说明：  做傅立葉轉換並SHIFT 2階巴特沃斯 做週期性雜訊的處理(Fourier transform and SHIFT 2 do Butterworth deal to do periodic noise)

说明：  基于短时能量 短时过零率 自相关函数的语音清浊分类算法(Zero based on short-term rate of short-term energy autocorrelation function of speech voicing classification algorithm)

一个小而有效的程序来执行的K -近邻搜索算法，此算法利用JIT 理论加速循环，比向量化有效解决了大量数据的精度问题。甚至比kd-tree效果要佳(A small and effective procedures to implement the K- nearest neighbor search algorithm, this algorithm uses JIT acceleration cycle theory, than to solve a lot of data to quantify the accuracy of the problem. Even more than the kd-tree effect has to be good)

这个是基于角点的匹配和拼接的MATLAB算法程序，如果有用得到的，可以参考！(is based on the corner of the match and combinations of MATLAB algorithm procedure, if the useful, reference!)
