摘要: 本文介绍了识别手写印刷体汉字的二维扩展属性文法(2-D EAG)方法中多义文法、共 生文法和结构推断三种识别控制机制.采用这些控制机制,2-D EAG方法可以在较大的幅 度内容纳结构畸变,可以利用相似结构之间的类比,实现先外后内的识别顺序,以及抑制冗余 识别.Abstract: This paper presents three kinds of control strategies, the polysemous grammars, the coexisting grammars, and the structure inferrings, realized in two-dimensional extended attribute grammar (2-D EAG) method for the recognition of hand written Chinese characters. With these control strategies, 2-D EAG method has higher tolerance ability to structural distortion. It makes analogy among similar structures, adopts the manner of "outline preference", and constraints redundant recognition.
