Abstrakt		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 resulring extremities of the centralized, directed chords. The method provides continuous results while minimizing the runtime by using few sampled direcrions. 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 real microstructures obtained by computer tomography.
