| 9:00 AM - 3:10 PM |
| Room 19 |
Details
All imaging and inversion algorithms leverage the same physics, acoustic/elastic versions of the wave equation, but it seems they cannot consistently utilise the full wavefield to improve results. The workshop explores underlying issues and whether they are caused by limitations in the input data, modelling, underlying theory, or something else.
