Abstract
A method is described for seismic imaging including receiving a full waveform inversion (FWI) image of a subsurface volume of interest including complex geology; transforming the FWI image to the Fourier domain to generate a Fourier domain image; performing a multi-dimensional low-cut filter of the Fourier domain image to generate a low-cut filter image; phase rotating by 90 degrees the low-cut filter image to generate a phase-rotated image; performing an inverse Fourier transform on the phase-rotated image to generate a transformed image; and displaying the transformed image on a graphical display. The method is executed by a computer system.
