Application No. 08/970,889
Independent claim 1 present in the application is
representative of Appellants' claimed invention and is reproduced
as follows:
1. A method for comprehensively representing video information
in a manner facilitating indexing of the video information,
comprising the step of:
segmenting a video stream into a plurality of scenes, each
of said scenes comprising at least one video frame;
dividing, using intra-scene motion analysis, at least one of
said plurality of scenes into at least one scene foreground layer
and a scene background layer;
representing each scene background layer as a mosaic, said
background layer mosaic defining a key frame of a respective
scene; and
representing each of said at least one video frames forming
said scene as a difference between initial video frame imagery
and a respective portion of said key frame.
