Digital Screening Algorithm Based on Improved Delaunay Triangulation

This paper proposes an improved Delaunay triangulation algorithm for digital screening. The algorithm can give a real-time result for its high efficiency. It can give a good solution for Moire patterns phenomenon when printing in traditional pattern. Output image is accurate and soft since gray value distributes uniformly. It has a low request for equipment and subsequent handling, and entirely meet the needs of traditional printing technology.
