Application of an unbalanced optimal transport distance and a mixed L1/Wasserstein distance to full waveform inversion

Da Li, Michael P. Lamoureux, Wenyuan Liao

Full waveform inversion (FWI) is an important and popular technique in subsurface earth property estimation. However, using the least-squares norm in the misfit function often lead…

Efficient and Stable Finite Difference Modelling of Acoustic Wave Propagation in Variable-density Media

Da Li, Keran Li, Wenyuan Liao

In this paper, we consider the development and analysis of a new explicit compact high-order finite difference scheme for acoustic wave equation formulated in divergence form, whic…
