This paper presents a new algorithm to extract the fetal ECG from an ECG recorded on the mother’s abdomen. The algorithm consists of two steps: first, ECG of fetus is extracted from the original signal using a two-level wavelet transform. We use Daubechie wavelet transform, which is similar in shape to heart beat wave. The resulted signal is then low-pass filtered using the Savitzky-Golay smoothing filter to attenuate the effect of noise. The filtered signal is considered as the fetal ECG. The algorithm was applied on both synthetic and real ECG signals. The results in this paper show that the proposed algorithm has promising performance.

说明：  这是matlab的otsu处理图象的算法，请高手们指正(This is the Otsu Matlab image processing algorithms, experts used the correct)

从已经出现故障的信号中，提取能够反映该信号故障特征的值，以后就能根据数值直接判断别的信号有没有出现该故障，更加直观(Signals the fault has appeared in the fault feature extraction and can reflect the value of signal, after can according to numerical directly to judge the other signals have appeared the fault, more intuitive)

MATLAB实现K均值聚类，自己编的，可用，不用系统函数。(MATLAB realization of K-means clustering, own, use, instead of the system functions.)

在matlab中将三维坐标转换成经纬度坐标或将经纬度坐标变成三维坐标(Matlab will be at three-dimensional coordinates into latitude and longitude coordinates or latitude and longitude coordinates into a three-dimensional coordinates)
