Constructing Table-of-Content for Videos

A fundamental task in video analysis is to extract structures from the video to facilitate user’s access (browsing and retrieval). Motivated by the important role that Table-of-Content (ToC) plays in a book, in this chapter we introduce the concept of ToC in the video domain. Some existing approaches implicitly use the ToC, but are mainly limited to low-level entities (e.g. shots and key frames). The drawbacks are that low-level structures (1) contain too many entries to be efficiently presented to the user; and (2) do not capture the underlying semantic structure of the video based on which the user may wish to browse/retrieve.
