Resist the attempt to project your own knowledge into the circumstance. You will find the attempt futile.
By "visual scene", I assume you mean the original image impressed on your retina, expressed as an array of pixels. The problem you describe is to reconstruct this image given the highly filtered and compressed signals that make it through your visual perceptual system, like when an artist paints a scene from memory. Are you saying that this process requires a consciousness because it is otherwise not computable? If so, then I can describe a simple algorithm that proves you are wrong: try all combinations of pixels until you find one that looks the same. -- Matt Mahoney, [EMAIL PROTECTED] ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=114414975-3c8e69 Powered by Listbox: http://www.listbox.com
