采用小波相邻系数降噪，然后用改进的局域均值分解对滚动轴承进行特征提取，得到特征向量-Using adjacent wavelet coefficients of noise reduction, and then use the improved local mean decomposition characteristics of rolling bearing are extracted, get the feature vector

局部均值分解程序，可根据信号本身的信息进行自适应分解，用于信号数据或图形数据的分析处理。(The local mean decomposition program can be adaptively decomposed according to the information of the signal itself, which is used for the analysis and processing of signal data or graphic data.)
