Patent attributes
The subject invention relates to a system and method for video summarization, and more specifically to a system for segmenting and classifying data from a video in order to create a summary video that preserves and summarizes relevant content. In one embodiment, the system first extracts appearance, motion, and audio features from a video in order to create video segments corresponding to the extracted features. The video segments are then classified as dynamic or static depending on the appearance-based and motion-based features extracted from each video segment. The classified video segments are then grouped into clusters to eliminate redundant content. Select video segments from each cluster are selected as summary segments, and the summary segments are compiled to form a summary video. The parameters for any of the steps in the summarization of the video can be altered so that a user can adapt the system to any type of video, although the system is designed to summarize unstructured videos where the content is unknown. In another aspect, audio features can also be used to further summarize video with certain audio properties.
