Facial Recognition of Avatars
I suppose this sort of thing might be useful someday.
In Second Life, avatars are easily identified by their username, meaning police can just ask San Francisco-based Linden Labs, which runs the virtual world, to look up a particular user. But what happens when virtual worlds start running on peer-to-peer networks, leaving no central authority to appeal to? Then there would be no way of linking an avatar username to a human user.
Yampolskiy and colleagues have developed facial recognition techniques specifically tailored to avatars, since current algorithms only work on humans. “Not all avatars are human looking, and even with those that are humanoid there is a huge diversity of colour,” Yampolskiy says, so his software uses those colours to improve avatar recognition.
