Retrieving the leaked signals from noise using a fast dictionary-learning method

W Chen, OM Saad, YASI Oboué, L Yang, Y Chen - Geophysics, 2022 - library.seg.org
Most traditional seismic denoising algorithms will cause damage to useful signals, which are
visible from the removed noise profiles and are known as signal leakage. The local signal …

3D true-amplitude elastic wave-vector decomposition in heterogeneous anisotropic media

Y Chen, S Fomel - Geophysics, 2023 - library.seg.org
Wave-mode separation aims at separating the elastic wavefield into P-and S-wave modes in
each subsurface grid. Several wave-mode separation methods require the calculation of …
