Abstract
A “Video Browser” provides an intuitive user interface for indexing, and interactive visual browsing, of particular elements within a video recording. In general, the Video Browser operates by first generating a set of one or more mosaic images from the video recording. In one embodiment, these mosaics are further clustered using an adjustable similarity threshold. User selection of a particular video mosaic then initiates a playback of corresponding video frames. However, in contrast to conventional mosaicking schemes which simply play back the set of frames used to construct the mosaic, the Video Browser provides a playback of only those individual frames within which a particular point selected within the image mosaic was observed. Consequently, user selection of a point in one of the image mosaics serves to provide a targeted playback of only those frames of interest, rather than playing back the entire image sequence used to generate the mosaic.
