Mn. Pons et al., PARTICLE-SHAPE CHARACTERIZATION USING MORPHOLOGICAL DESCRIPTORS, Particle & particle systems characterization, 14(6), 1997, pp. 272-277
Two descriptors based on mathematical morphology are described which p
ermit 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 referen
ce shape. Three reference shapes are discussed: the convex hull, the c
ircle circumscribed to the particle and the equivalent circle.
