Scientists reconstruct speech through soundproof glass by watching a bag of potato chips

Scientists reconstruct speech through soundproof glass by watching a bag of potato chips | pixels and pictures | Scoop.it

Your bag of potato chips can hear what you're saying. Now, researchers from MIT are trying to figure out a way to make that bag of chips tell them everything that you said — and apparently they have a method that works. By pointing a video camera at the bag while audio is playing or someone is speaking, researchers can detect tiny vibrations in it that are caused by the sound. When later playing back that recording, MIT says that it has figured out a way to read those vibrations and translate them back into music, speech, or seemingly any other sound.

Philippe J DEWOST's insight:

Throw your bag of chips before engaging in a confidential conversation. And avoid any line of sight.

We put Instagram's Hyperlapse app to the test in Times Square

We put Instagram's Hyperlapse app to the test in Times Square | pixels and pictures | Scoop.it

Instagram has a new app out. It's called Hyperlapse and promises to help iPhone owners shoot smooth, professional-grade video clips. You can speed them up and make time-lapse footage, or chose a slower pace to see Instagram's special image stabilization algorithms in action. To keep things steady, Hyperlapse relies on your iPhone's gyroscope rather than searching for traditional scene references like angles and high contrast tracking points. Having to compute all that information would murder your battery, and turning to the hardware's existing sensors is a clever way of avoiding the hassle. Best of all, everything's done through an incredibly simple user interface. There are no accounts to set up or sign into. Not an Instagram user? It doesn't even matter.

Philippe J DEWOST's insight:

Wondering whether Instagram only got "inspired" by Microsoft Research's demos at Siggraph a few weeks ago, or if there are deeper "similarities" beyond Instagram releasing an iOS "flavor" of Hyperlapse... (see http://sco.lt/91e8vp)

You Will Never Trust Your Brain Again After Experiencing The Following Optical Illusions

You Will Never Trust Your Brain Again After Experiencing The Following Optical Illusions | pixels and pictures | Scoop.it

Our brains have developed incredible tactics and coping mechanisms to help us make sense of the complex world around us. But some parts of our highly adaptive minds aren't perfect and can be exposed through carefully crafted illusions. 

Philippe J DEWOST's insight:

Great mashup of some very familiar (yet still enjoyable) and other unexpected optical illusions that either fool our mind, or expand it (look at the BW pictures where we tend to recreate colors)

Image Sensors World: Apple Applies for HDR Imaging Patent, Looks for Highly Innovative Sensor Engineers

Image Sensors World: Apple Applies for HDR Imaging Patent, Looks for Highly Innovative Sensor Engineers | pixels and pictures | Scoop.it
Philippe J DEWOST's insight:

Apple applies for US2012/041398 patent titled "Image Sensor Having HDR Capture Capability" by Michael Frank.

"...there exist disadvantages to the process of generating a HDR image from multiple independently captured images. For example, changes may occur when images are captured successively such that a composite HDR image generated therefrom may not be completely aligned. This may generate motion artifacts in the composite HDR image. Further, the images may be affected by local motion in the image scene, e.g., trees swaying in the wind, people and faces shifting slightly, etc. Additionally, the time required for a HDR image to be processed may be delayed based on the images to be captured."

Imaging App Market Analyzed by 6Sight

Imaging App Market Analyzed by 6Sight | pixels and pictures | Scoop.it
The photo and video mobile app market is not only booming, it is also changing rapidly. A new study from 6Sight finds that of the 475 top-ranking photo and video apps, 46 percent are less than six months old; 20 percent have just been introduced in the last 90 days.

The study, Photo/Video App Market Analysis, describes the trends in downloads, sales, and grossing rankings for free and paid Android, iPhone, and iPad apps. It also analyzes how these various rankings vary for certain segments. The findings include:

·       Photo and Video apps priced at the minimum store level of $0.99 are more common among top ranking apps introduced in the last 180 days than among older apps

·       iPad and iPhone Photo and Video apps that offer in-app purchasing options receive lower user ratings than those without

·       within the rankings of Photo and Video apps downloaded on iPads, apps that are only available on iPads offer less often photo enhancement functions than those that are also available on iPhones

See Classic Artworks Come To Life In Spellbinding "Beauty" Video

Animator and filmmaker Rino Stefano Tagliafierro has always found the intensity of the emotions he encounters through classical paintings unmatched by other artforms. And when he sat down to craft his latest short film, Beauty, he sought to convey the emotional impact of that artwork on him to an audience who might not be otherwise moved.

"The idea of Beauty is born from the desire to (convey) the main emotions that every person encounters throughout his life path," says Tagliafierro. "Classical art has always attracted my most intense emotions, so I decided to (let it) represent them."

The resulting project, Beauty, is a tour through the human life cycle--from birth to death--that draws on those classical paintings to tell that story in an absorbing way. By adding subtle animation to the artworks he chose, Tagliafierro actively depicts the motion that's only ever implied in the original pieces. The result is a stunning, haunting series of moving images that makes the work feel alive in different--often surreal--ways.

Philippe J DEWOST's insight:

Interesting artistic angle and amazing result on most processed paintings. Definitely worth a look.

Microsoft’s awesome Hyperlapse tech finally makes first-person GoPro videos watchable

Microsoft’s awesome Hyperlapse tech finally makes first-person GoPro videos watchable | pixels and pictures | Scoop.it
At Siggraph 2014, Microsoft Research has unveiled Hyperlapse, an ingenious algorithm that will actually make you want to watch first-person GoPro footage. Hyperlapse scans through hours of video footage, reconstructs the physical path that you took in 3D, and then generates a super-smooth 10x-speed hyperlapse video that is immensely watchable (it's a lot like a video game, in fact). Really, watch the videos below - I guarantee they'll be the coolest thing you see today.
Philippe J DEWOST's insight:

The folks at @MSFTResearch have done a helluva job, Hyperlapse looks to me like "Photosynth, meet video"...

MIT's Halide programming language can dramatically speed imaging processing | pixels and pictures | Scoop.it

A new programming language for image-processing algorithms yields code that runs much faster, reports the Massachusetts Institute of Technology — and this could lead to much better in-camera performance in dedicated devices and smart phones.

Nokia will acquire developers, technologies and intellectual property for imaging from Scalado. Nokia plans to make Scalado's headquarters in Lund a key site for Nokia's imaging software for smartphones, in addition to Nokia's existing locations in Espoo and Tampere, Finland.
The transaction is subject to customary closing conditions and is expected to close during the third quarter of 2012.
