Various movies pertaining to Dimitri's research:
Imaging under rugged topography:
Comparison of velocity analysis for a gather with significant topography
after elevation statics and wave-equation datuming.
Here is a comparison of Canadian overthrust data migrated
after statics and after wave-equation datuming.
Imaging complex structure with first-arrival traveltimes:
Marmousi synthetic example of
standard migration, and my method.
Clic here to see how the image is made.
To understand why layer-stripping migration works so well,
take a look at a comparison of the
acoustic wavefield with first arrival traveltime contours.
Plumes: Response of time migration to lateral velocity variations:
Impulse response of depth modeling followed by time
migration in the presence of lateral velocity variation. The frames
go from undermigrated, to overmigrated.
First order theory of plume formation.
Anti-aliased Kirchhoff migration:
Near-offset section, standard migration,
Gulf of Mexico near-offset:
apperture limited and anti-aliased migration.
15 degree, 45 degree + 1/6 trick wavefield.
Menu of vplot movies for people at Xservers.
These are the same movies, but they are more fragile; however, if they work,
they offer better loop control.
