Abstract
A method for moving object detection, comprising generating a time series of multi-exposures of scenes, each multi-exposure of a scene comprising a sequence of at least two at least partially overlapping images of that scene captured in rapid succession, wherein the time series of multi-exposures periodically revisits substantially the same scenes, detecting moving objects within each multi-exposure by comparing its sequence of overlapping images, and tracking objects by comparing moving objects detected within multi-exposures of substantially the same scenes.
