We are given a set of video clips, each one annotated with an ordered list of actions, such as
“walk” then “sit” then “answer phone” extracted from, for example, the associated text script …

During the last years, the task of automatic event analysis in video sequences has gained an
increasing attention among the research community. The application domains are disparate …

To address the increasing demand for wireless bandwidth, cognitive radio networks (CRNs)
have been proposed to increase the efficiency of channel utilization; they enable the sharing …

The notion of" events" is extremely important in characterizing the contents of video. An
event is typically triggered by some kind of change of state captured in the video, such as …
