摘要
Digital images that are produced by an image forming device may be processed using an edge enhancement technique to reduce the effects of halftone color depth reductions. For each element in the original image, certain detail elements are classified by examining the magnitude of pixel intensity gradients between elements of interest in a first window applied at each element and other elements in the first window. If a first predetermined condition is satisfied, those elements locations are stored. After halftoning, a morphological filter may be applied to the same element locations in the halftone image to enhance the halftone image.
