Sectra virtual autopsy table available now, Stan Brakhage nonplussed
Though not offering the sort of stark, terrible beauty (or the gore) of The Act of Seeing with One's Own Eyes, Sectra's Visual Imaging Table will let you perform a "virtual autopsy," by using CT and MRI scans to place 3D recreations of a patient's body on a large, multitouch table. What's more, the body can then be examined -- and even cut with a "virtual knife." And it's finally available "to the masses," as one company rep put it in an email this morning (although we sort of figure that if you have an MRI machine you probably aren't one of "the masses"). Check out the PR after the break, or hit up the source link to get one for yourself.
UNC researchers develop a system for creating 3D models using images pulled from Flickr, off-the-shelf components
A group of researchers from the University of North Carolina and the Swiss university ETH-Zurich have teamed up to develop a system for creating 3D models of famous landmarks using photos from photo sharing websites like Flickr. Unlike previous projects at Microsoft and the University of Washington, the team at UNC used a home PC (albeit one with four GPUs) to process millions of images pulled from the Internet and construct 3D models of such landmarks as the Colosseum and the Roman baths at Sagalassos (above). And all the models were created in less than a day. According to UNC Chapel Hill's Jan-Michael Frahm, the process improves on current commercial systems by a factor of 1,000 to one. "Our technique would be the equivalent of processing a stack of photos as high as the 828-meter Dubai Towers, using a single PC, versus the next best technique, which is the equivalent of processing a stack of photos 42 meters tall – as high as the ceiling of Notre Dame – using 62 PCs," he said. "This efficiency is essential if one is to fully utilize the billions of user-provided images continuously being uploaded to the Internet." He sees any number of uses for this technology, from AR integration to 3D maps for rescuers in case of a natural disaster.
Gurus track inhaled nanoparticles as they experience Mach 5 lung travel
Ever wondered what kind of objects you inhale on a daily basis, leaving your lungs to sort out whatever it is that you snort in? Scientists at the Beth Israel Deaconess Medical Center and the Harvard School of Public Health have, and they're tired of simply imagining. A crew of wizards at the institution have started to test a so-called FLARE system (fluorescence-assisted resection and exploration), which enables them to see and monitor nanoparticles as they enter and travel through the lungs. The goal here is to "determine the characteristics and parameters of inhaled nanoparticles that mediate their uptake into the body -- from the external environment, across the alveolar lung surface and into the lymphatic system and blood stream and eventually to other organs." In short, this here study may offer a better understanding of the health effects surrounding air pollution... or restart the mask-wearing craze that SARS initiated. But probably both.
Artificial bee eye gives diminutive robotic air drones wider range of vision
We'd bother telling you up front that it also gives them a new sense of purpose, but you're already versed in how the impending Robot Apocalypse is going to go down. Wolfgang Stürzl and his best buds over at Bielefeld University in Germany have just published a report detailing how an artificial bee eye could improve the vision of miniature robots -- ones that fly, in particular. By using a catadioptric imaging system, which captures an image using both mirrors and lenses, they were able to utilize a single camera to capture a full 280-degrees of vision, and a lowly internal computer is able to stitch the two panes together in order to create a usable image that humans can interpret. The idea here is to provide more sight with less space, bringing us one step closer to actually having our very own 'fly-on-the-wall' moment. Comforting, no?
Planck telescope maps the universe in search of primordial light
Yep, that innocuous-looking picture above is the whole freaking universe, as perceived by the Planck telescope -- a long-wave light detector that's been catapulted into space to search for Big Bang clues. The European Space Agency is using it in order to get the most precise information to date on Cosmic Microwave Background radiation (apparent in the image as the magenta and yellow mush in the, ahem, background), which could in turn enlighten us on the conditions that gave rise to all of us omnivores prowling a gravity-assisted, ozone-protected, floating rock. The first mapping run took just over six months to complete, but the plan is to produce four such images using the Planck's super-cold (nearly at absolute zero) sensors before retiring the thing. Results are expected no sooner than 2013, so please do slide back from the edge of your seat.
Hyperspectral imaging reveals Declaration of Independence rough draft dubbed citizens 'subjects'
Imagine, if you will, Thomas Jefferson sitting down to pen (or quill) a rough draft of the Declaration of Independence early in 1776... you know, when the colonies that would become the United States of America formally explained their decision to become independent states, and thus not be a part of Great Britain any longer. Imagine him writing the words "our fellow citizens" -- but know that, thanks to hyperspectral imaging, the Library of Congress has confirmed that he originally wrote "our fellow subjects" -- but then scrubbed it out and replaced it with the word "citizens." Personally, we feel pretty happy with the knowledge that the founding fathers chose their words so carefully -- after all, "we hold this stuff to be super obvious 'cause all dudes are like, basically the same" just doesn't have the same ring to it, now does it? Hit up the Boing Boing source link for far more photos.
Russell Kirsch helped create square pixels, now he wants to kill them off
Did you know that we're only 53 years removed from the very first digital image? I know, with everyone on your street having a good 2GB of Facebook-uploaded, privacy-be-damned photos, it all seems so pedestrian, so typical. But back in the monochromatic 1950s, when Marlon Brando and Elvis were still young whippersnappers and the UK was busy crowning a new Queen, Russell Kirsch became the first man to create a digital picture, by scanning in a photo of his baby son. Now, half a century wiser, Russell is back to apologize for introducing that cursed square pixel into our lives, and to try to remedy all the jagged little edges we've been seeing on our screens ever since. According to old Rus, squares were just the logical solution at the time, but now that we can splash bits and bytes around with reckless abandon, he's come up with a new algorithm to smooth images beyond what's possible with simple squares. His new idea inserts 6 x 6 masks where there once was just one pixel, with adaptive calculations making for a more realistic representation of the underlying optical data. The sample above shows what improvements this new technique can deliver, with Russell's son doing the posing once more -- you'll find his decidedly younger visage in the 176 x 176 proto-pic after the break.
OmniVision brings RAW shooting to mobiles with new 5 megapixel sensor
It seems that the megapixel race in the mobile arena has slowed (temporarily, at least), but it's not like innovation has completely ground to a halt. OmniVision, which made waves around a month ago with its 14.6 megapixel CMOS sensor, has just announced what may be the most significant introduction in the cameraphone space... ever. The 1/4-inch, 5 megapixel RAW sensor is said to offer up best-in-class low light sensitivity (680-mV/lux-sec), and it can also capture 720p video at 60 frames per second or 1080p at 30 frames per second. The real kicker, however, is its ability to shoot in RAW, which would give cameraphone shooters a much greater range of editing options when it came time to tweak before hitting Flickr. We're told that the chip is sampling now and should hit mass production this July, and we'd be lying if we said we weren't falling over ourselves to get ahold of a RAW-capable smartphone.
Fujifilm intros 3D Print System, which probably requires wicked expensive ink
What do you do if you concoct one of the world's first 3D point-and-shoot cameras? Why, you concoct a 3D printer (definitely not pictured) to work with it, of course! Fujifilm has just kicked out its new 3D Print System, which enables 3D photographs to be created "on the spot" using dye-sublimation technology to print directly on to the base of a lenticular sheet. Unfortunately, prints will only be available in four sizes ranging from 4- x 6-inches to 6- x 9-inches, but we're hoping that some sort of magical firmware update will enable poster-sized prints for those really looking to drive their retinas batty. Mum's the word on a price, but it should hit UK shelves by April for an undisclosed rate.
3D camera breaks world record with 158 lenses
Sure, there are viable commercial options for taking photos in three dimensions, but if you really want to capture 3D images (and you happen to be attached to a major university) you can always go the route of Associate Professor Ishino Youzirou and company. The camera that they developed at the Nagoya Institute of Technology sports 158 lenses arranged on an 18.5-inch aluminum arc frame. The school's combustion engineers will use it to study irregular flames -- all the while content in the knowledge that they've entered the Guinness Book of World Records for building the camera with the most lenses. This is certainly safer than Youzirou's other attempt to enter the Guinness book, Most Live Rattlesnakes Held in the Mouth (the record for that, by the way, is ten).
TI's OMAP-DM5x coprocessors promise 20MP cameraphones, 720p recording and freedom from heartache
Another season, another Texas Instruments coprocessor for us to wonder about. For what feels like ages now, TI has been pumping out silicon that promises to bring high-def recording capabilities to cellphones, but by and large, most everything has been stuck at VGA or below. Oh sure, we've seen our first batch of 12 megapixel cameraphones, but it's not like those things are replacing DSLRs en masse. Bitterness aside, the OMAP-DM525 coprocessor is supposedly capable of bringing 20 megapixel imaging to handsets along with 720p video recording, while the OMAP-DM515 hits the ceiling at 12 megapixels. Of course, the DM525 won't actually be ready for volume production until sometime next year, but here's hoping a sample or two slips out at CES.[Via LetsGoDigital]
Samsung's 'Tap and Take' teaser hints at revolutionary, unicorn-approved Smart Cameras
Samsung sure has been milking this whole "teaser" thing for all it's worth of late, with the newest mystery coming to us in the form of its fresh 'Tap and Take' campaign. From now until August 12th, users can give the read link a visit in order to ingest clues about the outfit's upcoming line of Smart Cameras. These wildly intelligent shooters will purportedly "transform the way consumers take pictures," and they just might provide each and every American with free health care, solve world hunger and put the mighty Hubble to shame. The whole thing will be revealed in full on August 13th, but for now, why not drop a comment below as to what you think will be so revolutionary about the forthcoming point-and-shoot range?[Via Korea Newswire]
Friday Favorite: Photomatix Pro
There are few times I have used software that really caused my jaw to drop. Photomatix Pro did just that. It's a Mac OS X utility that allows you to create what are called High Dynamic Range (HDR) images from separate digital exposures taken at different shutter speeds (exposure levels). These pictures are far more colorful and impressive in their tonal range and saturation.Many digital cameras have something called AEB, or Automatic Exposure Bracketing. You click the shutter once, and the camera takes 3 pictures instead of just one. In my case I usually shoot a normally exposed image, then one 2 stops under, and another one 2 stops over. If your camera doesn't have AEB you can do this manually.Photomatix Pro combines the three exposures you've taken into one, and tone maps the image into a JPEG or TIFF that displays a really wide dynamic range. The result is often a stunning picture, with little loss in the shadowy areas, and no blown-out highlights. It's hard to do if you are shooting people because they will move between the 3 exposures, but works great with landscapes. A tripod is recommended, but I've done just fine handheld and Photomatix Pro will automatically line up (register) the 3 images.Words can't describe the difference, so I've included a few examples to look at. There are other Mac apps that do similar things, but I've had the best luck with Photomatix Pro. They also make a Photoshop plug-in and one for Aperture, but I think the full program is the best. Newer versions of Photoshop also support the creation of these HDR images, but the results are not as spectacular in my view. There is also a free, basic version of the program that lets you combine 2 images, but it is simply not as effective.You can search for a lot of information on HDR photography on the web. I have found this site to be very good, and it reviews the different software that is available. It's very easy to overdo the look of HDR images, and Photomatix Pro gives you lots of control. You can make your images really good, or outlandish. The control is in the hands of the photographer. To many, HDR will be old hat, but a lot of photographers haven't tried it, and will be pleasantly shocked at the results. Since you can download Photomatix Pro for free, if you are serious about digital imaging, I'd give it a tryout. If you buy the full version it is US$99.00.Here are some examples of how HDR imaging works. Of course these images are reduced in quality and resolution, so they only hint at the differences.%Gallery-65254%
Acoustic superlens could mask ships from sonar... in theory, anyway
Man, the mad scientists are really on a roll of late. First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.[Via Slashdot]
USB ultrasound device coming to a Windows Mobile phone near you?
Two computer science professors at Washington University in St. Louis have produced a USB ultrasound probe which is compatible with Windows Mobile smartphones. The project, funded by Microsoft, has developed and optimized probe that uses less power, and is enhanced for data transfer rates on cellphones. The devices could be especially useful in on-the-go situations -- for ambulances, emergencies, and for use by traveling medical staff. The makers also foresee that the device could positively effect medical practice in the developing world, where equipment and doctors can be scarce, and a small, but cellphone access is ever increasingly prevalent. We don't know when these might be commercially available, but they are hoping to sell them for around $500 -- significantly cheaper than many portable ultrasounds, which can cost almost $30,000. Update: Check out another image after the break.[Via Physorg]
Scallop Imaging wide-angle security cams look to the sea for inspiration
We're not too sure what's up with New England-based institutions and inspiration from the depths, but the two seem to have some kind of intrinsic connection. The latest company to prove such a wacky assertion true is Boston's own Scallop Imaging, a Tenebraex subsidiary that has developed a "low-cost" security camera that sees 180 degrees of view without fisheye distortion or the lag present in pan-and-tilt alternatives. Additionally, the multi-eyed cam automatically stitches and downsamples images, and can capture a new 7-megapixel still to transmit over Ethernet "every second or two." It's small enough to be placed into a light socket-sized hole, and it's powered by the same Ethernet cable that links it into a building's surveillance system. Of course, the fun won't stop there, as the outfit is already looking at automotive applications of the Digital Window, including "distortion-free backup cameras for the rear ends" of vehicles.
Scientists copy keys with computer imaging to make sure we feel insecure
Not satisfied with the time-honored traditions of lockpicking or bump keying, computer science professor Stefan Savage and a handful of grad students at the University of California at San Diego have developed a computer system that makes a functional copy of a key based solely on a photograph, regardless of angle or distance -- the image resolution just has to be high enough to make out the details. They claim they did this "to show people that their keys are not inherently secret" so they'll be more careful about flaunting them around in their Flickr photos, but we're worldly enough to know that they really did it to steal beer from rival frat houses. Shame![Via Switched]
MIT conjuring up 6D "super-realistic" image system
2008 has been somewhat of a banner year for 3D, but the brilliant minds at MIT are already working up a system that'll put U23D to shame. Hailed as a "super-realistic image system," the invention produces "6D" images that not only have a full three-dimensional appearance, but also "respond to their environment, producing natural shadows and highlights depending on the direction and intensity of the illumination around them." Without relying on electronics or active control, the process could be used to produce images with an "unprecedented degree of realism" -- resulting in something associate professor Ramesh Raskar calls the "ultimate synthetic display." As expected, initial applications for the ultra-pricey ($30 per pixel, currently) system revolve around digital signage / advertising, but it's really just a matter of time before Six Dimensions of The Jonas Brothers hits a cinema near you. Save us.
Hydra 1.5: HDR and OS X beauty revisited
Back in January, the folks from Creaceed released version 1.0 of Hydra -- a Leopard-only, GPU-powered photo application for creating High Dynamic Range photos that competes with the much-renowned Photomatix Pro. Just in time for the Apple Design Awards version 1.5 of Hydra is available. With more tone-mapping options, an image-navigation HUD, RAW importing (should you wish not to convert to 16-bit TIFF before importing), a plethora of Aperture options (more on those in a moment), and many more new features it's certainly a compelling release.As mentioned before, there's plenty of Aperture integration with this release. As well as being able to import photos from (and export photos to) Aperture, Hydra is now available as an Aperture plugin (beta) - based on the all-new Aperture 2.1 Plugin SDK - that allows you to create HDR photos from within Aperture.Unlike the cross-platform Photomatix Pro, Hydra's UI is the epitome of OS X slickness -- replicating much of the look and feel of both Aperture and other iLife applications. We'll be taking a look at both Hydra and Photomatix Pro in the near future to see whether Hydra's charms are merely skin deep.Hydra 1.5 costs $59.95, and is a free update for those we already have a license.
Picturesque 2.0 released
If you think back to June last year, Picturesque - a neat lightweight image editor - was the deserving recipient of an Apple Design Award for 'Best Student Product'. So it's fitting then that, just in time for this year's Apple Design Awards, Acqualia Software has released version 2.0 of Picturesque. So what's new? First of all, it's a Leopard-only application with a Core Animation-powered graphics engine. Throw in an entirely new all-in-one window interface, plenty of fancy new effects (such as the 3D iChat effect), a Media browser for easy iPhoto access and AppleScriptability (Picturesque meet Cory) and it all adds up to a rather tasty upgrade. With the release of version 2.0, a license for Picturesque will now set you back $34.95 whilst owners of version 1.0 can upgrade to the latest version for just $12.95.
