摘要
根据各种数字加网的特性提出了各自最优的评价方法,并针对原始图像和加网图像在视觉上的不同,利用差别图像的统计特性,提出了一种基于加网算法和算法适应性的半色调图像质量评价方法。
In order to evaluate the halftoning algorithms and the corresponding halftones, a criterion is necessary. A series of halftonig algorithm-based methods are proposed, which adapt to the special properties of haltftoning algorithms. An adaptive method is proposed to evaluate the halftoning algorithms and the corresponding halftones, which is based on the statistical features of the residual image between the original image and the corresponding halftone on the retinal of human eye.
