Like Shazam for the TV, VideoSurf allows you to hold smart phones up to the screen to find out just who that actor is. VideoSurf is video search engine that has created a better way for people to search, discover, and watch online videos. Using computer vision VideoSurf has taught computers to “see” inside videos to let users find and watch videos that they really want to see.
With the upcoming mobile app, all you need to do is point your phone at what you’re watching on TV, capture a few seconds on video and VideoSurf will identify the show, actors who appear in it and suggest other videos you might like.
