In many instances, it is convenient to label the space enclosed within the contour of a single-valued digital figure F. Labeling F by means of its distance transform DT, has been one of the first approaches to give structure to an otherwise amorphous space, and has been useful to reveal some of its features, especially those dependent on shape. In this framework, the set of the local maxima present in the DT plays a crucial role. In fact, the local maxima are necessary to identify the medial axis of F /1/. Moreover, figure decomposition techniques can be derived by suitably grouping the discs associated with the local maxima /2/.
