摘要
The invention provides a method for detecting usual and unusual events in a video. The events are detected by first constructing an aggregate affinity matrix from features of associated items extracted from the video. The affinity matrix is decomposed into eigenvectors, and the eigenvectors are used to reconstruct approximate estimates of the aggregate affinity matrix. Each matrix is clustered and scored, and the clustering that yields the highest scores is used to detect events.
