Interesting article. Read it before you comment. 
Tea Partiers say you don't understand them because you don't understand American history. That's probably true, but not in the way they want you to think. Late in 2012, I came out of the Lincoln mo...

We have what we think are breakthrough results in reconstructing natural looking mosaics from a hand-held event camera (DVS) and no additional sensing.

An event camera is a silicon retina which has no global shutter. Instead, each pixel is an independent and asynchronous brightness sensor which reports an event or spike whenever it measures a threshold change in log intensity along with the microsecond-precise timing of that change.

Our approach to recovering intensity mosaics from this output is an essential SLAM one of interleaved probabilistic filters to track the pure rotation pose of the camera (incrementally, event by event) while reconstructing a gradient map of the scene --- since each event, given an estimate of camera position and velocity relative to the estimated mosaic, improves our estimate of the component of the gradient in the mosaic in the instantaneous direction of motion. The gradient map can then be upgraded to an intensity map using Poisson reconstruction. We think that essentially the same method should extend to 3D depth map estimation and visual odometry in the near future, or other sorts of motion assumption up to generic optical flow estimation.

We can reconstruct mosaics with both higher resolution than the input event stream and huge dynamic range (the video shows log intensity mosaics and gradient maps), and we should be able to track extremely rapid motion against these. We think this really proves that the DVS device is doing what it is supposed to and capturing the really important information in a moving scene --- the changes --- at a hugely reduced data rate compared to standard video, but in such a way that the whole scene can be reconstructed if needed.

This work was led by +Hanme Kim with help from +Ankur Handa (now in Cambridge) and collaboration with Sio-Hoi Ieng and Ryad Benosman from the Institut de Vision in Paris, and will be published at BMVC 2014. Here is the paper: http://www.doc.ic.ac.uk/~ajd/Publications/kim_etal_bmvc2014.pdf

Are you a REVIEWER TYPE PERSON?  Are you interested in MAKER stuff and DIY?  I'm in the midst of writing my second DIY book, this time focused entirely on musical instruments and noise toys (many electronic or electro-acoustic, both traditional and odd-as-hell).  If you are possibly interested in a review copy, hit me with contact info and a link to your venue (or Amazon, or whateves):  http://davideriknelson.com/contact.html

I took a moment today to be wistful for skills I chose not to learn… and found an old hero's amazing performance.

This is a great look at the history of attempts to implement a basic income and what happens when it is done. I really feel that this is the direction we need to go. Having to work for money has been a great concept, but I think it is going to break in significant ways going forward.

Story
Tagline
My goal is to be the the shadowy face circled in photos in future documentaries
Introduction
I try to help independents and freelancers survive without growing their companies, because growth is the fastest path to dismay, hubris, and all the other modes of failure. Entrepreneurship is a cognitive disability, one that disrupts risk-seeking behavior and self-assessment, and as a survivor of the Entrepreneurship Industrial Complex I try my best to help young earnest people escape its fell clutches.

Much of that has been work done at Vague Innovation, LLC. Over the last few years,I've also been a co-owner of Workantile, a coworking community in Ann Arbor, MI.

I also teach machines to think about the world. That may sound like an exaggeration, but really the problem is your—our—misunderstanding of what we mean by "thought". We can talk philosophy ’til the cows turn blue, though, without settling that little argument… and that's an object lesson in itself. At any rate, a lot of my work on these projects seems on the surface to involve genetic programming, and they "think" because we have to use basic science after the fact to be able to understand what the hell they have done to solve our problems.

Which if you think about it, is an awful lot like psychology and evolutionary biology....

I know a bit of weird technical stuff and have a little common sense regarding business stuff, and for some reason this inspires folks to ask me to come visit and listen to them tell stories about their work and their goals and "the future". Usually I tell them they are wrong in a number of ways they've never considered, but nonetheless that seems to please them.

I digitize books, even when Google thinks they've "done" them, and then republish them all for free. More than republish them, in fact.

I pontificate endlessly about the nature of work, the economy, and rickety cultural assumptions along those lines. Mainly this ends up being stuff about agile project management, cascades of disintermediation, a bunch of stuff about the tacit revival of anarchism, and what it would be like to kill and eat a corporation—without harming any of its employees, of course, because as we all know, that would be wrong.

If we meet, I'll ask you two or three questions. "Who are you?" and "What do you want?" and maybe a third that depends on your answers to those.

And I always play scissors the first two rounds of rock-paper-scissors.
