Tarel prior and color ellipsoid relationship. Graphical example of the relationship between the image whiteness and color ellipsoids on the red-green plane. Examples of ellipsoid positions and orientations that are well approximated with measuring the minimum color component of the respective centroid are the clusters with dark ellipses. The dashed blue ellipse is an example of a cluster orientation where the approximation is not valid.
