Search Engines for Multimedia: Images, Audio and Video Files

As more digital multimedia archives are developed, they require specialized search engines can index and search these formats. Video and audio are hard to browse, so search engines can save significant time and effort in locating useful content.

Indexing multimedia is much more complex than indexing text. In some cases the media can be converted to text: broadcast television often includes digital text as closed-captions for the hearing impaired, and scene titles and captions within a video can be converted to text using OCR. Speech-recognition technology can digitize words spoken on audio tracks. Continuous media, such as video, also can be broken up into chunks by transitional effects, for better precision in results. Some groups are also working on form and shape recognition, which could allow searchers to draw a shape, such as a bridge or a tumor; or select an example picture and find others like it.
