| Abstract: | To solve the problem of noise reduction in the magnetic flux leakage(MFL) signals better,the method based on the basic theory and characteristics of the lifting wavelet package transform was applied to decomposition and reconstruction of the MFL signals.Compared to the traditional wavelet package transform,this method has higher resolution and proximal optimization ability.The research results show that the lifting wavelet package transform not only retains effective composition in the original MFL signals,... |
