Marmousi Example
- The top left: the migration velocity
- middle: the Dix velocity in depth
- right: the velocity estimated by our apporach.
- Bottom left: the prestack depth-migrated image with Dix velocities
- middle: the prestack depth-migrated image with our veloicites
- right: the angle domain common-image gather at 400 m using
- Left: Dix velocity
- Right: our velocity.
The angle-domain common image point gather (bottom-right) can serve as a test whether the estimated seismic velocity is correct. Horizontal lines ("flat events") indicate the correctness of the velocity. We see that our method flattens some events.
