Abstract
The present invention is directed to a method for differentially processing image types within a document image to enhance the quality of on an image on a receiving medium. In one aspect of the invention, the method begins by receiving document image data including one or more image regions. The method determines for each image region whether the region includes any image data corresponding to a first image type.
