Specialized image recognition especially detecting objects with fairly rigid structures or common color patterns seems like a nice intermediary step relative to the more complex issue of detecting arbitrary objects. During a few drunken nights my friends and I have had many conversations about doing an image crawler that would detect nipples. You know that bathing suit that's see through that your friend's hot girlfriend likes to wear and posted a photo of herself on MySpace (just to be a tease)? Yeah, we wanted to find those photos. We were going to call the site tittr.com. Turns out nipple detection has many practical applications especially in digital mammography and there's even been a few research papers written on the subject.
