一种识别线划图形的方法

把模式识的统计方法和句法方法统一起来成为一种有效的方法,已经有过一些研究, 取得了进展.本文在作者用属性文法来统一两种方法的工作基础上,借鉴认知心理学关于记 忆和语言的一些论点,讨论了高维属性文法的句法和词意之间的折衷关系,对于线划图形,给 出句法、词义以及模块之间关系信息的距离度量,从而可以用最小距离准则来进行线划图形 (尤其是汉字)的识别.

A Line Drawing Pattern Recognition Method

The unification of syntactic and statistical approach has been investigated so as to get an officient metrod for pattern recognition. In this paper, based on the work done by the author, and referred to a point of view in cognitive psychology, the recognition of line drawing patterns is discussed. The trade off between syntax and semantics in high dimensional attributed grammar is shown by an example. In addition, the distance measures of syntax, semantics, and relationships between chunks are also given for line drawing pattern recognition. As a matter of fact, the minimum distance criterion can be applied for line drawing pattern (especially for Chinese character) recognition.
