When I was in the advertising business, one of the core products I created was a brandsafety product - basically preventing advertisers from advertising on dodgy sites. I messed around with algorithms that detected nudity (because big brand advertisers don't want their ads showing up on porn sites). One of the more interesting and simple-to-use one is actually a simple averaging of the images across multiple samples. That one was easy to implement and has relatively good results. In the end though, I ended up not using it because text clustering algorithms worked better in classifying content.
