%0 Patent %D 2009 %T System and method for fast illumination-invariant background subtraction ... %A Lim,Ser-Nam %A Mittal,Anurag %A Davis, Larry S. %E Siemens Corporate Research, Inc. %X A method for eliminating errors in foreground object detection in digitized images comprises providing 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 a foreground pixel in a reference view of a first point in a foreground object, finding a conjugate pixel of the foreground pixel in a secondary view, using 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 the foreground and image base pixels to find a location where the ground plane is first visible. %V 11/282,513 %8 2009/03/31/ %G eng %U http://www.google.com/patents?id=8yK_AAAAEBAJ %N 7512250
