Alan, That's nonsense. A camera, or a person, can look at a black and white scene, light-on or light-off. A person will still recognize the image. How? You can't tell. You can only write a monstruous program that will do nothing but what you teach it to do. And you can't improve on that. Your robots are clumsy, and you can't improve on that. Your chess-playing machine can't play checkers, and can't even learn how. You need a human to improve on that. You can't do OO-analysis, you need a human to do that. Your semantic web ... where is it? You can't integrate systems, you need a human to do that. This is an AGI blog, and writing program is not AGI, it is using human slaves to row.

Do you have ANY idea how cameras work? For every pixel, for every scan interval, the sensor will be affected by tens of thousands to millions of photons... What you get is a number. Typically, in most applications between 0 and 255. We can abstract that to some floating point value between 0 and 1 where 0 is almost no light and 1 is sensor saturation. You are given a matrix of these, We will assume perfect pixels that are vertically aligned and there are no sensor artifacts. Your AI must find and encode the simplest possible theory of what objects must exist out in the world to have excited the sensors on your camera in such a way. That is visual perception. I'm getting sick and tired of reading this ignorant crap out of you. I expect it from the list clown but you should be smarter than this, that's why I'm so disappointed in you. =( -- E T F N H E D E D Powers are not rights. ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/18883996-f0d58d57 Modify Your Subscription: https://www.listbox.com/member/?&; d2 Powered by Listbox: http://www.listbox.com ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-c97d2393 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-2484a968 Powered by Listbox: http://www.listbox.com
