Google plans to introduce a mobile application that would allow users to snap pictures of people's faces in order to access their personal information, a director for the project said this week.The article goes on to say that there is no timeline for release, but Google's interest in the subject should be obvious.
Face recognition, like other biometric applications, is really just a very specific type of computerized object recognition. For now, Google's can only apply its algorithm to text-based queries. I'm sure Google is aware that it would be very useful if they could make sense of image, audio or other types of files as search terms. Face recognition is a logical starting point.
