Abstract: Fast Fourier Transfer Image Processing was widely applied to the analysis of wood anatomy structure in recent years. The cells in the wood transverse section have obviously periodicity and regularity. FFT power spectral patterns can extract the periodic characteristics so that they can be compared,identified and classified quantitatively.This paper summarizes the application of FFT image analysis in wood science and the general way to study wood anatomy by FFT.
