Description: |
In seismic exploration a wave field is generated at the surface and reflections from the earths interior are recorded. The purpose is to find properties such as wave velocity and location of reflecting sub layers. This can be in an inverse problem where the measurements are compared to a computed wave field with unknown coefficients in the wave equation. We will discuss two aspects of this process. One is the fast computation of the wave field and the other the choice of metric in the comparison between the measurements and the computed wave field. We propose Wasserstein metric for the comparison. We will also comment on the closely related technique of ultrasound medical imaging.
