六、结构方法语言结构研究法把模式看成一些称为“字”或“词”的原始结构元素的组合,并且用句法或词法规则来定义这些字间的关系。这些原始结构元素应该是在感觉上或概念上比无向的度量更为高级的对象。例如,对于结构分析而言,如果在一张数字化图象中把各点的灰度级作为有意义的单位,就未免过于低级了;同样,也不应把一个数字化波形的个别振幅级当作有意义的单位。
VI. Structural Approach Language Structure Research treats patterns as a combination of primitive structural elements called “words” or “words,” and uses syntax or lexical rules to define the relationships between these words. These original structural elements should be objects that are more sensed or conceptually more advanced than undirected ones. For example, for structural analysis, it would be too low to regard the gray level of each point as a meaningful unit in a digitized image. Likewise, the individual amplitude levels of a digitized waveform should not be considered too low Meaningful unit.
