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, anti-aliased migration

+ Gulf of Mexico near-offset: apperture limited and anti-aliased migration.

Finite difference:

+ 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.
