Sequence retrieval by contents through spatio temporal indexing

Sequence retrieval by contents can be supported with effective user interaction by indexing frame sequences through a symbolic representation of their contents. A language for the symbolic representation of the contents of image sequences is presented. This language incorporates and extends concepts of temporal logic so as to deal in a uniform way with both temporal and spatial features of digital video sequences. A prototype system which relies on the above language and supports retrieval by contents of image sequences through visual interaction is also briefly described
