Select these parameters to compute the binary-weighted center of gravity of polygons formed by the outlines of the objects. The outline center of gravity is calculated by utilizing an integration method as oppose to pixel count. In general, the outline center of gravity differs from the pixel-based Centroid
due to the fact that the outlines are considered to be crossing the boundary pixels rather than encompassing them.

If the object contain holes, they are disregarded and do not affect the coordinates of the outline center of gravity.

CenterOutX
and CenterOutY are returned in calibrated units.
