摘 要: | 利用傅傅里叶变换图像处理技术来测定针叶材侧柏横切面早材细胞排列,把表示每一个细胞的半径为十个像素点的恻盘点图,进行傅里叶变换,再做能量光谱图的角度分布图,其最大值表示细胞的排列.通过傅里叶变换图像处理发现侧柏的细胞在斜向上的排列为15°.木材细胞排列参数为数字化识别木材提供了新依据,也为进一步分析其物理力学性质提供新的理论研究方向.

Analysis of Cell Arrangements in Biota Orientalis Using Fourier Transformation |
| |
Abstract: | Fourier transform image-processing technology is applied for determining the cross section cell arrangement of earlywood in Biota orientalis. In this method, the disc-convoluted dot map from each cell radius with 10 pixels is transformed by Fourier transform, generating the angle distribution function in the power spectral pattern. The maximum value is the arrangement of the cell. The results of Fourier transform image-processing technology indicated that the arrangements of the cell of Biota orientalis are 15° in oblique direction, respectively. This method provides a new basis for the digitized identification of the wood, and also the new theoretical research direction for the digitized identification and examination of the wood species. |
