Paper Abstract

Ordered dither is a popular method for printing/displaying continuous tone images on bi-level devices such as laser printers, ink-jet printers and liquid crystal flat panels; the success of this algorithm comes from its simplicity and its non recursive nature. A major contention about this technique is its poor performance for rendering sharp edges. To alleviate this problem, we propose a new half-toning method called the dynamic ordered dither algorithm; it is an adaptive scheme based on the standard ordered dither operation preceded by an adaptive high pass filter. The dynamic ordered dither algorithm yields a far better edge rendition while keeping the good properties of the standard dithering process, namely the preservation of the object location, the good color reproduction and the possibility to use parallel archi-tectures for processing pictures in real time.
