In addition, Apple also announced that it will be held next Monday to push iOS push the 8.1 release, Apple Pay service will be officially launched on the same day, which new signing 500 Cooperative Bank, and support, including Sephora, Starbucks, more businesses.

iPad Air 2

And last-generation iPad Air the biggest difference is that due to the iPad Air 2 completely eliminates the air layer in the middle of the screen, not only significantly reduced screen glare, also to reduce the thickness of the 6.1mm–18% lower thickness than the previous generation, is the world’s thinnest flat-screen computers. In addition, the iPad Air 2 also as rumored joined local gold color scheme, and is equipped with a Touch ID fingerprint identification technology, and support for Apple Pay.

Apple Chinese website then update a page, iPad price for Air 2 rows 16GB 3588, 64GB, 4288, 128GB 4988, Apple stores in China now only Wlan models on the shelves, currently there are no online 4G cellular network.

iPad Mini 3

In contrast, the iPad Mini 3 upgrades did not stand out, but added a Touch ID fingerprint technology and support for Apple Pay, as well as the same color scheme for local gold.

IPad Mini 3 sold for 16GB $399, 64GB $499, 128GB, $599, 4G cellular network Edition respectively, at 529, 629 and $729. On October 17 a reservation.

Kingdom, iPad mini 3 16GB-2888, 64GB 3588, 128GB 4288. And the iPad Air 2, Kingdom temporarily not 4G cellular-network version of the message. (It is worth mentioning that, since there is no built-in NFC chip, iPad and iPad Air 2 Mini 3 support in-app purchases only, not shopping at the store. )

The new iMac and Mac mini

Almost nothing due to the iPad, the new iMac is probably the biggest surprise in this show, because the new iMac screen resolution at an impressive level of 5K, 67% more than 4K pixels, only the thinnest of 5mm, there are optional and only 27 inches, sold for $2499, about 15,300 yuan.

New iMac new iMac mini, again on October 17 and taking orders.

Awkward iPad

This may be the successive launches of Apple in the shortest period of time, much of the information also suffered exposure before then, but we can still gain a surprise, especially the iPad Air 3 and the new iMac has shown once again strong in industrial design of Apple’s strengths and accomplishments.

But we also see that really makes the Apple iPad business headaches, even apples in processor and camera resolution, and some of the features are tied the iPhone after 6, it still seems so unobtrusive. In fact, many users for attention on Apple’s new iPad interest inertia, rather than real purchase intention, because the iPad’s major markets and consumers are facing a saturated, and the replacement of the old user enthusiasm is not high.

This is not the iPad for the first time that I felt ridiculous “durable” does become a problem on the iPad upgrades, plus most people don’t carry it out, or use it as a productivity tool, so entertaining that iPad is a large number of mining at the same time, the attraction becomes relatively simple, end user will long stick to one device, rather than replaced.

In this regard, Tim Cook, have two strings to one’s bow, is working with IBM, to help them to the enterprise market iPad, and the other is working on big-screen iPad, which will be launched some time next year. But Apple may need to accept reality, iPad Mini up and down very quickly, and it was reduced to a mass experience started with iOS eco-equipment–before that, most people choose the iPod Touch as the Apple eco-ticket.

And big-screen iPad, now seems inevitable and even the Macbook was competitive because the screen after the increase, an iPad that Apple will add more functions, but limited usage scenarios, and the crowd, so promotion of productivity will be the key. Although its product with the Macbook hard on the morphological and ecological barriers, but the Tablet and notebook only a keyboard away, has become increasingly like iOS and OS x now, Apple will make the choice of how clearly are the most interesting to watch.

Cakes is the Mid-Autumn Festival will eat the cake, sweet-smelling, shiny bright, holding in their hands to say a happy. When I see printed with a decorative variety of moon cakes, are you wondering how these lines are printed on the Moon? Wonder how the complex printing technology come from? Private moon cake mold usually wooden, and du Li Mu. Du, Lei Muk Shue, also known as the “Du Mu”, fine wood and unimposing, anyway, the texture is not very different, suitable for engraving, except for the production of moon cake mold, but more widely used for carved furniture, and seal. Moon cake mold now long out of our lives. It is becoming an increasingly rare exquisite collection at the same time, also became China’s thousand-year cultural inheritance and testimony of Mid-Autumn Festival.

Making Cantonese-style moon cakes

“Moon cake mold” in Henan is common. In “Moon” in the months before, some merchants and Mills started marketing “moon cake mold”, individuals or businesses according to their own preferences, busy selecting or assessing a wide range of “moon cake mold”, the scene was very lively. “Moon cake mold” for better or worse, directly affects the production and sale of moon cakes. Master engraving of the “moon cake mold” is more popular. Late the Kaifeng old Bai Shoucai old, Central Plains region is engraved “moon cake mold”, the famous expert, enjoys a high prestige in the industry and his “moon cake mold” is often in short supply. It is understood that the old man of the industry introduced, engraving is a traditional “moon cake mold”, also needs more skilled master for a day or two’s time.

From conception to finish, from knives to techniques are really nice. Must first select solid and durable wood, such as jujube wood, pear wood and so on. Because these wood wood lines slender, and board surface smooth, and easy carved and easily cracking, not only easy save, and durable, so, “selected material” of bad, on “cakes die” of quality up with decided role; wood selected good yihou, first will wood saw into a block about 20 cm thick of blank, then, according to prior plans good of cakes styling, with knife carved out preliminary profile, that commonly known as of “prescribing” process; “playing side teeth” is on “cakes die” for carved of first step, that in “cakes die” Around engraving out arranged neatly of pattern of a process, this road process not only can enhanced cakes of decorative sex, more important of role is easy cakes smooth from “cakes die”, so most “cakes die” are to “playing side teeth”; “playing side teeth” completed Hou, Xia a process that finishing touch of lift, General are by master personally fencing, fine carved fine cut. Cake front all by this process, and the process is the “moon cake mold” key process from conception of the embodiment of engraving skills of the show, all is at stake.

View wood years die every year tasting cakes

Cookie-commonly known as the ringer, is the production of moon cake and pie-making tool. Some places make ringer has a history of hundreds of years, residents inherited grandfather carved cakes mold technology, bow in his father’s footsteps, deliberate engraving, decided to make one’s fortune. At that time, most of the cakes were produced with a cake mold. In the Mid-Autumn Festival approaching, this night, Mr Wang in China, Tianjin Academy of social sciences collections is our part of the cake show, as the national food culture, so the majority of users learn the story behind the moon cake production process, and people of Tianjin Windows give you a holiday gift.

Henan moon cake mold introduced, moon cake mold picture

Manufacturing moon cake mold has five processes. The first operation is to choose good wood, it is best to use pear wood, it features plate surface is smooth, fine texture. Selected PEAR Wood sawn into pieces of about ten centimetres thick square template, then drill lathe will dig a hole three or four centimeters deep in the middle. Digging the next step is the most difficult process model making moon cakes, is also the most time-consuming process. Because you must use the carving knife is a knife is a knife, chisel, round holes carved flat smooth can be used.

Side flower “teeth”! This is the next process, none of the cakes with chrysanthemum-shaped edge. Then pump the next process is the eyes, eyelets are moon cake mold vents, primarily for stuffing lay inside when air can be discharged.

Is making cakes for the last operation mode of “quintessence” features: carved, for the moon cake mold “tattoo”. Moon cake mold pattern has some content and form, and subject people, animals and floral patterns, together with the text. Moon cake mold, such as last name, store, and also said the words good luck. Carving knife requires concise, vigorous, feed the fast and deep. Up cake die-request printed clear, uniform, smooth face, stripping quick, easy operation, suitable for production.

Henan moon cake mold introduced, moon cake mold picture

Use the carving knife is also very particular about, are carved according to the need of self polishing of. Edge is flat, curved, narrow width, style, carving every different patterns using different carving knives. Local said a carved, carved complex patterns, using hundreds of different carving knives. Engraving tool needs regular polishing, sharp carving knife carved pattern is angular, and third dimension.

Custom-made cakes model bakery, hotel, moon cake mold in addition to cake outside the household production, urban and rural households are using. Therefore, wooden moon cake mold have a wide market. Today, many local residents are engaged in moon cake mold processing.

With the development of society, traditional cake mold ceased to its former glory, shoe cakes is idle and become a treasured collectors. In General, wood-mode because of its practical effect, so its Groove not too complicated and delicate, so moon cakes out of the die cannot; but there are also carving fine mold survived, presumably die-master made for viewing. Belief in line with folk customs and festivals, moon cake mold patterns usually have a certain standard, however, engraving master still has its space to show the creativity and skill of the individual. Moon cakes are square and round two in the North, most decorations were Phoenix pattern, take the meaning of Phoenix and melody, of course, hit big double happiness was indispensable in the.

Moon cake mold is combining life and art into a traditional craft. This process with the decline of traditional pastry has a dying trend, cherish the memory of the past, cannot help but lament the wheel of time is merciless, how to continue this memory of aromatic, would not seem to be just the collector’s responsibility, hoping people systematically organized and maintained, to leave the next generation to understand the older generation life opportunities.

Moon cake mold history

Moon cake Festival food, its text and logo reflect the rich cultural connotations, a carved cake mold called folk crafts. Cakes with a recorded history of the Northern Song dynasty, Su Dongpo’s poem “small bread, such as chewing, mystery and crisp.” Therefore, the history of moon cake mold seems to date back to the Song dynasty. Multimillion moon cake mold, more common is the product of the Ming and Qing dynasties, which may have a certain relationship with the durability of the material. Private moon cake mold usually wooden, and du Li Mu. Du, Lei Muk Shue, also called “Du Mu”, fine wood and unimposing, anyway, the texture is not very different, suitable for engraving, except for the production of moon cake mold, but more widely used for carved furniture, and seal.

Why I chose this video open source perspective MR glasses

Why I chose this video open source perspective MR glasses

Lei feng’s network: the author, Ai Tao, easy Apple CTO, graduated in computer engineering from the University of Toronto. For many years following the “father of the world wearable computers,” Professor Steve Mann, the basic research focus on the smart glasses. Recently, Apple’s core product VMG-PROV announces open source geeks, this video perspective of mediated reality glasses, why hasn’t officially launched open source? Why choose video perspective? Author to his personal experience to answer the question-“when we call VMG-PROV after the open source, we hope to expose all the problems there are products. “With the exception of talk about the pros and cons of the product itself, this is a serious article.

Following is the author bio, Lei feng’s network (search for “Lei feng’s network”, public interest) do not adjust the intent of editing.

Today I write a small article about VMG-PROV (the so-called open source geek Edition) what exactly is a thing, friends of hope reading this thing is going to take it in hand to yourself “toys” have some knowledge. Of course, the local casual, I think VMG-RPOV stand home are pretty smart.

| A source of blood

Remember me to mentor Steve Mann’s lab, see a costume freak engineers (including one with no tops hair man) is a pile of “destroying the old” electronic devices, monitors, and surrounded by various electronic components, while they are using the interface quite Chueh-Li’s unknown alternative program to do some things. That Flash was excited at the same time, also felt a little embarrassed for their ignorance.

Why I chose this video open source perspective MR glasses?

“Hi Steve, what software are they using?” With curiosity I asked, feeling weak burst.

“Oh Arkin, I can’t answer that if it’s not the right question.” Professor no shoes, with a soldering iron in hand, head back to me said. Maybe he doesn’t know I’m petrochemical.

“You know, Arkin, we don’t use any software in this Lab.” Professor down the iron, looking over towards me.

“Software are programs that you need to pay. Paying for software that you can’t hack or share is ridiculous.” Professor suddenly serious again. But I also understand why these programs are so strange.

I nodded, muses: “So everything here is open-source? Like everything?”

Professor smiled and nodded, “said Yes,Everything.”

Why I chose this video open source perspective MR glasses?

This time working in the lab, I was exposed to a wide variety of open source tools. Professor said was true, in the laboratory, our operating system is Ubuntu instead of Windows or MacOS; image editing or Photoshop instead of GIMP; even programs like Word and Excel, we used LibreOffice instead. Is more exaggerated, as researchers, we don’t have Matlab, but using a thing called Octave.

Steve used to be a work of art, in the collection now at the Austin Museum of art. In the figure below Installation called “License To Sit” is a License can only be used to pay for the Chair. Just like paid software, this Chair will quickly remind you to pay when due, otherwise, once expired, eject pin and forcibly stopped the Chair can provide you “sit” service. This work of art is fun, can make us think when rules are used in the digital world to some funny situations in the physical world.

Why I chose this video open source perspective MR glasses?

Looking at the Chair, remembers the first time he met Professor of that conversation, I suddenly realized a long consideration decided to actually have sources, depicting all had full blood of open source.

| Sent to the geek’s hands

Recently, we decided to make our own inadequate engineering VMG-PROV as an open source hardware and dropped it into the market in the past.

The move, in my opinion, there are contributing factors there are selfish reasons.

We really solved the problem of some smart glasses. The aims of open source, I hope fellow and aspiring geek by dismantling the VMG-PROV studies, could not repeat to solve these issues. The wheel here, do not need to reinvent it. In addition, we do the smart glasses are different from VR/AR, slightly ahead of the point. In order to make the ideal products as soon as possible, small teams of 20 people we need more capable of helping. When we call VMG-PROV after the open source, we hope to expose all the problems there are products. While geeks have jointly pointing to perfecting this product and we stand on the same starting line. Open source will be the future direction of development of science and technology, a geek of some accomplishments should not think about how it’s not perfect “little secrets” to make money, ought to be thinking about how to get people involved get things done as soon as possible.

Why I chose this video open source perspective MR glasses?

We hope to VMG-PROV is delivered to the right hands, this means that this product is not a consumer-level, or even the developer level, we call it a “geek”. We want to sell him to have open source blood, wanted to explore the digital vision, and have the capability of geeks. See here, I think readers should buy the VMG-PROV already had some little judge.

| Why choose video perspective?

VMG (included in the pre-PROV and MARK two version in development) is an open source, is a find mediated reality (and digital Visual) tools. We believe that virtual reality (VR) and augmented reality (AR) is a reflection of digital vision. Therefore, VMG first VR/AR video fluoroscopy can be compatible in a head at the same time. Wrote an article about the smart glasses before little article also mentioned that the AR time, mixed reality (Mixed Reality) or mediated reality (Mediated Reality), the video perspective is necessary to cross a threshold.

I am often asked, optical perspective programme in the market so much, and everyone was doing optical perspective, why did you have to select the video perspective? I said, I did not choose the video perspective video perspective of chose me.

Before entering the lab I majored in FPGA, and because of this, Steve let me use FPGA to conquer some GPU can’t run on the smart glasses algorithm, results, a senior and I present our findings on the SIGGRAPH exhibition. In the human brain explosion on the show, I chat with seniors in each identified future research directions. After returning to the lab, I mainly make video perspective and related software, and he began to study the optical perspective of things. Video perspective (Video See-Through, or VST) and optical perspective like HoloLens (Optical See-Through or OST), each with advantages and disadvantages. Now, I in AR applications, for example, probably sum up the two main problems. (Academia about the comparison between very thorough, we are interested to read the relevant papers. )

Why I chose this video open source perspective MR glasses?

Video perspective (Video See-Through, or VST) and optical perspective like HoloLens (Optical See-Through or OST)–

1, on the overlay and display view (VST victory)

Optical see through a special design will be projected onto a translucent digital screen on the display device, so show the occlusion effect (Occlusion) is not perfect. See Magic Leap earlier issued a patent for glasses you know, they spend at least 7 pages of content describing the complexity of their optical path design to reduce the occlusion. Optical see optical design is complex and would like to make a small angle effect there. Try HoloLens people (about 40 degrees) will be able to feel the small is a perspective that I feel.

Also, because of the complex design and processing difficulties, OST of the cost will be very high. However, translucent is translucent, you slow down, it is impossible to solve. In this connection, the VST win OST. View of the collection of pictures through the camera, digitized before it is displayed to the screen, blocking effect can relax at a low cost to be perfect. In this regard, VST can use algorithms to make real-time p, let the reality into your palette.

2, about the real picture delay and distortion (OST victory)

Due to the use of the camera, plus computers need to handle display and digital content, VST delay larger than the OST.

VST hardware like VR, camera and display refresh delay is congenital. On the OST, the real picture is the outside world through optical devices through inherent zero-delay and zero distortion. Video perspective in addition to refresh delay also needs correction because the position of the camera and optics and screen gap caused people like, nature will be delayed. We spend a lot of time, through the optimization of hardware and software to reduce latency. But the delay is never zero, in this connection, the OST out explosive VST. FENDI iPhone 6 Plus Case

3, on the VAC problem (tie)

Both OST and VST, VAC problems exist. This is what we use to display, depth perception mechanism in my eyes (Vergence) and monocular (Accommodation) when there is a conflict causing dizziness problem.

Interested readers can check out Vergence Accommodation Conflict or “vergence conflict.”

(Lei Feng network Note: VAC, you can view this analysis article the VAC has plagued virtual reality, is really no solution to it? 》)

Magic in the big Leap, this issue was also slowed by light field described a large number of technologies. In their prior to shipment, in this issue, current OST and VST, neck and neck.

| Geeks read on

VMG-PROV as a video perspective exploration tools, performance is limited. I hope the next description for you geeks recognize the risk of purchase PROV.

Delay in the VMG-MARK framework has greatly improved, and finally I will tell you details. Below is a screenshot from our Demo to be released open source project, a digital model can be superimposed on the desktop without preset Marker.

Why I chose this video open source perspective MR glasses?

In the open source Demo, VMG-PROV through binocular cameras capture the real scenes in, after processing by the FPGA on the head, through the USB3. 0 interface on the transmission to the connected PC. Real scenes by software calibration, Visual SLAM algorithm starts operation, digital model will default to the correct location. And then transmitted through the HDMI screen display on the screen at the end. This open source project contains:

1.VMG-PROV hardware detail and schematic diagram

As shown in the following illustration, VMG-PROV hardware parameters have been marked and are listed in the following table. Camera video footage collected through FPGA processing incoming in the connected PC, finally SLAM the superposition eye back in the digital model of the picture. So when used on the AR, VMG-PROV PC complete larger video stimulation, so it is recommended using high desktop distribution.

Why I chose this video open source perspective MR glasses?

As an MR head and VMG-PROV parameters can only reach VR entry level. I think to make a stunning application on the MR, this generation was not enough. That is why I hope we can take this as a learning and exploration tools, and also through your feedback to us more suggestions for improvement. In order to make this possible, we will provide a VMG-PROV diagram.

2. on the FPGA image processing hardware description language

VST is superior to the OST key point is the picture of reality changes, simply put, is through the algorithm, p.

In testing out the software algorithms to FPGA implementations or accelerated reduction of the delay is of great help. In our open source projects, contains a Demo of MR, synthesis and real-time high dynamic range image mapping (Real-Time HDR Composition and Tonal Mapping), exclusively through the logic into the FPGA inside.

The following figure, high-speed conversion exposure in FPGA control Sensor, and synthesizer to select from dark to light the best part of each picture.

Why I chose this video open source perspective MR glasses?

 FPGA is a magical chip is a chip in the transformer. FPGA engineer knows, FPGA not everyone got.

Below we are going to open source projects is given in the FPGA hardware description language in parts. Raw data from the Sensor came in would be completely ISP processing in FPGA, HDR synthesis after the USB3.0 to PC. I believe the project open source Verilog HDL, can attract members had the courage to master to join the chip-level exploration of MR. By FPGA combined with demand on the PC side, further reduce the delay VST.

Why I chose this video open source perspective MR glasses?

3. based on the PTAM binocular SLAM source code

VMG-PROV the SLAM is based on binocular RGB camera, was changed by the famous PTAM. This works above Miku stack the glasses in a video picture. PTAM then, we will knock sensor data fusion, and using different methods (such as ORB-SLAM or LSD-SLAM) to achieve more stable stacking. I don’t SLAM this drawing, including open source content, calibration of binocular camera correction, FAST feature extraction, RANSAC and Bundle Adjustment, and the model of Miku. Need to use Unity3D friends, the project also has to import the SLAM. Also, when we went to see the source code, you can reference PTAM information modified.

Why I chose this video open source perspective MR glasses?

| Ordinary developers wait

At this point, I think we need to do not need to purchase the “geek” has a certain amount of judgment. Since VMG-PROV has not reached the level, you want to do in VMG application needs to wait VMG-MARK (developer version). At the current pace, our research and development teams are VMG-MARK most of the technical problems have been resolved. Our hardware and software architecture is called VMG-MARK VLLV (Very Low Latency Video See-Through), it will delay video perspective problems greatly slowed (slow is not the solution, solution is Zero Latency). Therefore, I hope that a landing application developers the best use the product MARK, rather than a VMG-PROV geek version.

FENDI iPhone 6 Plus Case

The schema below is VMG-MARK, initially was designed to reduce the amount of video throughput calculation of PC demand, high real scenes of lofty frame streaming video directly from the Sensor into the screen, without a computer. Zhihou, slowly evolved into four modes.

Why I chose this video open source perspective MR glasses?

We call this framework VT Architecture, its four operating modes are:

1.Hard mode

Real footage of the video signals processed by FPGA and ASIC, then immediately hit the screen. This path delay minimum, but the most difficult. Write FPGA is not difficult, is courage.

2.Hybrid mode

This path is ideal for developing AR applications.

As shown in the figure, head of FPGA based on needs on the streaming video to connect on the PC, and then, through FPGA digital model of information fusion attitude to the original high-definition picture. In this way, we can greatly reduce the delay of real scenes, but also most of the computing resources that need to save, thus reducing your computer’s configuration requirements.

3.Soft mode

Attentive readers have discovered that this path is the path of VMG-PROV. This path is the most powerful, but extended to the highest. Video streaming through FPGA/ASIC and then into the computer, and finally after the screen is displayed. Soft mode suitable for early verification and experiment, written out by Soft optimization of the project according to the application requirements, and in other modes to achieve. Fendi

4.Light mode

Light patterns are well understood, is the VR head with Visual SLAM. Camera, though not in the front of the imaging, but the time to detect the Translational motion of the head, and test methods within the Lighthouse from the outside are not the same. We continued the development of better SLAM will also open source, I hope you wait a bit longer.

Wrote it, is about it. As a small team, we want to be your dream of geeks. I believe that sharing our many spirits, spirit, heart, ability, and to support our people.  We would like to share their work with such people, this is the most important reason we’re going open source.

Upgrade any sound quality headphones BoomStick sound magician

Listen to music, we’d like to hear the highest quality sound, we might have “money” to buy a good pair of headphones. However, to pick out a good quality, and overall fashion headphones is the need to take the time and effort. Now a company called BoomCloud 360 startup has developed a name for “BoomStick” product, which sells for $ 99 (about 645) device can be connected with any headphones, and the company developed algorithm to improve headset sound quality.

Upgrade any sound quality headphones BoomStick sound magician

“We are now trying to solve the sound problem. If you open the CD in the car listening to the song, relying on 4 or 8 speakers, will bring you stunning sound effects. However, if you are on the phone to listen to Spotify songs, the experience would have been much worse. “Founder of BoomCloud 360 qiaozhi·apulin (George Appling) said he thinks many people choose headset is focused on comfort, rather than sound quality.

BoomStick using up also very convenient, it is a size smaller, and weight more light of round angle cuboid equipment, built-in a can charging battery (once full electric can using 14 hours), user just to will headphones plug in BoomStick Shang, another a plug in phone, and flat or computer Shang, again by about BoomStick Middle round button, on can listening to music, video and network broadcast.

In fact, BoomStick is a bit like CD player, “bass boost” buttons, or a cheap portable DACs, sound not only can be magnified, and you hear the sound even more “meticulous”. Aplin said, the CTO of the company ailun·kelaimo (Alan Kraemer) prepared by the algorithm, who previously worked at SRS Labs for several years at a time, and SRS Labs has developed a very similar product a few years ago. Hello Kitty iPad

Aplin said Kramer and he developed algorithms to enhance engineers from different sources and the audio quality of any phone.

The sound quality is actually a very subjective judgement of an audio equipment standards, and BoomStick. rely on algorithms to optimize the sound quality of different headphones.

BoomStick highlights the fact that it appears to make a piece of music of different musical instruments became more likely to be heard by the user. The device another “sell” is its “flexibility”, because it is not limited to any type of headphones and audio source.

In order to enable consumers to buy before the device experience, the company has reached an agreement with a major mobile telecom operators to cooperate, plan to show in which store BoomStick. In addition, users can also go to the company’s official online virtual experience BoomStick sound enhancement. Users can be given a few song choose a song, listen to and open a virtual version of the BoomStick off BoomStick listening to the same song, and compare the disparity between the two.

Despite the BoomStick is the company’s first product, but the company on this product has a lot of ambition, Aplin said: “headphones, speakers, car, live band, television, home computers, elevators, these can depend upon our algorithms make a better sound. ”

Baidu updated AI strategy: with AR, cut UAV project

According to media reports, the recent deep learning of Baidu Baidu in Artificial Intelligence Lab Director Lin Yuanqing also outlined the main research directions: deep learning platform, basic image recognition technology, fine-grained image recognition, video analysis, image recognition, AR technology and hospitals.

Basic image recognition technology in Baidu’s OCR (optical character recognition) technology greatly improved, including mobile phone identification accuracy rate of more than 99%. In addition, Baidu would next month, thin-grained image recognition feature applied in glutinous rice: when user dish picture, near Baidu algorithm to recommend to users within 5 km and the restaurant.

Although Baidu wide deep learning laboratory in artificial intelligence direction, but there are some vulnerable project, which cut off the outside world look on the drone program. Lin Yuanqing believes that market potential for unmanned, but Baidu’s perplexity is how they compete with large boundary.

UAV positioning and it is closely related to the use of cut scenes, middle of last year, Baidu Union billion airlines launched drone takeout service users in support of unmanned delivery takeout store orders, delivery staff in the App, enter the destination of the flight, unmanned aerial vehicles will send out into the hands of users. Drone takeout from the test up to now has been a year of service time, outsiders said, judging from the present conditions, the services belong to false needs, and costs are too high and too many factors beyond their control, and so on. Baidu also imagine using unmanned aircraft mapping remote areas map, but after analysis found that the market value is not significant.

AR technology is Baidu’s plays. When it comes to AR, Lin Yuanqing replied, “it’s definitely can make money.” Currently this market and there were no large industry leader in Xinjiang, leaving the Baidu space is very big. Earlier this month, Baidu DuSee,DuSee released a mobile AR platform computer vision and depth of what is learning to understand real-time image, the platform can be via a Smartphone hardware to “understand” real-world 3D environment, which causes the phone to generate images with real-world interactions. It is reported that DuSee can be used in interactive advertising, marketing, education, manufacturing, areas such as interior design, future they AR and speech recognition, and natural language processing technology combining.
