DOI: 10.1016/j.jappgeo.2019.05.005
Abstract: Abstract In seismic exploration, suppressing random noise is a key step in improving the signal-to-noise ratio (SNR) of seismic data. The effective structures of seismic profiles can be characterized by the abundance of self-repeating patterns.… read more here.
