Sep 1, 2014 · This paper deals with ground roll attenuation using double density and dual-tree complex discrete wavelet transforms.
Deighan and Watts (Deighan & Watts, 1997) improved the results of the ground roll suppression in the wavelet domain compared with the Fourier domain.
Double Density Dual Tree Dwt method has four wavelets and two scaling functions. Using this method, shot gather data decomposes to sub-scales, and each scale ...
It is possible to eliminate ground roll by applying one‐dimensional, linear frequency‐modulated matched filters.
Ground roll is a commonly found noise in multicomponent land-based seismic data, often contaminating signals of interest and reducing the signal-to-noise ratio ...

Wavelet domain ground roll analysis (WDGA) was used for finding ground roll energy in the wavelet domain; it is a substitute method for thresholding in seismic ...
Thus, the objective of this article is to present a brief analysis of the 2D Wavelet transform filtering technique and a case study applied to a real shot- ...
The double density dual tree (DDDT) discrete wavelet transform (DWT) method was used in this paper to attenuate noise in pre-stack and post-stack seismic data.
