Are there photo search engines online yet?
What I mean is this: to do a normal google search, we type in a word or a few words and off it goes.
is there a way to grab a photo, say of George W. Bush, and then ask a search engine to find all the same photos on the web, exact same photo?
I would call this a photo search. Has anyone invented this kind of technology yet? are they working on it? is it a doable idea?
For example, say you have a photo of a long lost friend. you input the photo itself, and if that photo also exists somewhere on the Web, the search engine will take you there. YES? NO?
