Abstract
An event aware video system (EAVS) is to capture video frames during a first time period and process event portion of the video frames before transferring the processed data to a central computing system. The EAVS may establish a present no-event frame from the video frames, wherein a last frame of the video frames is marked as the present no-event frame if the difference between adjacent pair of frames of the video frames is less than a threshold value. The EAVS may establish an event frame, wherein a present frame captured after establishing the no-event frame is marked as the event frame if the difference between the present frame and a previous frame captured prior to the present frame is greater than the threshold value. The EAVS may generate the processed data by processing the event of the event frame.
