The Leading Edge (2013) 32 (2): 146-153.
... and enable more complete imaging and interpretation of seismic geomorphology and stratigraphy. A “domain transform” (DT) is an interpretation-guided process designed to remove some or all structural deformation from a seismic volume. It improves the imaging of paleo-depositional systems by creating a volume...

... to interpret due to the effects of structure (such as faulting, folding, and rotation) obscuring the stratigraphic features of interest. Domain Transformation™ removes arbitrarily complicated structure from a seismic volume, It is an interpretation-guided 3D transform that creates a volume consisting...

... compiling, correcting, and transforming inputs to a representative set of features containing information relevant to the classification problem ( Guyon, 2008 ; Hastie et al., 2009 ). Classifier training usually requires the adjustment and selection of one or more parameters, specific to a given supervised...

... transform relations used to obtain the vertical gravity gradient from the horizontal gravity-gradient are special cases of the general gravity-gradient tensor relations in the Fourier transform domain. The special cases (i.e., the Hilbert transforms) can be derived from the general relations if the gravity...

... Atlantic opening. Basile et al. (2013) showed that no marginal ridge could be observed, at least in the eastern termination of the transform boundary and that its continental slope was, as along Côte d’Ivoire–Ghana, a steep and non-sedimented domain. The regional structural analysis of Gouyet (1988...

... was resolved here by introducing an alternative approach in resolution enhancement. Our method uses Gabor deconvolution (GD) combined with wavelet scaling. First, the seismic trace is transformed in the time-frequency domain using the Gabor transform. Subsequently, the Gabor magnitude spectrum of the seismic...

...Jianhui Li; Colin G. Farquharson; Xiangyun Hu ABSTRACT The inverse Laplace transform is one of the methods used to obtain time-domain electromagnetic (EM) responses in geophysics. The Gaver-Stehfest algorithm has so far been the most popular technique to compute the Laplace transform in the context...

...Roohollah Askari; S. Hossein Hejazi ABSTRACT We have developed the slant stacking approach in the generalized S-transform (GST) domain of seismic data for the estimation of the group velocity of the multimodal surface wave. We used two versions of the GST. The constant-scale GST uses a constant...

... is processed independently in the inversion. We tested a transform-domain sparsity promotion simultaneous multitrace impedance inversion method to address this issue. The approach was implemented through minimizing a data misfit term and a transform-domain sparsity constraint term that incorporates the (2D...

... in the Laplace-Fourier domain. The window function we adopt is defined as a product of a gain function and an exponential damping function. The Fourier transform of a seismogram windowed by this function is equivalent to the partial derivative of the Laplace-Fourier domain wavefield with respect to the complex...

...Wenkai Lu ABSTRACT I have developed an accelerated sparse time-invariant Radon transform (RT) in the mixed frequency-time domain based on iterative 2D model shrinkage in the time domain. I denote it as SRTIS. In the traditional sparse time-invariant RT in the mixed frequency-time domain, the sparse...
