1. A method for processing a digital image, said method comprising: a) dividing a non-object-based image data set into sections; b) performing segmentation on a section of said sections; c) estimating a complexity measure for said section based on the results of said segmentation; d) determining a cumulative complexity measure that represents the complexity of sections upon which segmentation has been performed; e) repeating steps b-d until all sections are segmented or until said cumulative complexity measure meets a criterion; f) terminating said method and performing a first image enhancement process when said complexity measure meets said criterion; and g) performing a second image enhancement process when said complexity measure does not meet said criterion.
