Algebraic Video Thesis Abstract
Algebraic video integrates fundamental access methods for
digital video: composition, search, navigation and playback. Video
presentations are composed using a video algebra that
consists of a set of basic operations on video segments to produce a
desired video stream. The video algebra contains operations for
temporally and spatially combining video segments as well as for
attaching attributes to these segments. Algebraic video access
methods also include query and navigation operations. Query and
navigation allow users to discover video presentations of interest by
describing desired attributes and exploring a presentation's context.
Unlike previous approaches, algebraic video permits video expressions
to be nested in arbitrarily deep hierarchies. It also permits video
segments to inherit attributes by context. Experience with a
prototype algebraic video system suggests that algebraic video offers
a complete, integrated framework to access and manage video, is easy
to use, and that satisfactory performance is obtainable. The
prototype system is used to discover video segments of interest from
existing collections and create new video presentations with algebraic
combinations of these segments.
