Proposed method is based on Fourier transform which is in frequency domain displayed by high values of frequency components corresponding to major structural direction lines in the spatial domain image. The values of frequency components are summarized to directional vectors depending on certain angle and transformed to polar diagram and histogram. The polar diagram can be seen as an estimate of the rose of directions." . . "Analysis of Planar Anisotropy of Fibre Systems by using 2D Fourier Transform" . .
