1. A method for utilizing a motion detection/characterization utility linked to a computer or loaded on the computer operable to perform detection and/or characterization of motion of a target, said method comprising the steps of: a. capturing a series of time lapsed images of the target, wherein the target moves as between at least two of such images; b. generating a motion distribution in relation to the target across the series of images, said motion distribution being generated by: defining a region of interest for each of the at least two images that corresponds to the target, or movement of the target; comparing the region for each of the at least two images to establish the difference therebetween; estimating the level of activity associated within the region for each of the at least two images; and based on the level of activity determining whether the level of activity connotes motion within the region, or motion having particular characteristics within the region; and c. identifying motion of the target based on analysis of the motion distribution.
