Comment : The proposed decomposition of the contour produces no more DSS than the number of maximal segments. [Sketch] Each obtained edge can be extended into a maximal segment using the B(.) and F(.) operators. Let us now suppose that there exists two edges contained in a maximal segment, then at some point of the algorithm, these two should have been merged as their union is a DSS, as result we can injectively map each edge of the proposed decomposition into the set of maximal segments.
