US Patent 7773813 Capture-intention detection for video content analysis

Systems and methods are described for detecting capture-intention in order to analyze video content. In one implementation, a system decomposes video structure into sub-shots, extracts intention-oriented features from the sub-shots, delineates intention units via the extracted features, and classifies the intention units into intention categories via the extracted features. A video library can be organized via the categorized intention units.
