Abstract
There is provided a method for analyzing an image of rod-shaped particles, the method comprising: transforming a spatial domain image of rod-shaped particles having random orientations to a frequency domain image thereof using DFT (discrete Fourier transform); extracting connected components from the frequency domain image using a frequency domain filter, wherein the connected components have a predetermined orientation; and back-transforming the frequency domain image having the extracted connected components to a spatial domain image thereof using IDFT (inverse discrete Fourier transform).
