I illustrate the proposed algorithm with the Marmousi dataset.
I use a prestack split-step migration method with one reference
velocity. I demonstrate with zero-offset images and angle gathers
that the approximation of the Hessian with
adaptive filters gives a result comparable to least-squares migration
with fewer artifacts.
