基于低冗余度曲波变换的三维地震信号处理
Three-dimensional Seismic Denoising Based on Low Redundancy Curvelet Transform
摘要
Abstract
Contamination of seismic signal with noise is one of the main challenges during seismic data processing.Based on sparse transform method,the seismic signals are sparse expressed in the transform domain.According to the different performance of signal and noise in the transform domain,threshold method is used to realize interpolation and denoising.A low redundancy 3D curvelet transform is introduced,and it is applied to interpolation and denoising of seismic signals.Numerical results show that the conversion is low redundancy,and the calculation speed is increased about four times when the curvelet transform has good numerical effect on seismic signal processing.关键词
