摘要
针对图像再现技术中一个活跃的研究领域——数字半色调技术进行了综述.分析了数字半色调技术的发展现状;基于图像再现系统的基本结构和结果图像的特点,对经典的半色调方法进行了评判.最后展望了数字半色调技术的发展趋势,并指出一种基于图像特征信息的数字半色调技术实现的技术思路.
A review of digital halftoning techniques which are active area of research in image rendering is presented. Its present situation is analized in this paper. Based on the structure of image rendering system and the nature of the appearance of resulting patterns, the classical methods of digital halftoning are evaluated. The tendencies of digital halftoning techniques are described, and a new route of digital halftoning technique based on the nature of image is proposed.
