SYSTEM AND METHOD FOR FAST ILLUMINATION-INVARIANT BACKGROUND SUBTRACTION USING TWO VIEWS

A method for eliminating errors in foreground object detection in digitized images comprises providing (1101) a reference camera and a secondary camera, vertically aligning each said camera with a baseline that is approximately perpendicular to a ground plane, wherein said reference camera is placed lower than said secondary camera, selecting (1104) a foreground pixel in a reference view of a first point in a foreground object, finding (1105) a conjugate pixel of the foreground pixel in a secondary view, using (1106) the foreground and conjugate pixels to determine an image base pixel of a base point in the reference view, wherein said base point is a point on the ground plane below the first point, and using (1107) the foreground and image base pixels to find a location where the ground plane is first visible.
