1. A method for processing a digital image, said method comprising: a) dividing an image into sections; b) estimating a complexity measure for at least one of said sections; c) determining a cumulative complexity measure that represents the cumulative complexity of sections upon which said estimating has been performed; d) repeating steps b and c until said cumulative complexity measure meets a criterion or until said cumulative complexity measure represents the cumulative complexity of all of said sections; and e) performing a first image enhancement process when said cumulative complexity measure meets said criterion.
