The research has been undertaken to analyze quantitatively the shape, dimension, and arrangement of wood structure which is consist of elements visible with nacked eye and microscope. The properties and structure of wood-based baords and pulp were also investigated in relation to the shape and configuration of the raw material. Additionally viaual images of wooden interior of residence were analyzed in a psychological aspect. Various image analyzing methods were used in the studies.1. Analyses of naked eye visible objects: (1) Quantitative analysis of shapes of round wood in order to decide most suitable sawing pattern for getting largest yield. (2) Quantiataive analysis of knots appering on conifer lumbers for distinguishing knot area and measuring three-dimensional grain angle surrounding knots by use of image processing methods. (3) Quantitative analysis of visual patterns appearing on wooden panels, and ratio of wood parts used in interior space in connection with the psychological images.2. Analyses of microscopically visible elements: (1) Stereo-analysis of hard-wood fibers in relation to elomgation growth of tress: quantitative analysis of arrangement of hard-wood tissues byoptical Fourier transformation. (2) Determination of contribution of individual wood tissues and cells on swelling anisotropy of wood in water and organic liquids by analyzing the optical microscopic images.3. Wooden raw materials in morphological aspects: (1) Sudies on effects of particle geometry and compaction ratio on properties of low-density particle board; effects of fiber shape and configuration on fiber alignment and properties of oriented medium density fiber-boards. (2) Quantitative evaluation of network structure of pulp sheets for estimating characterization of pulp; morphological analysis of relationbetween fibers and pigments in filler loaded sheets.

本研究以肉眼和显微镜下可见的构件为研究对象，对木材结构的形状、尺寸和排列进行了定量分析。还研究了原料形状和结构对木质纤维和纸浆性能和结构的影响。并从心理学的角度分析了几种典型的木结构住宅室内意象。研究中采用了多种图像分析方法.肉眼可见物分析：（1）定量分析圆木形状，以确定最佳锯切方式，获得最大产量。(2)应用图像处理方法对针叶材节疤进行定量分析，以判别节疤面积，并测量节疤周围的三维纹理角。(3)定量分析木质板材上出现的视觉图案，以及木质部件在室内空间中的使用比例与心理意象的联系.显微可见元素分析：（1）与木材生长有关的硬木纤维立体分析：用光学傅立叶变换定量分析硬木组织的排列。(2)通过光学显微图像分析，确定木材各组织细胞对木材在水和有机液体中膨胀各向异性的贡献.（1）研究了颗粒几何形状和压实率对低密度刨花板性能的影响;纤维形状和结构对定向中密度纤维板的纤维排列和性能的影响。(2)定量评估纸浆纸页的网络结构，以评估纸浆的特性;形态学分析纤维和颜料之间的关系，在填料加载纸页。
