A multigrid approach to visual cortex mapping

David Herschel Smith

Abstract


Standard unconstrained optimisation methods, utilising conjugate gradient and limited memory reduced Hessian search direction updates, are implemented in a multigrid mode on an objective function minimisation model of visual cortex mapping. The multigrid operations, executed on a hierarchy of four grids, easily outpace fine grid iterations, and penetrate deeper into the objective function.
