Abstract:
1. A computer-implemented method comprising: calculating a first centroid or center-of-mass of a first contour extracted from a first image depicting a moving object as the object appeared at a first time; calculating a second centroid or center-of-mass of a second contour extracted from a second image depicting the object as the object appeared at a second time, the second image depicting the object in substantially the same plane as the first image; and displaying the first and second contours superimposed on a single display, with the respective first and second centroids or centers-of-mass positioned at a common location, wherein the displaying step includes displaying at least one identifying characteristic or feature for visually distinguishing the first contour from the second contour, wherein the step of calculating a first centroid or center-of-mass of the first contour and the step of calculating a second centroid or center-of-mass of the second contour each comprise the steps of: partitioned a polygon into a plurality of triangles each having three vertices: (x computing a centroid (x and summing the coordinates of each of the centroids, weighted by the area of each triangle.
