摘要
在打印机上输出连续色调的图像,只能依赖于数字化半色调技术。提出了一种新的基于AM的误差扩散的算法,该算法结合调幅半色调技术和调幅半色调技术中的误差扩散法,在用可调节的较小的AM模板对图像进行半色调处理的同时,将原始图像与结果二值图像间的误差扩散到周围像素,使少数像素基本上按原始图像的灰度值分布。
Desktop printers such as laser and inkjet rely on digital halftoning in order to produce the illusion of continuous tone. This paper suggests a new generation of haftoning techniques, the error diffusion based on AM halftoning. After apply AM halftening with a small pattern to a continuous-tone image and making the error between the resulting image and origin image diffusion to neighborhood.
