I have come to think of any Dvorak story posted by Slashdot as meta-flamebait. They know it is just going to cause the comments to degenerate into a total circus of hatred.
Seriously though, I just don't believe it. I've worked on a number of DARPA robot projects, and have heard a lot of their babble. They claim to be funding all these fantastic ideas, but none of them ever work except in a limited capacity. The robot projects I worked on were very lame in that DARPA created these really specific environments for the robots that were light years away from what they were saying they were really going to do. All of the Universities involved failed to accomplish even the simplest tasks. So my experiance with them is that they talk a big talk, and no one ever goes back to check "hey did you really ever do that ?" Now granted, some of their work is supposed to be high risk, but they never emphasize which projects are expected to have a high failure rate. Largely because they don't care. It's really all about funding your academic buddies or whoever is going to be able to scratch you back in some way. It is very much an old boys network, with an emphasise on PR and not much about real science. Much like the MIT media lab. (Just thought I'd get another jab in there....)
Your definition of an edge is not mathematical. It is just in English.
So my proposed image is an unacceptable one ? Can you define the set of acceptable images mathematically, not just with language. What is "noise" ? Why is this discrete example the same as looking at the characteristic functions of the rationals ? That is an infinite dense set in the reals. Here everything is finite.
Forget discussing credentials. It is irrelevant here. I could say I have a Nobel prize.
I disagree completely with you about those edge detectors. If they are mathematically rigourous then there is a well defined answer that you should be able to give me for every input. Now consider the following input image: a bw matrix in a checkerboard pattern. What are the "edges" there ? What does Canny do ?
Give me a mathematical definition of an edge rather than pointing to someones (hack) algorithm.
You're proving my point. People in CV don't know what rigor is. But people in computer vision do have math envy and try to make stuff appear mathematical (such as that eigenfaces stuff).
After working in computer vision for 5 years I've realized that most problems aren't hard - they are not well defined. Mathematically face recognition is not a problem that can be stated.
Many other problems in CV are like this - edge detection, segmentation, etc. But people write hacks that work in restricted conditions and say they've solved.
And look, you could always just put on those Groucho Marx glasses.
This is an old urban legend. And the burden is on you to produce proof, not me, since substance abuse clinics all over the world treat it as a physical addiction.
Do you also think you can get a cold by going out in cold weather ?

I learned a lot from it about novas.
Protective eyeware. Believe me, from personal experience.
I seem to recall that the NeXT machines that I used in the 90's could do stuff like this with some piece of software. Anyone recall the name ?

That was ARPA, not DARPA. And I have little doubt that the culture of ARPA in the 60's is different then the culture of DARPA now.

to understand DARPAese. (Try reading some of their PPT slides.)
Argghhh! Yes, OK if there are more people who are Republicans, then the Republicans win and vice versa.
Assuming a uniform probability distribution on parties, they will cancel each other out.
Yes the liver contains a lethal dose of Vitamin E. And the meat always contains trichonosis, so make sure it is well cooked.
And can we please stay on topic about the upcoming evil polar bear invasion ?
Hey that explains why congressional pages live so long!
they had a system like this.

Penny Smith's supposed solution to the Millenium problem (Navier Stokes) turned out to be wrong.
Actually the best predictor is how many Herman Miller chairs your office has.
BTW, were these things designed to be sand proof ?
My only gripe is the binding. The whole thing fell apart in about a month of normal use.
Right. People don't use it because no one can get it to work well enough. My cell phone has it and I don't bother.
This article is somewhat out there. How can an operating system with such market share be irrrelevant ?
No not flamebait, just a more different view of things.
If you've got nothing to hide, then what is the big deal ?
Yeah, that Al Gore thing was outrageous - Yau says HE invented the internet.
