Abstract: Frames of video data from a surveillance system can be analyzed in near real time to allow for action to be taken based on the analysis. Task-based resources can be allocated to process each individual frame. Pre-processing can be performed to determine whether to analyze a given video frame. Each frame to be analyzed can be processed using at least one recognition algorithm to detect objects of interest, which can also be compared against corresponding data from earlier frames to determine relevant behaviors, moods, actions, or patterns of use. Each determination can have a corresponding confidence value. Information about the determinations and confidence levels can be analyzed to determine whether an action should be taken, as well as the type of action to take. Information for the determinations can also be used to apply tags to the video content to allow for searching and indexing of the video content.
