Imaging an Image in the Mind

Via Slashdot and BoingBoing, researchers in Osaka, Japan claim a method of detecting images directly from a person's mind, published today in the the journal Neuron.:

Perceptual experience consists of an enormous number of possible states. Previous fMRI studies have predicted a perceptual state by classifying brain activity into prespecified categories. Constraint-free visual image reconstruction is more challenging, as it is impractical to specify brain activity for all possible images. In this study, we reconstructed visual images by combining local image bases of multiple scales, whose contrasts were independently decoded from fMRI activity by automatically selecting relevant voxels and exploiting their correlated patterns.

Binary-contrast, 10 x 10-patch images (2^100 possible states) were accurately reconstructed without any image prior on a single trial or volume basis by measuring brain activity only for several hundred random images. Reconstruction was also used to identify the presented image among millions of candidates. The results suggest that our approach provides an effective means to read out complex perceptual states from brain activity while discovering information representation in multivoxel patterns.

Variations on a Theme

My favorite Andre the Giant variation is still the "Andy van Dam has a posse" design that made it onto Onyxes at SIGGRAPH '94-- wish I'd taken pictures. It's been thrilling to watch Shepard Fairey's "Hope" poster become the iconic print image of this campaign, with "Hope" variations/sendups/ripoffs/etc. flowing from artists everywhere since it popped in January. The sweet story came full circle today when Fairey posted how excited he was to see Mad Magazine render Alfred E. Neuman in a "HOPELESS" homage. Rene Wanner assembled 84 variations, the bulk of them rude rather than clever, all linked to more info. My favorites (after Alfred E. Neuman) are Winnie and Luke. (via boingboing)

FinePix Real 3D System?!

No product yet, but Fujifilm has announced development of the FinePix Real 3D System, to include the new "Fujifilm Super CCD EXR" sensor, " not related to OpenEXR, but we can dream...
PHOTOKINA 2008, COLOGNE, GERMANY, September 23, 2008 FUJIFILM Corporation today announces a radical departure from current imaging systems with the development of a completely new, real image system (3D digital camera, 3D digital photo frame, 3D print) that marks a complete break from previous attempts to introduce this technology.

35mm Lens Adapters for HD

Just heard about a fascinating type of lens adapter for shooting through 35mm prime/zoom lenses on HD cameras-- project the image through the 35mm lens onto (moving!) ground glass, then shoot the resulting image with the HD camera through its optics dialed to macro. It's an "analog hole" approach that BW says works great. Manufacturers:

Stumbled onto Jaimie Warren photography and... digging it.

I'm sick of the disposability of things. There's the waste problem, the keeping-up-with-the-Joneses problem, and the fact that stuff is going to break down.

Why must every previous device be made obsolete with every new development? Why can't we value machines over lifetimes-- multiple generations-- as opposed to a few years or until the next one comes out?

I want to see a "chassis" approach to electronics-- replacing or repairing only components or subsystems to get new functionality.

The iPod Deb gave me is a good example of this-- worthless to her, a solid chassis with a bum battery and probably hard drive too. With a 8 or 16GB CF chip, a new battery, and bluetooth, it could keep going for decades.

Jim Woodring invented the Looty to look into his own eyes. Nachimir threw together an Instructable on it-- must try this out ASAP...
