Application of Improved Wavelet Threshold De-noising Techniques in Seismic Signal Process
Research on the seismic signal process based on Wavelet Transform, Although the threshold method can remove random noise, the effect couldnt turn up trumps. So the weighted threshold combined soft and hard-threshold is adopted in the paper, the process results demonstrate that it can approach to signal preferably and restrain Gibbs oscillation.
