Seismic Data De-noising Based on Wavelet Thresholding
Weilong Wu · Science Technology and Engineering · 2010
De-noising of seismic data is a main task of geophysical exploration,improving thesignal-to-noise radio is turning to more and more important accordingly.The threshold is selected by Heursure method and soft threshold function,launches process of second-decomposition on wavelet layer quantification to test signal,synthetic seismic signals and practical seismic data.Compared with conventional wavelet threshold de-noising,this method has more advantage on de-noising to the signal containing high frequency components.
