Annotation and Segmentation for Multimedia Indexing and Retrieval.


In this paper we describe a method for indexing and retrieval of multimedia data based on annotation and segmentation. Our goal is the retrieval of segments of audio and video suitable for inclusion in multimedia documents. Annotation refers to the association of text data with particular time locations of the media. Segmentation is the partitioning of continuous media into homogenous regions. Retrieval is performed over segments of the media using the annotations associated with the segments. We present two scenarios that describe how these techniques might be applied. In the first, we describe how excerpts from a video-taped usage study of a new device are located for inclusion in a report on the utility of the device. In the second, we show how sound bites from a recorded meeting are obtained for use in authoring a summary of the meeting.
