Claim:
1. A method of analyzing seismic image data, comprising: receiving a first image, the first image representing image data of a geological structure obtained from seismic receivers in a first position relative to the geological structure; receiving a second image, the second image representing image data of the geological structure obtained from seismic receivers in a second position relative to the geological structure, wherein the first position and the second position are in different physical locations with respect to the geological structure; measuring relative shift of the second image as compared to the first image with respect to the geological structure, wherein measuring relative shift of the second image as compared to the first image comprises performing a direct image domain comparison of the first image with the second image through a local image space correlation without computing common-image gathers; and based on the direct image domain comparison, estimating a velocity model of the geological structure.
