Pix4D Cloud Service Makes 3D Models from Aerial Photos

The Pix4D project can stitch together patchworks of photos, thereby generating three-dimensional (3D) models on the cheap, reports Smartertechnology..

“Cloud-based services are enabling fast, cheap, large-scale three-dimensional models of almost any landscape. The models are generated from easy-to-obtain aerial photos from drones—unmanned aerial vehicles.

The Pix4D cloud service accepts a stream of related photos from which it generates a 3D model in as little as 30 minutes. The service not only automatically generates the 3D maps, but also adds points of interest that can be cataloged by users. To demonstrate the service, Pix4D took 50,000 photos of its host city—Lausanne, Switzerland—and created the world’s highest-resolution 3D model of the city. The Pix4D user interface then allows users to navigate to any location in the city and view it from any orientation.”

Sigma SD1 Camera to Ship in Early June

46-megapixel DSLR creates new market for medium-format photographers

Sigma Corporation of America, announce that its flagship DSLR, the Sigma SD1, will be available for purchase for the MSRP of $9,700 in early June.

This 46-megapixel DSLR is delivered in a splash-proof, easy-to-handle build that is similar to that of a classic 35mm camera. Professional and high-end enthusiast photographers will utilize the SD1’s exclusive Foveon 23.5×15.7mm APS-C X3 direct image sensor to capture exceptionally rich and detailed images that have a film-like quality. Users will also benefit from Sigma’s wide selection of interchangeable lenses that are compatible with the SD1.

“The SD1 will carve out a new category in the marketplace by providing high-end photographers with an alternative to very expensive medium-format cameras and digital backs, while offering unrivaled image quality,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “By embracing the SD1, serious photographers will also be able to take advantage of Sigma’s extensive lineup of affordable lenses, which are compatible with this new camera. The selections of lenses for medium-format cameras on the market are somewhat limited, so this will be a huge advantage for SD1 users. This is undoubtedly a very special camera, and we’re thrilled to share it with the photo community.”

In addition to the 23.5×15.7mm APS-C X3 direct image sensor, the Sigma SD1 features dual “Three-layer Responsive Ultimate Engine (TRUE) II” image processing engines, which improves processing speed, provides high resolution power and produces high-definition images with richly graduated tones. It also allows simultaneous RAW and JPEG recording, which is a first for Sigma cameras. Additionally, the photographer has the option to select full-size, half-size or quarter-size RAW files making it a more versatile camera for a wide range of photographers. The Foveon sensor uses three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths. This technology efficiently reproduces color more accurately and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moiré is not generated, the use of a low-pass filter is not required.

The optical format of the Foveon sensor has been upgraded from that which was used in previous SD cameras, and has increased from 1.7x focal length to the 1.5x focal length multiplier. The SD1 also benefits from improved image processing and noise reduction algorithms, with an ISO sensitivity range from 100 to 6400. This is two full stops more sensitivity than the SD15, which has a maximum 1600 ISO. An intuitive user interface and an impressive lightweight, yet solid magnesium alloy body and O-ring sealing connections that make the camera durable and splash proof are also key feature upgrades of the flagship SD1.

The SD1 adopts the TYPE 1 Compact Flash Card, and is UDMA-compatible enabling fast processing of large amounts of data. The autofocus system features an 11-point shifted twin cross type sensor, which improves AF accuracy. The SD1 features a 3.0 inch TFT color monitor. This 460,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to check focusing and composition. The SD1 can be used with more than 40 Sigma SA mount lenses such as ultra-wide, ultra-telephoto, macro and fisheye.

Sigma’s image processing software, Photo Pro 5.0, comes bundled with the camera and its simple operation allows quick and easy capture of the desired imaged. Additional functions such as Loupe, Slideshow, Print, Convert to JPEG file and Batch White Balance settings are also incorporated into this software.

The Sigma SD1 will be available for the MSRP of $9,700 through select authorized Sigma dealers. For information about Sigma Corporation of America, visit www.sigmaphoto.com.

Mozilla Plans to Force Firefox 3.5 Upgrade

Mozilla plans to push 12 million users of Firefox 3.5 to a newer version next month by automatically upgrading their browser, according to PCWorld.

“While it will continue to “dangle the carrot” of Firefox 4 to those users — Mozilla started offering an upgrade to Firefox 4 to people running Firefox 3.5 and Firefox 3.6 last week — it will “force 3.6 on 3.5 stragglers not choosing to update to Firefox 4 or 3.6 (give them the stick),” wrote Christian Legnitto, the Firefox release manager, in a message posted to a developer mailing list .

Later, Legnitto said his choice of the word “force” was ill-advised, and noted that only Firefox 3.5 users who had left the default automatic updates setting enabled would be moved to Firefox 3.6 automatically.”

Bing Adds Facebook Recommendations

Bing Adds Facebook Recommendations to Search writes Edmund Lee on AdAgeDigital.

“The deal was initially announced in October, but since then Google has upped the ante by adding its own form of social recommendations to search results, including a “plus one” button that allows users to vote up pages in search results.

he updated service, which launches Tuesday, will incorporate data from the largest social network, which has become a key arbiter of content on the web. For example, a user logged into Facebook searching for news on Bing would see links to articles that a friend may have liked. People searching for generic terms, such as “cooking,” might see recipes their Facebook friends have annointed with a “like.” Where a person’s Facebook friends have not sounded off on a particular search term, they would see the most popular links from the collective Facebook community, redefining search altogether.”

Offline Gmail Google Calendar and Google Docs Planned

Google’s Sundar Pichai revealed that offline Gmail, Google Calendar and Google Docs are planned for this summer according to Techcrunch.

“All of this is a long time coming for Google. They’ve had options for going offline in the past with things like Gears, but it wasn’t perfect. And actually, Gears is no longer being supported by Google as Chrome gains many of the same features via HTML5.

Pichai also noted that there are already hundreds of apps in the Chrome Web Store with offline access. And that includes almost every game in the store. This, on top of the built-in 3G connectivity is all vital to ensure the vitality of Chromebooks”

Google to ‘Rent’ Chrome Laptops

Google tomorrow will announce sales of the new Chrome laptop in a $20 a month “student package” that combines both hardware and online services, writes Quentin Hardy on Frobes.

The product is almost certainly a precursor to an enterprise offering. Google Apps, an online product with features similar to Microsoft Office (word processing, spreadsheets, calendars, and other productivity software) is sold to business for $50 a year. An inexpensive Chrome laptop could be added to that for a small premium, somewhat the way mobile phones are sold below cost when tied to calling plans.

Having students try out the product — at a price cheaper than buying a laptop for school — amounts to a shakedown cruise for the eventual product. If successful, it also seeds the market for future demand, as students move into the workforce with expectations of working in cloud-based systems.

Microsoft to Buy Skype

Microsoft Corp and Skype Global S.à r.l today announced that they have entered into a definitive agreement under which Microsoft will acquire Skype, the leading Internet communications company, for $8.5 billion in cash from the investor group led by Silver Lake. The agreement has been approved by the boards of directors of both Microsoft and Skype.

The acquisition will increase the accessibility of real-time video and voice communications, bringing benefits to both consumers and enterprise users and generating significant new business and revenue opportunities. The combination will extend Skype’s world-class brand and the reach of its networked platform, while enhancing Microsoft’s existing portfolio of real-time communications products and services.

With 170 million connected users and over 207 billion minutes of voice and video conversations in 2010, Skype has been a pioneer in creating rich, meaningful connections among friends, families and business colleagues globally. Microsoft has a long-standing focus and investment in real-time communications across its various platforms, including Lync (which saw 30 percent revenue growth in Q3), Outlook, Messenger, Hotmail and Xbox LIVE.

Skype will support Microsoft devices like Xbox and Kinect, Windows Phone and a wide array of Windows devices, and Microsoft will connect Skype users with Lync, Outlook, Xbox Live and other communities. Microsoft will continue to invest in and support Skype clients on non-Microsoft platforms.

“Skype is a phenomenal service that is loved by millions of people around the world,” said Microsoft CEO Steve Ballmer. “Together we will create the future of real-time communications so people can easily stay connected to family, friends, clients and colleagues anywhere in the world.”

Skype will become a new business division within Microsoft, and Skype CEO Tony Bates will assume the title of president of the Microsoft Skype Division, reporting directly to Ballmer.

“Microsoft and Skype share the vision of bringing software innovation and products to our customers,” said Tony Bates. “Together, we will be able to accelerate Skype’s plans to extend our global community and introduce new ways for everyone to communicate and collaborate,” Bates said.

“Tony Bates has a great track record as a leader and will strengthen the Microsoft management team. I’m looking forward to Skype’s talented global workforce bringing its insights, ideas and experience to Microsoft,” Ballmer said.

Speaking on behalf of the investor group that sold Skype to Microsoft, Egon Durban, managing director of Silver Lake, said: “We are thrilled with Skype’s transformation during the period of our ownership and grateful for the extraordinary commitment of its management team and employees. We are excited about Skype’s long-term future with Microsoft, as it is poised to become one of the world’s most dynamic and comprehensive communications platforms.”

Founded in 2003, Skype was acquired by eBay in September 2005, and then acquired by an investment group led by Silver Lake in November 2009. Skype has made impressive progress over the past 18 months under Silver Lake’s leadership, increasing monthly calling minutes by 150 percent, developing new revenue streams and strategic partnerships, acquiring the intellectual property powering its peer-to-peer network, and recruiting an outstanding senior management team.

Other members of the selling investor group led by Silver Lake include eBay International AG, CPP Investment Board, Joltid Limited in partnership with Europlay Capital Advisors; and Andreessen Horowitz.

The acquisition is subject to regulatory approvals and other customary closing conditions. The parties hope to obtain all required regulatory clearances during the course of this calendar year.

File Hosting Sites Not Safe For Private Data

Academic researchers say they’ve uncovered weaknesses in dozens of the most popular file hosting sites that allow people to gain unauthorized access to data that’s supposed to be available only to those selected by the user, reports Dan Goodin writing on Theregister.

“The services, which include sites such RapidShare, FileFactory, and Easyshare, allow users to upload large files and make them available to anyone who knows the unique URI (or Uniform Resource Identifier) that’s bound to each one. Users may post the link on websites or forums available to the public or share it in a single email to prevent all but the recipient from downloading it. RapidShare, for instance, says it can be used to “share your data with your friends, colleagues or family.”

But according to academics in Belgium and France, a “significant percentage” of the 100 FHSs (or file hosting services) they studied made it trivial for outsiders to access the files simply by guessing the URLs that are bound to each uploaded file. What’s more, they presented evidence that such attacks, far from being theoretical, are already happening in the wild.”

Paywalls Vs Free News Site

Oliver Reichenstein. writing on Informationarchitects has posted a very interesting article “Business Class: Freemium for News?”

“I had a perspective changing talk on the subject of pay walls with the chief executive of a big publishing company (no, I can’t tell you who). He asked me what I think about pay walls. I told him what I always say: The main currency of news sites is attention and not dollars and that I believe that it is his job, as a publisher, to turn that attention into money to keep the attention machine running. He nodded and made the following, astonishing statement”:

:If you’ve been designing online newspapers as well, of course, you know that designers cannot solve this problem by themselves. Newspapers need to make money. And most newspapers look the way they look because the design briefings are the way they are. The following comparison demonstrates how much space and attention that marketing strategy needs to pay for the product, and how small the space is for actual content:

“I can’t see pay walls working out either. But we need to do something before we lose all of our current subscribers. Sure. It’s a tough business environment, but… But the flight industry is a tough environment too, and they found ways. So tell me: Why do people fly Business Class? In the end, an airplane brings me to the same place regardless of whether I fly Economy or Business Class and the massive price-increase I pay doesn’t compare the difference in value.”

“There is no information shortage online—if I can’t read this article, I’ll read another.

Pay walls weaken the main attractor (content) of your site and complicates the user experience (login on different platforms). Some leave social media back doors for pro users, but that’s not a good long term strategy either, as more and more people are using social media to find content.

Often pay walled news sites feature the same amount of marketing noise as free sites. Paying customers of course are more attractive clientele, but… Paying for news and then dealing with a silly blinking bonanza while reading doesn’t seem like a fair deal.”

POP3 Email Accounts in Gmail

PC World has published a useful walk through “Setting Up POP3 Email Accounts in Gmail” for those changing to cloud email service Gmail.

“When you make the switch from Microsoft Office to Google Docs, you don’t just lose Microsoft Word and Excel, you also lose Outlook.

So, for any readers who may wish to follow in my footsteps, or who stumble across this project at some point in the future, we are going to take a step back today and go over the steps to add a POP3 email account to Gmail. As a side note, I tried this in IE9, Firefox, and Chrome, and the buttons and text did not render properly in IE9. I recommend using Chrome for this process”
