Dictionary learning noise
WebApr 5, 2024 · Seismic wave acquisition is usually disturbed by natural noise and instrument noise. As the seismic wave propagates, the filtering effect of the Earth and its various layers will result in energy attenuation and velocity dispersion; these phenomena weaken the seismic time series amplitudes and distort the seismic phase data. In traditional … WebOct 6, 2024 · Request PDF Data-driven multi-task sparse dictionary learning for noise attenuation of 3D seismic data Representation of a signal in a sparse way is a useful and popular methodology in signal ...
