In this paper. according to the fundamental image processing method combining the property of wood anatomical structure image authors pointed out the method and theory which suit for wood anatomical structure image processing. In the two-value processing of wood anatomical structure grey image, the method of threshold value judgement and selection and image quality improvement was pointed out. At same time, this theory was applied in wood anatomical structure image processing, to measure wood cell space ratio and check cell molecular boundary. This theoretical method may provide theoretical fundament for wood growth ring analysis and forecast and special feature extract.

根据图象处理方法的基本理论,结合木材解剖构造图象的特点、提出了适合木材解剖构造图象处理的理论和方法。对木材解剖构造灰度图象的二值化处理过程中,最佳阈值的判定与选择,图象质量的改善等提出了具体的实现方法。同时将这一理论应用到长白落叶松入工林木材图象的处理中.测出了木材的胞壁率,对细胞分子的边缘进行检测。该理论方法可为木材生长轮材质分析、预测和细胞成份的特征提取提供理论基础。

The paper analyzed the wood anatomical feature and wood structure variation of Larix olgensis H. in man-made forest by computer vision technique. The analysis system of computer vision and the suitable analysis method of pattern processing on wood anatomical feature were both established. The accurate way for determining and choosing the optimal threshold value and improving the image quality in the grey image binary of wood anatomical feature were also given. The geometric sizes of wood molecules of Larix olgensis H. in man-made forest were measured. such as the outer and interior diameters of radial and tangential direction tracheid. the thickness of tracheid as well as the cell wall ratio in wood growth rings. etc This paper finally obtained the variation rule of the timber quality of growth rings and wood anatomical feature and structure of Larix Sogensis H. in man-made forest.
