Description
  • Článek popisuje jednoduchou metodu popisu anizotropie vlákených systémů s použitím obrazové analýzy. Navržená metoda je založena na Fourierově transformaci, která se ve frekvenční oblasti projevuje vysokými hodnotami frekvenčních komponent odpovídající hlavním směrům v prostorové oblasti. Hodnoty frekvenčních komponent jsou sčítány pro směrový vektor v závislosti na určitém úhlu a následně vynášeny do polárního diagramu a histogramu. Polární diagram může být chápán jako odhad směrové růžice. (cs)
  • This paper describes a simple method of description of fibre systems anisotropy using image analysis. 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.
