BinaryOutlining  Method

Description         Binary outlining of an object is the process of changing all of an object’s pixels to the background graylevel value except those pixels that lie on the object’s contour. The function works for only 1 bit per pixel images. Binary outlining is defined as the eroded image substracted from the original image (inner contour) or the original image substracted from the dilated image (outer contour).
