Orientation, sphericity and roundness evaluation of particles using alternative 3D representations [PDF]

, 2014
Sphericity and roundness indices have been used mainly in geology to analyze the shape of particles. In this paper, geometric methods are proposed as an alternative to evaluate the orientation, sphericity and roundness indices of 3D objects.
