A comparative study of data- and image- domain LSRTM under velocity-impedance parametrization
Pengliang Yang, Zhengyu Ji
Least-squares reverse time migration (LSRTM) is one of the classic seismic imaging methods to reconstruct model perturbations within a known reference medium. It can be computed in…
