一种适合于描述无限制手写字符图像的语言CPDL
A Language CPDL Suited for Describing Un-Restricted Handwriting Character
【摘要】 人们曾为解决特定的识别问题提出了许多图像描述语言,但至今还没有任何一种能有效地克服手写字符的形状差异对句法识别的影响。本文在K.S.Fu的形状属性文法的基础上,进一步发展了一种带有位置和形状属性的文法。它只需7个简单的模式元,句子的长度可以人为地加以控制。这种语言的优点是:具有较强的描述能力及灵活性,能有效地克服形状的各种变化对句法识别的影响。
【Abstract】 Based on K. S, Fu’s shape attribute grammar, this paper develops a grammar with position and shape attributes. It needs only seven simple primitives, the sentence length can be controlled artificially. The merits of this language are: stronger descriptive ability and feasibility. It can effectively reduce the influence of the shape variation on syntactic recognition.
