| 摘 要： | 基于波峰、波谷的支配与从属关系,对具有自嵌套结构的波形提出了一种特征层次树描述方法,并建立了相应的波形分类系统.给出了作为树结点的主导峰(谷)的概念及识别算法,和波形特征层次树的生成算法及树结点的表达方式,分析了特征层次树的表达特点,还讨论了波形分类系统中基于这种表达方法的两种分类算法.

| Abstract: | An approach to the hierarchical representation of self-embedded waveform by a feature tree based on peak dominance relations is proposed and a waveform parsing system is described. The concept of dominance peak,as the tree nodes ,and its recognizing algorithm,are given. The algorithm for tree generation,the expression for the tree node and the properties of the tree are discussed. Two parsing algorithms based on feature hierarchical tree representation are suggested. |
