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。

In this theory, we firstly introduce the basic theory of discrete wavelet transform and lifting scheme. Secondly, we adopt a fully pipelining VLSI architecture for lifting-based DWT. Hence, we can operate on higher working frequency. Besides, we merge a QCB-based DWT method to achieve the higher parallelism for JPEG 2000 encoding system. By changing the output timing of the DWT process, the internal tile memory size can be reduced by a factor of 4. Moreover, the architecture can efficiently perform shape-adaptive DWT and solve boundary extension and subsampling problems. Finally, according to the comparison results with other architectures, the efficiency of proposed architecture is proven.

在这篇论文中,首先我们介绍离散小波转换和提升式架构的基本理论,接下来我们改良提升式架构采用全管线化的硬体架构,因此我们可以操作在较高的工作频率,并且我们合并了以四个编码方块为基础的方式来使得JPEG 2000编码系统具有更高的平行度,藉著改变离散小波转换的输出时序,内部的记体体需求可以减少为原本的四分之一,接著此架构也可以有效地支援可适应形状的离散小波转换,同时解决了边界延伸和子取样的问题,最后根据与其他架构比较的结果,来说明所提出之离散小波转换架构的贡献。

This paper generalizes the conclusion of Perfect nonlinear S-boxes by Nyberg(1991), and introduces the conception of inverse regular generalized vector Bent function. It shows that for inverse regular generalized vector Bent function f with even variables, m is no more than half of?. It also shows that when the input dimension n is odd, the regular generalized vector Bent function and the inverse regular generalized vector Bent function do not exist. This may prevent the cryptology designer from seeking the inexistent function.

摘要该文完善并拓展了Nyberg(1991)的关于广义向量Bent函数性质的结论,相应于Nyberg给出的正则广义向量Bent函数,提出了&负则的广义向量Bent函数&的概念:得到有偶数个输入的负则的广义向量Bent函数输出维数也不大于输入维数的一半;证明了奇数个输入的正则和负则的广义向量Bent函数都不存在,这些结果的给出,可使密码设计者避免一味去寻找某类不存在的函数。

At first, setting up the arith relation between the signal input and the signal output of the generalized multi-carrier system of the Discrete Fourier Test spread-spectrum; then setting equilibria parameters of the frequency field equilibria subcarrier of the generalized multi-carrier system of the DFT spread-spectrum according to channel frequency response, channel noise variance and equilibria method; then calculating average power of useful signal, interferential average power between signals as well as noise variance of the generalized multi-carrier system receiving terminal of the DFT spread-spectrum according to the arith relation as well as the frequency field equilibria parameter, and recomputing available signal information noise ratio, so as to calculate the available signal information noise ratio of the generalized multi-carrier transmission system accurately, the method for estimating the available signal information noise ratio can be used for link self-adapting transmission solution of the generalized multi-carrier system based on Discrete Fourier Test spread-spectrum and radio material management.
