蓝噪声与绿噪声数字半调技术原理分析与比较

Analysis and Comparison of Blue-and Green-Noise Digital Halftoning Methods

用空间点统计和频谱分析的方法对蓝噪声和绿噪声数字半调原理进行了研究,讨论了二者在某个灰度级处少数点之间的相互影响方式,分析比较了二者之间的关系以及基于这两种方法产生的图像特点及适用性。

This paper studies blue-and green-noise digital halftoning methods in spatial and spectral domain,discusses effects among minority dots in the halthoning images based on the two methods,analyzes and compares the relationships and image characters between the two methods,and finally points out their applications in different cases.
