The Informedia Digital Video Library project, initiated in 1994, uniquely utilizes integrated speech and image and natural language understanding to process broadcast video. The project's goal is to allow search and retrieval in the video medium, similar to what is available today for text only. To enable this access to video, fast, high-accuracy automatic transcriptions of broadcast news stories are generated through Carnegie Mellon's Sphinx speech recognition system and closed captions are incorporated where available. Image processing determines scene boundaries, recognizes faces, and allows for image similarity comparisons.
