本文论述并设计实现了一个脱机自由手写体数字识别系统。文中首先对待识别数字的预处理进行了介绍，包括二值化、平滑滤波、规范化、细化等图像处理方法；其次，探讨了如何提取数字字符的结构特征和笔划特征，并详细地描述了知识库的构造方法；最后采用了以知识库为基础的模板匹配识别方法,并以MATLAB作为编程工具实现了具有友好的图形用户界面的自由手写体数字识别系统。实验结果表明，本方法具有较高的识别率，并具有较好的抗噪性能。(In this paper, and design implementation of a freely Offline handwritten numeral recognition system. First, identify the figure of the pre-processing treatment were introduced, including binarization, smoothing filtering, standardization, refinement, such as image processing method Secondly, to explore how to extract the structural features of characters and stroke characteristics, and described in detail Knowledge of the construction method Finally the use of a Knowledge-based template matching to identify methods and MATLAB as a programming tool to achieve with a friendly graphical user interface of freely handwritten numeral recognition system. The experimental results show that this method has higher recognition rate, and has better anti-noise performance.)

1.参数的设计 1）系统的变量比较多而且应用非常频繁，所以运用的变量要具有特征性 2）尽量使用课本上的变量，如果课本上的变量无法实现，在考虑其他自己定义变量 3）由于MATLAB使用变量可以不用先定义生命变量，所以可以直接使用变量 4）但是一些全局性的变量必须要定义( 1. Parameter design 1) system variables and the application is more frequent, so the use of the variable to have the characteristics of 2) the use of textbooks on the variables as possible, if the books can not be achieved on the variables, taking into account their other define the variable 3) use of the MATLAB variable life and variable can not be defined, so you can directly use the variable 4), but some global variables must be defined)

说明：  广义S变换 作为小波变换和短时傅里叶变换的继承和发展， S 变换采用高斯窗函数且窗宽与频率的倒数成正比，免去了窗函数的选择和改善了窗宽固定的缺陷，并且时频表示中各频率分量的相位谱与原始信号保持直接的联系，使其在 PQD 分析中可以采用更多的特征量，同时， S 变换提取的特征量对噪声不敏感，因此，近年来众多学者纷纷采用 S 变换并结合其他分析工具应用于 PQD 的分析，产生了大量研究成果。(Generalized S-transform)
