提出ｈａｌｆｔｏｎｉｎｇ图像处理的一种新算法——匹配误差的扩散算法，它有效地消除了误差扩散算法的一些缺点．不仅如此，匹配误差的扩散算法也被用于多灰度级的ｈａｌｆｔｏｎｉｎｇ图像，结果表明有较好的视觉效果．
Proposed a halftoning image processing algorithm - matching error diffusion algorithm, which effectively eliminates some of the shortcomings of the error diffusion algorithm. Not only that, the matching error diffusion algorithm is also used for multi-grayscale halftoning images, the results show that there is a better visual effect.
