The calculation of the local directions and radii is based on directional distance transforms and evaluation of the inertia momentsand axes of the resulring extremities of the centralized, directed chords. The method provides continuous results while minimizing the runtime byusing 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 tomographyTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo za stereologijo in kvantitativno analizo slike
