ABSTRACT:
The present invention is related to a method for processing a digital image, wherein the digital image comprises at least a gray-scale component. The method may comprise: morphologically filtering the grayscale component to produce a segmentation result; low-pass filtering the gray-scale component under control of at least the segmentation result to produce an image mask; and enhancing tone reproduction of the digital image utilizing at least the image mask.
