Suppressing seismic random noise based on non-subsampled shearlet transform and improved FFDNet

Frontiers in Earth Science
Traditional denoising methods often lose details or edges, such as Gaussian filtering. Shearlet transform is a multi-scale geometric analysis tool which has the advantages of multi-resolution and multi-directivity.
