| Abstract: |
A high-efficiency and contrast-enhanced halftoning approach is presented in this article. The contrast of digital image depends highly on the nature of the ambient lighting and the quality of the lens. The required processing time skyrockets when a high printed work of high resolution and quality is needed. In this article, we use the benefits of high-speed ordered dithering and high-quality error diffusion to simultaneously solve the problems described earlier. Experimental results demonstrate that this technique is able to enlarge the dynamic range of the histogram and achieve improvement in execution efficiency of 15–47% with the tested images. © 2009 Wiley Periodicals, Inc.
