Figure 8.31 illustrates the multiscale watershed transform applied to a real
image. The decreasing sets of markers are obtained by applying the h-minima
filter; that is, the dynamics of the minima are used. We show a mosaic image
where the primitive catchment basins of the gradient are displayed with gray
level proportional to the dynamics of their regional minima. Then we show three
levels in the hierarchy, with markers taken as the regional minima with dynamics
above 3, 8, and 15. In Fig. 8.31, (a) is the input image, (b) is the morphological
gradient, (c) is the mosaic image, and (d), (e), and (f ) show the results of the
watershed transform from ...
