ESTIMATING MOTION OF AN EVENT CAPTURED USING A DIGITAL VIDEO CAMERA
摘要:
An event aware video system (EAVS) is to capture video frames during a first time period and process events in the video frames before transferring the processed data to a central computing system. The EAVS may establish a no-event frame by marking a last frame as the no-event frame if the difference between adjacent pair of video frames is less than a threshold value. The EVAS may mark a present frame captured after establishing the no-event frame as the event frame if the difference between the present and a previous frame is greater than the threshold value. The EAVS may provide event information to the central computing system by performing temporal blending, which includes linearly combining the movement of objects within the moving object in adjacent event frames to generate blurred images. The difference between the blurred images may represent displacement of objects moving within the moving object.
