cython写的DTMF解码器（python直接使用，效率和c接近）

利用最小二乘法进行曲线的拟合,这是用多项式拟合曲线的源码!-using the least-squares method of curve fitting, which is the polynomial curve fitting source!

很有用的源代码，只是我好不容易找的哦，担不是我自己写的。-very useful source code, I finally find a just, um, fetching than I wrote it myself.

这个是纯C写的连通域提取算法，速度和效率相对较快，在算法中采用了八领域的关系来确定是否是同一个连通域，有用的朋友可以自行下载，可以用于自己的工程当中。
