Fig. 3: Distributions of morphological parameters for LoFs, GEPs, and KHs.
From: Feature-based volumetric defect classification in metal additive manufacturing

Parameters include a max. axis, b aspect ratio, c sphericity, d solidity, e sparseness, f extent, g roundness, h elongation, and i flatness. Examples of each type of defects are also shown in the panels with the values of their morphological parameters pointed by triangles of respective colors. The fitted curves are Kernel Smooth for max. axis, while Weibull distributions are used for all other parameters.
