Application of a Wavelet Extension De-Noising Method in Seismic Data Processing
Ye Wu, Bo Zhang, Jia Wei · Advanced materials research · 2012
A new wavelet extension de-noising (WED) method is proposed in this paper. The basic principle is derived in detail. We have removed the high frequency noise in seismic data based on the suppressing detail components method, Fourier transform filtering method, WED method and reconstructing the 5th layer approximate coefficient method respectively, and the results show that the WED method can more effectively restrain noise than the other methods.
