Abstract
This paper describes a simple method of description of the anisotropy of fibre systems using image analysis. The proposed method is based on Fourier transform which is infrequency domains displayed by high values of frequency components corresponding to major structural direction lines in the spatial domain image. The values of frequency components are summarised in directional vectors depending on their certain angle and transformed to a polar diagram and histogram. The polar diagram can be seen as an estimate of the rose of directions.
