Abstract:
A method of interpreting a digital video signal, wherein said digital video signal has contextual data, said method comprising the steps of:segmenting said digital video signal into one or more video segments, each segment having one or more video frames, and each said video frame having a corresponding portion of said contextual data; determining a plurality of regions for a video frame of a respective video segment; processing said regions for each video segment to provide a region adjacency graph at one or more temporal instances in the respective video segment, said region adjacency graph representing adjacencies between regions for a corresponding frame of said respective video segment; and analyzing said region adjacency graphs to produce a corresponding labeled region adjacency graph comprising at least one semantic label, said analysis being dependent upon a corresponding portion of said contextual data, wherein said labeled region adjacency graph represents an interpretation of said digital video signal.
