Two descriptors based on mathematical morphology are described which permit discrimination between convex and concave polygonal shapes which often characterize crystalline particles. Their computation is based on the comparison between the silhouette of the particle and a reference shape. Three reference shapes are discussed: the convex hull, the circle circumscribed to the particle and the equivalent circle.
