Computation of granulometric curves for different regions of interest. a Result of the partition super-imposed on the original image. Three thickened polygons hightlight regions corresponding to specific tissues: parenchyma (red), rind (blue), vascular bundle (green). b Computation of granulometric curves for each region of interest. The complete collection of granulometric curves is shown as gray. The granulometric curves corresponding to the highlighted regions are shown in thick colored lines
