Abstract
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.

17. A system, comprising:
-
a shot detector to determine temporal segments of video shots in video data;
a sub-shot detector to determine temporal segments of sub-shots in the video shots;
a feature analyzer to determine both attention-specific characteristics and content-generic characteristics for each of multiple features of each sub-shot, wherein the attention characteristic indicates a person'"'"'s attention degree on the scene or object to be captured or having been captured;
an intention unit segmenter to delineate intention units composed of the sub-shots according to the attention characteristics of the features of the sub-shots; and
an intention classifier to assign each intention unit to an intention category, such that the video data is capable of being organized by intention units. - View Dependent Claims (18, 19)
