Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for learning a structure of a video in unmanaged setting to detect events within the video consistent with the structure of the video. <P>SOLUTION: Sets of features are selected. From the selected features, a hierarchical statistical model is updated, and an information gain of the hierarchical statistical model is evaluated. Next, redundant features are filtered out and the hierarchical statistical model is updated based on the filtered features. A Bayesian information criteria is applied to each model and the feature set pair, which can then be rank ordered according to the criteria to detect the events in the video. <P>COPYRIGHT: (C)2005,JPO&NCIPI
