  • Indexing the Video Frontier Wired News, February 5, 1998 by Chris Oakes
    Describes the issues of indexing and searching video data, which is much harder than text. Algorithms must find meta patterns, such as scene changes, to break down the data into manageable parts -- and these are different in different genres of video, such as documentaries or sports. Products make good use of closed-captioned text, text within the video and analysis of audio tracks to create storyboards and previews. More subtle indexing will require image analysis and pattern recognition. Products also work with Microsoft's NetShow streaming audio and video products. Includes information about Excalibur, Virage and Magnifi.
