Figure 7 Claerbout's ``qdome'' synthetic model.
Figures 7 and 8 show Claerbout's ``qdome'' synthetic model Claerbout (1993, 1999) and its corresponding slope estimates. In a missing data interpolation experiment, I remove 75% of the traces in the original model, arriving at the missing data model, shown in the left plot of Figure 9. The missing data interpolation result is shown in the right plot of Figure 9. Most of the original signal, except for some high-curvature areas, has been restored. Local 3-D plane-wave predictors allow us to use the efficient interpolation technique of Fomel et al. (1997), based on recursive filter preconditioning.
