Claim 13:
14. The method of claim 13, comprising:
refining a scale of width of a perturbation in at least one direction subsequent to a determination that the quality of the second seismic image does not meet the threshold value;
updating the current velocity model with the updated current velocity model;
adding a third velocity perturbation to the current velocity model to generate a third perturbed velocity model;
generating a third image utilizing the third perturbed velocity model;
generating and assigning a third measure of quality to the third image;
determining whether the third measure of quality assigned to the third image is a third optimal measure of quality at the particular location of the current velocity model; and
updating the current velocity model utilized to generate the seismic image to generate a third revised velocity model utilizing the third measure of quality assigned to the third image when the third measure of quality assigned to the third image is determined to be the third optimal measure of quality at the particular location of the current velocity model.
