Abstract :
Algebraic video uses a set of basic operations on video segments to create a desired video stream. The video algebra consists of operations for temporally and spatially combining video segments, and for attaching attributes to these segments. Video streams of interest can be discovered with video queries that describe desired attributes. 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 can be used to create new video presentations from existing video libraries with query based discovery and algebraic combination of video segments of interest
