This Royal Wedding AI is a reverse image search for rich people

The application uses machine learning and, by extension, artificial intelligence, to properly identify people's faces and surface relevant factoids. Users can access Who's Who either through Sky News's mobile app or its website. The idea is to provide digital onlookers second-screen content to fill in gaps during the event. The app will, in real time, identify the faces of people at the wedding. According to a press release, the app uses Amazon Rekognition tools to name people in the crowd and then surface biographical information about them. As Sky News explains it, Who's Who will "[name] wedding guests as they arrive for the ceremony and tells people about their connection to the royal couple."
