3D DIRECTIONAL MATHEMATICAL MORPHOLOGY FOR ANALYSIS OF FIBER ORIENTATIONS

By Hellen Altendorf and Dominique Jeulin

Abstract

In this paper we present algorithms for measuring local characteristics of random fiber systems. The calculation of the local directions and radii is based on directional distance transforms and evaluation of the inertia moments and axes of the resulting extremities of the centralized, directed chords. The method provides continuous results while minimizing the runtime by using few sampled directions. Furthermore several steps of improvement for the computation of orientation and radius information are presented. The algorithms are evaluated using synthetic data and applied to images of realmicrostructures obtained by computer tomography

Topics: directional distance transform, fiber networks, fiber separation, inertia moments and axes, local orientation, mathematical morphology, Medicine (General), R5-920, Medicine, R, Mathematics, QA1-939, Science, Q
