Description

Pydrr is a python package for the damped rank reduction (DRR) method and its several variants. The DRR method has a variety of applications in both exploration and earthquake seismology, including but not limited to seismic denoising, seismic reconstruction, seismic diffraction separation, constrained LSRTM, constrained FWI, etc. The initial version of this package was held at https://github.com/chenyk1990/pydrr, which is no longer maintained.
