Cell wall directions of tracheids in transverse sections of Agathis sp. and Cryptomeria japonica and fiber bodies in Magnolia obovata were quantified by Fourier transform image analysis (FTIA). Three kinds of information about cell shapes were determined from the angular distribution functions of the net map-power spectrum pattern (NM-PSP): (1) the peak angle expresses the most frequent cell wall...
Periodic cell arrangements of tracheids in Cryptomeria japonica and Agathis sp., and that of wood fibers in Magnolia obovata were examined by Fourier transform image analysis (FTIA). The angular distribution functions on power spectral patterns (PSPs) transformed from the dot maps were traced. As well as this conventional method, we developed the line convolution method and domain transformation for...
