Speech-Enhance

自编的几个关于数字信号基本运算的程序，由此可以大大扩展信号运算的自由性与简洁性。(wrote several digital signal on the basic operations procedures, It can be greatly expanded signal operation and the freedom of simplicity.)

说明：  离散系统的差分方程，该程序可以得出差分方程！结果挺好的！(equation)

利用VC和Matlab混合编程,Release文件夹下可直接运行，绘出2D和3D图形。并且可以在VC 6.0环境下调试，注意文件夹中的readme文档说明。(Using VC and Matlab to program, Release folder can be run directly, draw 2D and 3D graphics. And it can debugging in VC 6.0 environment, pay attention to the folder readme documentation.)

利用小波分解的方法进行语音信号的降噪处理，适用于语音增强领域(The wavelet decomposition method is used to denoise the speech signal, which is suitable for the field of speech enhancement.)

Decision region vector For the decision region Number of bins for the data Percentage of incorrectly assigned samples at a nod Unknown command option This function recieves a parameter vector and returns it s components The parameter vector is completely numeric. This is much simpler Percentage of incorrectly assigned samples at a node

说明：  该程序是锁相环的MATLAB的简单实现程序，从中可以看到锁相环的基本功能的实现。(This program is a simple phase locked loop of MATLAB implement programs, from which you can see the basic function of phase-locked loop of implementation.)

voice activity detection using pre-emphasize energy ratio

将一幅图像转化为二值图像，然后对二值图像进行行程编码。(Will be an image into a binary image, and then carried out on the binary image encoding trip.)

本程序实现汉字和字符的识别匹配，通过该算法，可以实现手写体的字符和汉字的识别(This procedure to achieve identification of characters and character matching, through the algorithm, can achieve the character and Chinese character handwriting recognition)

这是HMM模型的matlab编程的使用方法，很全面的，欢迎大家下载。(HMM)
