First scanning the known handwriting materials then number them ,In pretreatment, we convert the valid part of the image into a standard size, as images carries out duotone and go throw off chirp handling in order to achieve better effect.draw features from the known handwriting materials with the Co-occurence,especially,we divided a copy of handwriting into 25 little pieces with the size of 128*128 ,drawing features from every little piecese with four directions(0 degree, 45 degrees, 90 degrees as well as 135 degrees) and calculate the four major feature values( veins and the statistical quantity of veins contrast and the statistical quantity of veins consistency Shang the statistical quantity of statistical quantity as well as the veins correlation of gray scale ), preservation all the feature value that drawn from all known ma terials to the handwriting characteristic database,then input the unknown handwriting materials, also using the method of the Co-occurence to draw those features, recycling the minimum European Distance law match the unknown writing material feature value with the handwriting characteristic feature database, export the label of the known hand writing materials which is most similar to the unknown material with minimum European Distance, and then we can confirm who is the author of the unknown material.

首先将笔迹材料作为图象扫描输入，并对其进行编号。预处理部分可将笔迹图象的有效部分规范化到一个统一尺寸，接着对其进行二值化和去除噪声的处理，以便于更好的提取图像的特征。在此我们采用了灰度共生矩阵法提取手写笔迹材料的纹理特征，与以往有所不同的是，我们将一份手写材料分割成64块大小为80*80象素的子图象，每个小块都从四个方向（0度、45度、90度以及135度）来更全面的提取特征，并计算出四个最主要的特征值（纹理一致性的统计量、纹理反差的统计量、纹理熵的统计量以及纹理灰度相关性的统计量），将从所有已知材料提取的特征值保存到纹理特征库中，对于待检手写材料，同样采用灰度共生矩阵的方法提取其纹理特征，再利用最小欧氏距离分类法将从待检手写材料中提取的特征值与纹理特征库中的特征值进行比对，与欧氏距离比对值最小的相匹配，输出匹配成功的原材料的标号，进而识别出待检材料书写者的身份。

With the analysis of the framework of MDA and categorization research on all kinds of model transformation methods and languages in existence, analyzing the applications of OCL in MDA considering the characteristic of OCL, three directions is emphatically studied in this paper:First of all, according to the declarative characteristic of OCL, this paper proposes a hybrid model transformation language named Hybrid-OCL by extending OCL from three aspects, the syntax and semantics is also defined. Hybrid-OCL can describe dynamic semantics, store model transformation information in order to support model transformation synchronization, and provides the integrated model transformation program framework.

本文以MDA整体框架为起点，分类研究了现阶段各种模型转换方法和模型转换语言，结合OCL的特性分析了其在MDA框架中的应用，并在此基础上重点研究了以下三方面内容：首先，根据OCL声明式语言的特点，选取三个角度对其进行扩展，从而设计产生了混合式模型转换语言Hybrid-OCL，详细定义了其语法和语义，并通过具体转换实例验证了这种扩展的可行性。
