Inverse Halftoning Based on Discrete Sibson Interpolation
Author(s): 
Pages: 70-75
Year: Issue:  1
Journal: Acta Electronica Sinica

Abstract: 本文提出了一种基于离散Sibson插值的盲反半色调方法.算法建立在统一的离散Voronoi图框架之上,通过自适应Voronoi区域估计得到种子点的灰度值,然后通过离散Sibson插值将传统的反半色调问题转化为插值问题并计算获取连续色调图像.算法不需要知道任何先验知识,因此算法具有更广的适用性,可以被应用于任意方法生成的半色调图像的反半色调处理.在效果处理方面,算法能够很好的保留原始图像的信息,同时...
