Generic approach to highlights extraction from a sport video
Alan Hanjalić · 2004
In this paper, we propose in this paper a method for extracting highlights from a sport TV broadcast. Unlike the existing highlights-extracting approaches our method does not require modeling of domain-specific events that are supposed to be interpreted by the user as highlights. Instead, we search for highlights at places where strong excitement is evoked in the user by the content of a video. It is namely realistic to assume that independent of the type of a highlighting event, each such event induces an increase in user's excitement. We mimic the changes in user's excitement by observing the temporal behavior of domain-independent audiovisual signal properties and the editing scheme of a video. Relation between these low-level features and the evoked excitement is drawn partly from psycho-physiological research and partly from analyzing the video generation practice. We evaluate our methodology on the excerpts taken from soccer TV broadcasts.
