Abstract:
1. A method for determining whether a given event is a new event in a video stream comprising a plurality of events, comprising the steps of: extracting a first set of features from the given event, wherein the first set of features is computationally less expensive to process as compared to a second set of features associated with the given event; computing one or more first dissimilarity values between the given event and one or more previous events in the video stream using only the first set of features; and when one or more first dissimilarity criteria exist, determining whether the given event is a new event based on the one or more first dissimilarity values computed using only the first set of features; wherein existence of the one or more first dissimilarity criteria indicate that the one or more first dissimilarity values are sufficient to determine whether the given event is a new event.
