Computer vision has proven to be much more difficult than early artificial intelligence pioneers thought. In 1967 Marvin Minsky assigned a graduate student to the problem of computer vision, believing that the problem could be largely solved within one summer. AI researchers are still grappling with the difficulties of computer vision, but substantial progress is being made. 20 years ago a 16,384 processor, 250 MIPs supercomputer was needed to provide even the most rudimentary vision. Today even inexpensive single-chip Digital Signal Processors (DSPs) can provide 4,800 MIPs, and such DSPs will soon cost only a couple of dollars. Moreover, digital cameras capable of displaying high-resolution images are themselves becoming dirt cheap. These developments will not only be a boon to robotics and AI, but will also allow computers to interact with computer users in new ways. Computers might soon be able to “read and react” based on an individual's expression. The problem with this approach is that people's facial expressions vary greatly. Some people, for instance, smile when they are angry or upset. A computer that misreads human expressions could be even more exasperating than a computer that misreads verbal commands. Until our computers achieve general intelligence, they may have a difficult time responding to all but the most exagerated human expressions.

If computers start to judge human emotions, let's hope it's not American emotions, twisted by paranoia/greed for other countries resorces. Liberating oil reserves from a dictator they installed & then installing another puppet,and killing many innocent people in the process!
What really makes me sick is you so called FREE people haven't got the BALLS to confront what IS wrong..THIS WAR!!

Michael Moore was born in Flint, MI and lives in Manhattan. Do your research!! His first film was all about his place of birth!!!
Besides, its better to see an asshole who isn't coy about his beliefs, like Moore, than someone who doesn't have the guts to put “all their cards on the table,” like the Susan Saradons and Tim Robbins of the world. Also, unlike all the other self-righteous hollywood celebrities, Moore is actually entertaining in his opinionated rants, unlike the high-school educated entertainment monkeys we call actors that get in one-sided public forums to express their liberal views, retreat from criticism and take themselves too seriously.
PS. Anyone adamantly opposing or supporting this war needs a history lesson or two. This is a messy, complex decision that requires much thought and I respect Bush for taking a chance to try to make a better tomorrow. - by Michael Moore fan

I'm sorry but posting your half witted, emotional (non factual), antiwar crap on a story about computer vison on geek.com is almost as stupid as your statements. What the hell are you trying to acomplish? If you are trying to weaken your argument, and lose any respect you might have had, good job. - by MacMurphy

This is so sad! I wish you would go and live on Fantasy Island you big pussy in dyre need of a reality check. If you are going to gripe at least go to some political site where someone may actually give a shit. I hope someone around you realizes what a jackass you are and actually gives you a good kick to the pants.

|CAN but Won't (6:25pm EST Mon Mar 24 2003)
Taking a CHEAP shot at Canada, simply because we opted not to be part of murdering 5 million people, is the kind of bully post I would expect from an American.
Do stop and think people.. You have Bush threatening for months to attack unless Saddam gives up the WMP's. But he NEVER EVER gives us proof that he says he has, of where these weapons are. Where are they? The inspectors NEVER found them!
Now. Want think about this some more before you way your righteous crap around again? F'g bullies. You make me sick. - by Swiss_THIS!

|Cheapest Optical Recognition – priceless? (7:36pm EST Mon Mar 24 2003)
I wonder how cheaply an “optical recognition” system could be built. For example, with 1 or 2 megapixel cameras snapping shots of a room of obstacles at once persecond. Download that information into a laptop PC running linux optimized on a 64-bit Hammer CPU. Then get freeware that can plot a course through the obstacles, based on the stereo-vision.
2 used megapixel cameras: $100
Hmm. For anything else, Hammer on a laptop might not be so cheap. - by FreezeBrothers

|Re: Swiss_THIS (10:37pm EST Mon Mar 24 2003)
First off, we don't need/want Canada's help. Going to war without Canada or France's help is like going deer hunting without an accordian.
Now, I know this will hurt, but try to use some intelligence here: Bush and his administration proved that Saddam has these weapons… did you miss Colin Powell's address to the UN??? It would be irresponsible and stupid to say their locations over the air and directly into Saddam's air-conditioned palace and 54 inch plasma TV. An hour later they'd be moved somewhere else, then we'd look like fools, and we could never find them once we go in. This is not a hard concept to grasp.
Secondly, Bush isn't going after Saddam because he has biological or nuclear capability, but because he's used them, and against his own people no less. Not another difficult concept is the fact that in war you sometimes have to blow shit up to win. Weapons such as these, in the hands of responsible leaders whom we can hold accountable for their actions, makes me feel much safer than letting some jackass over in Iraq have them.
The only way to beat a bully, such as Saddam, is to become a bully yourself.

|No weapons? (11:15pm EST Mon Mar 24 2003)
What about the chemical weapons that the captured Republican Guard soldiers said they have orders to use? What about the SCUD missles that Saddam said he didn't have? Oh… wait… he used those. What about the Geneva conventions…? Wait… hes not following them at all… parading executed soldiers around and mutilating their bodies…
The Iraqi regime has been lying… and we're finding out what they're doing now. Just watch tv. Just be glad Bush did something before Saddam did. - by The Truth

|Found weapons??? (12:20am EST Tue Mar 25 2003)
Where are these weapons they found? Donald Rumsfeld appeared on CNN this morning stating that iraq has YET to use any of these weapons, nor have any been found so far. This is a war filled with propoganda on both sides. Bush says he wants to “free the Iraqi people”, ya so they can be more like americans? Saddam was on his way out anyway, Most middle eastern countries want him out, in a few months he would have most likely been forced to step down, along with his regeme. I agree with Noob Saibot when he says that somtimes you need a bully to take care of a bully, but not in this case. Bush really jumped the gun on this war, I think he gets the itchy trigger finger from his dad. Lets face it, war is good for the us economy, and bush knows this. This is not really a war about the feedom of the iraqi people. - by gilligan
