Abstract:
1. A method of real-time new event detection to capture new-event video clips that present previously unseen events in a video streaming environment, the method comprising the step of providing a multi-stage sequential filtering process, the process comprising steps of: identifying relevant features; ranking the features based on computational effort to derive or extract the features; and forming one or more multi-stage sequential filters based on the ranked features, where more easily computed features are used before less easily computed features, and the multi-stage sequential filters are used to identify the captured new-event video clips in the video streaming environment; wherein text features alone are used to filter out a majority of non-new-event clips, so that image feature extraction on these clips is avoided; and wherein the steps are performed by at least one processor device coupled to a memory.
