摘要:Multiscale and multidirectional transforms were introduced to represent non-spiky reflectivity instead of assuming spiky reflectivity in the deconvolution problem. The study found that an alternative sparse shearlet coefficient can be used to accurately represent the non-spi...

摘要:In towed-steamer marine seismic acquisition, crossline data are fairly sparse which makes crossline wavefield reconstruction very difficult. Therefore, reconstructing the sparse wavefield becomes a fundamental and crucial step in seismic processing flow. Recently, compressed sens...
