2D-log(KDE) plots showing the distribution of the areas and the three eccentricity metrics: (a) raw eccentricity (ellipse fitting), (b) convex eccentricity (computed on convex hulls), and (c) custom eccentricity (based on extreme points through the centre of mass of the segments). Each plot highlights the most probable eccentricity-area combinations and reveals trends.
