The objective function is maximized when the segmented membranes are just on the membranes. Embryonic region segmentations of a membrane image computed with different parameter sets. Red lines indicate the edges of the segmentation results. The value of the objective function is maximized when the edge locates just on the outermost membrane (a), and reduces when the edge locates inside this membrane (b). The value may again increase when the edge locates on the inner membranes (c). However this result is rejected because it violates the equality constraint (Eq. (5) that forces the embryonic regions to enclose all seed nuclei
