程序代码说明 图像中的欧拉数是图像识别等的重要特征参数，本程序是采用matlab计算图像中的欧拉数(Code description of the Euler number of images is important, such as image recognition feature parameters, the procedure is calculated using matlab image Euler Number)

用MATLAB实现快速傅里叶变换。方程有需要的话，可以自己设定(Using MATLAB to achieve fast Fourier transform. Equation there is a need, they can set their own)

本设计采用了一种基于三参数组合的方法对语音信号进行了清/浊音判决。在传统两参数（短时能量和过零率）算法基础上增加了自相关函数作为判决参数，减少了清/浊音信号误判率。(This design uses a combination of methods based on three parameters of the voice signals of the Qing/voiced sentence. In the traditional two parameters (short-term energy and zero crossing rate) algorithm based on the increase since the correlation function as a decision parameter, reducing the clearance/voiced signal false positives.)
