground gas is Baidu's "PK Star Face", that a period of time, whether micro-bo or micro-letter, are this Zhang Zhang narcissistic cheeks occupy.

Embrace the application behind the face recognition technology curiosity, Xiao to the emotion of the reason, let a certain Baidu insiders understand an open internet world needs you me his common efforts, promised to meet with me.

Did not expect to understand the "PK star face", but no intention to see another system, "Baidu Mobile office platform" Face login function.

He immediately shut down the system, as if afraid I pulled out AK-47, holding the phone to force him to smile at the camera to login intranet.

I had to smile and said: "If I catch a sister of your Baidu, locked in a dark damp basement, let her call every day not to seek the Earth, only she is a person ..." I sit opposite me he has been completely attracted to the story, a look of the wretched and looking forward to say: "Then?

"I fed her a chocolate burger every day, did you say that your facial recognition system would recognize her a year later?"

He said he would go back and find a sister who was willing to cooperate. And then there was no more.

Five. Face recognition without the integrity of the application of reverie

The following words are all for the author of No moral reverie, declined all the guard acrimony attack.

1. Facial recognition on erotic items

Now the domestic market for erotic goods or industrial production, is all the volume of cottage factories of goods production. This reality makes a lot of the pursuit of life, literary youth can not accept, inflatable doll is not a personal custom? How can a massage stick be so mediocre that there is not even a Mao poem on it?

and add facial recognition function, each of the erotic products are given life, they have spirituality, know their own masters. When it found that the hand-held massage wand was not his dearest mistress, it was no hesitation to initiate an "autonomous attack" program, such as increasing the vibration frequency by 100 times times and adding a discharge function. When the inflatable doll found himself on the person is not their favorite cock silk male master, rather guns's instructions let it rise to counterattack, first to 100 times the monkeys steal peach.

At the same time, this technology can obviously improve the Chinese foreplay problem, according to the owner of the previous sex frequency, duration, peak time combined with the partner's various combat indices to draw conclusions, how long to open the switch on the sex goods. (not only face recognition, but also large data and cloud computing)

2. Distinguish animals

In a lot of film and television dramas, we can always see Meng sister hurt through the heart, a runny nose a tear in the rainstorm shouted: "XXX, you beast!"

So with the face recognition, Meng sister only to come to the accosted man gently sweep, you can see all his information and emotional experience, and then choose whether to continue to contact.

Of course, if you are willing to pay, it can be as soon as the popularity of the network of the little movie wearing Google Glasses, you can directly query his bed on the battle index.

3. Rogue distribution Map

Face recognition technology if combined with the street-wide monitor, in the system operation ability to achieve, completely can out a rogue distribution map for users to use. You can also choose whether to "avoid the rogue" when navigating the car.

Of course, if you have no enthusiasm for life, feel the time of despair, you can also in dark late at night, holding the mobile phone, according to the map step-by-step direction of the female rogue gathered place.

At this time, we have to shout "beast, let go of that rascal!"

Summary

"Chun Jiao and Zhi Ming", there has been a sentence to make people laugh in the lines of Tears "people this lifetime so long, who did not fall in love with a few scum." ”

But if the face recognition system can be popularized, we can let scum hide, and then happily play dead scum.

But there's a problem, I've been thinking about it for decades and I haven't figured it out.

Why is no lover scum always have a girlfriend?

This problem, I am afraid to rely on face recognition technology can not be solved.
