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。

This system mainly contains the front-end pulse interception and back-end software analysis. In the first part, we used a non-invasive infrared measurement method based on the dual channel simultaneous measurement technique. We measured the photo-plethysmograph from the subject's fingers and toes simultaneously, then used an analog circuit and central control unit to process the signals. Finally, the digital volume pulse data is processed by a personal computer. Because the characteristic points of digital volume pulse always occur in sharp variations, this paper proposes two algorithms to solve this problem. First, we find the pacemaker and percussion wave peak from transient slope variation, and then locate the dicrotic notch and dicrotic wave peak by using the wavelet transformation algorithm. When we analyze the data, we use the Visual Basic graphical user interface, which together with the Matlab is the core of the system.

本系统主要包含前端脉波撷取及后端软体分析两部分,其中前端脉波撷取部份是以非侵入式的红外线量测方式,双通道同步量测受测者手指与脚趾的光容积变化描记图,同时将此讯号经类比处理电路及中央控制单元输出成为数位容积波,再传送至个人电脑中;而在后端软体分析部份,因数位容积波之特徵点皆出现於波形中急剧变化的部份,故本论文以瞬间斜率变化量来定位脉波讯号中的起搏点及主波峰顶点,并利用小波转换演算法(wavelet transformation algorithm)来分析重搏切迹与重搏波顶点;程式撰写主要以Matlab为核心,结合Visual Basic的图形化使用者操作介面,增加系统与使用者间的亲和力。
