摘要
介绍3种细胞轮廓提取方法,提出利用链码技术提取细胞的边界轮廓信息。结果表明,该方法具有计算速度快和精确度高等优点。论述计算细胞周长、个数、面积、圆形度和重心等特征参数的多种方法,这些细胞特征参数可为木材材种识别提供重要的依据。
Automatic diagnosis of the wood assortment is the issue which needs to be solved urgently in wood industry. The wood assortment recognition that based on the lumber cell characteristic is a new research direction. The cell appearance is an important characteristic in the cell image analysis. And the cell characteristic parameter extracting is the foundation of wood assortment recognition. This paper introduced three cell outline extraction methods and proposed extracting the information of cell boundary outline using chain code technology which had the merits such as quick computing speed and the higher precision and so on. This paper also elaborated the some kinds of methods of computing the cell characteristic parameter such as cell perimeter, cell number counting, area, circular ratio and center of gravity and so on which provide the important basis for the wood assortment recognition.
