Abstract
A method for processing seismic data from a subsurface using least squares migration or wave equation migration velocity analysis over a cost function comprising a function of a matching filter by iteratively updating the reflectivity model velocity model to yield an updated reflectivity model or updated velocity model that matches the observed seismic data.
