I am many years in the courtyard

Chapter 567, a call from the leader

Although smartphones were proposed many years ago, the technology was not realized by them.

But it seems that after many years, he is very proficient in using mobile phones, unlocking mobile phones, taking photos, testing related applications, etc., and asking about every detail.

It's as if he developed this phone, which is really jaw-dropping.

Anyway, after many years of operations, Xiao Yitang and the others were completely fooled.

After briefly testing this mobile phone, I was still quite surprised after many years. After all, it is now 1986, which is more than 20 years faster than the original time and space.

Of course, now the Apple mobile phone under his name has launched MP3 players and mobile phones that can take pictures. These are mobile phones that did not exist in the original time and space.

In other words, many years have completely changed the history of mobile phone development in the original time and space.

It's almost March now. Once March arrives, PHS will also release their new products.

Then it will be Huaxing Company again, and then Apple Company.

As long as the three companies are chasing each other and comparing technologies, the global mobile phone development process will become very different.

Secondly, the battery of the fruit phone itself also has a big problem. For example, in the original time and space history, when many people went to Harbin, the fruit phone actually shut down automatically due to low temperature.

As we all know, in the history of time and space, the signal problem of the fruit mobile phone produced by Apple in North America has always been a big problem.

Although face detection has a single category, it is not that simple. Posture, lighting, occlusion, and extremely small faces are all difficulties in face detection.

The R&D center on Heping Island and Pok Fu Lam Road has already developed sliding window scanning technology.

However, the leaders in these industries have also been in history. After a little splash, they were quickly beaten on the shore by the back waves.

It’s simply outrageous to open the door for outrageous things. It’s so outrageous.

Therefore, the smartphone that has been on hand for many years cannot actually be hidden for long.

From the face image to be registered to face detection, then to key point detection, then face alignment, then feature extraction, and finally the face feature database.

The essence of this idea is to use a simple weak classifier to quickly eliminate a large number of non-face windows in the early stage while ensuring a high recall rate. In the end, windows that can pass all levels of weak classifiers are considered to include faces.

Many years ago, he first praised Xiao Yitang and others, and then changed his tone and immediately talked about other things.

Historically, the batteries of fruit mobile phones used lithium batteries. In low-temperature environments, the electrolyte of lithium batteries may solidify, causing lithium ions to be unable to move normally into the graphite electrodes.

These technical points mentioned over the years need to be overcome one by one by Xiao Yitang and others.

This technology requires repeated scaling and scanning of images. There are many images obtained, and most of the windows are backgrounds. That is, the face is a sparse event. If the background image sub-window can be quickly excluded, it can greatly improve the performance. Target detection efficiency.

Therefore, face detection is the basic algorithm for face-related algorithms and engineering implementation.

Research on truly automated face recognition systems began in the 1960s.

In the 1870s, a Parisian policeman named Bédillon developed an anthropometric system based on human body characteristics, including some facial features.

Only by knowing clearly where the face of the detected subject is located can subsequent face-related tasks be carried out.

Based on the general object detection algorithm, face detection problems can be optimized in a targeted manner, such as anchor setting, background processing, suppression of false detections, etc.

By recording multiple sets of data such as head length, head width, middle finger length, ear length, height, sitting height, etc., and matching them with corresponding facial photos, criminals can be identified through comparison.

However, this all-manual method is time-consuming and labor-intensive, and the accuracy is not high. There is an urgent need for an automated and high-precision face recognition system.

In theory, all general object detection algorithms can be directly used for face detection, just change the output category.

Xiao Yitang and the others were immediately surprised when they heard the face recognition function mentioned for many years.

"There is also the face recognition function."

This gentleman believes that by the age of twenty, the skeleton will be basically finalized.

The bald eagle in this time and space already has early face detection algorithms, but it is still a very simple technology.

This technology is even more difficult, because if you want to realize this technology, you have to start talking about it a hundred years ago.

Face detection refers to accurately locating the position and size of a face in a given face image.

"Okay, okay, I like this phone very much. It's almost what I want. Especially the fingerprint unlocking function is wonderful. But I think it's not enough."

For example, the Bald Eagle algorithm uses template matching technology, which uses a face template image to match each position in the detected image to determine whether there is a face at this position.

When the battery temperature is too low, in order to prevent excessive discharge, the phone may automatically shut down to protect the battery.

There was even Motorola earlier, which was the originator of mobile phones.

In addition, after the convolutional neural network technology achieved success in image classification problems, it was quickly used for face detection.

Many years after the launch of Peace Island in the 1960s, development projects in related technologies such as computer technology and optical imaging technology have been launched.

Therefore, it is normal for the fruit phone's throne to be killed.

Anyway, in the history of time and space, fruit mobile phones have always been beaten by domestic mobile phones.

Logically speaking, this should not happen, but it is a pity that Nokia also dominated the world back then and was the well-deserved king.

The signal problem of fruit mobile phones is even more outrageous.

General object detection considers a wider range of general objects, with complex and changeable scenes. The shape, background, size, etc. of the objects are more complex than a single category such as a human face.

Therefore, cascade classifiers such as AdaBoost are used for face detection.

The most important thing about the entire automatic facial recognition system technology is the facial feature database.

For example, battery life and mobile phone battery life at low temperatures, and the most important thing is the signal!

These technologies have not been very clear for many years, so scientific researchers like Xiao Yitang almost always follow the steps and take their time.

It is precisely because of this that Xiao Yitang and the others changed their faces so much after hearing for many years that the face recognition function should be added to mobile phones as a function to unlock the phone.

Just because face detection is still based on deep learning, it is not a very skilled face recognition technology.

Although this method of using convolutional networks for face detection surpasses the previous AdaBoost framework in accuracy, the technology is not yet very mature.

At the technical level, we have not been able to provide more help for many years, but we can provide financial and other support. "But I do have a small suggestion, that is, you can try to develop a more detailed graphics processor to establish a higher level of face detection algorithm technology."

Xiao Yitang and others expressed their understanding of the suggestions made over the years, but it is not yet certain whether such technology can be truly realized.

If such technology really exists, it will be widely used not only in mobile phones, but also in many fields such as national defense and police.

I stayed on Heping Island for two days, and for many years, in addition to checking my smartphone, I also checked my tablet.

In short, there are many electronic products, and these electronic products are the outlets of the future.

As long as one of these technologies is used, China Renaissance, Apple, and PHS can all take off.

Of course, products that are too transcendent will not be released directly for many years.

After all, the money that should be earned is not earned, which is not a good thing for other electronic products.

Not to mention, cross-generational electronic products mean that the upstream industry chain also needs large-scale upgrading.

If such electronic products suddenly appear without a relatively smooth transition period, it will also be a huge blow to the upstream industry chain.

As said, there won't be any surprise attacks for many years, so just squeeze out toothpaste.

For example, the mobile phone product launched by Apple in December had only a camera function of 300,000 pixels.

Seriously, what can 300,000 pixels do?

Even a mobile phone with a camera function of 300,000 pixels is still very impressive.

Therefore, such products are enough for Apple to make profits for several years.

Of course, this depends on whether PHS and Huaxing will engage in differentiated competition.

Anyway, no other mobile phone company has entered this track to compete with the three Apple companies, because their technology cannot compete.

There is no way. Whether it is the previous PHS company and Huaxing company, or the mobile phone with camera function launched by Apple in December last year, these technologies are updated and iterated very quickly.

It can be said that before consumers even react, the three companies have already launched more powerful mobile phones.

After leaving Heping Island, he returned to Hong Kong Island many years ago.

The investment project he told his leaders during the Spring Festival will now be officially launched.

Needless to say, mid- to low-end car projects are still very profitable, but the investment is also huge.

As the project spread, the cell phone that had been used for many years suddenly became noisy, even if it had not wanted to answer the phone for many years, it was still not enough.

For example, here in Baiyun City, the leader called directly. It has been difficult to refuse for many years.

After all, the other party has helped me for many years before, and the relationship is very good, so it’s hard to ignore the other party’s calls.

The status and status of a leader who has had a private mobile phone number for many years is naturally different.

"Many years ago, I heard that you invested in two big projects in Beijing."

On the other end of the phone, after a few pleasantries, the leader got straight to the point and got down to business.

"I heard that it is a car project and a motorcycle project, and the investment is huge."

"Although the capital is the heart of the country and is also your hometown, you can't favor one over the other. Our Baiyun City is located in the south, closer to Hong Kong Island."

The geographical location of Baiyun City is very advantageous.

Whether it is the import of raw materials or the export of automobiles, it has unmatched advantages for enterprises.

The most important thing is that there are no heavy industrial companies in Baiyun City at all, almost all of them are light industrial companies.

That is, several car brands under the Rolls-Royce Group have established factories in Baiyun City, but they are also labor-intensive industries and do not have core technologies.

It's not that I haven't been happy with each other for many years, but that I haven't wanted to expose this relationship easily for many years.

What's more, whether it's Rolls-Royce, or brands such as Bentley, Porsche, and Mercedes-Benz, they all take root on Hong Kong Island. The import of technical personnel, raw materials, and the export of automobiles are all here on Hong Kong Island. It's also more convenient.

Then Baiyun City is responsible for some relatively common production and assembly processes such as car screws and car frames.

Engine and other parts are basically produced on Hong Kong Island.

Therefore, the leaders of Baiyun City are quite dissatisfied with the practice of placing the two major projects of mid- to low-end cars and motorcycles in the capital for many years.

And also a little unconvinced.

What advantages can Beijing have?

Regarding this, I have been too lazy to argue with the leader for many years, so I just said:

"Leader, I don't intend to favor one over the other. It's like this. After the Lantern Festival, there will definitely be a super big project coming to Baiyun City. Whether you, leader, can handle it then depends on your sincerity."

After hearing what many years had said, the leaders of Baiyun City were immediately overjoyed, patted their chests and said:

"No problem. I promise to receive the distinguished guests well and be able to accommodate them. But it won't be many years. Can you tell me in advance what the project is so that I can be mentally prepared?"

"The leader is a factory related to automobile parts. It mainly produces gearboxes, rotating shafts, differentials and other parts, as well as automobile suspension system parts such as shock absorbers and steering beams."

As soon as the words "Many Years" came out, the leader suddenly took a breath of cold air.

These auto parts are all core technologies. If such a parts factory were to settle in Baiyun City, hiss!

Good guy!

That’s incredible!

"For many years, is it a spare part from Mercedes-Benz?"

The leader immediately asked cautiously.

Because it has been said for many years that it is a huge project, and these are just spare parts.

Since it was a spare part, but it was also a huge project, the one he could think of was Mercedes-Benz.

For example, the Mercedes-Benz E-Class sedan underwent a mid-term facelift in 1982. The most obvious change was that the entire series adopted rectangular headlights that were originally only available on the top models.

In addition, the new car also has optional ABS and driver airbag.

Its sales exceeded 800,000 units that year, and by 1986, global sales were close to 2.7 million units.

This sales performance is terrifying!
