在彩色滤波器阵列去马赛克中，拉链效应和假彩色等伪影会降低恢复图像的质量。为了抑制这些伪影并恢复高质量的图像，本文提出了一种混合去马赛克方法。该方法包括两个连续的过程：一个重建过程，它采用了一些空间自适应方案，大大减少拉链周围的边缘区域的影响，和细化过程，它利用自适应中值滤波以及迭代校正的色差平面，以抑制假色。实验结果表明，所提出的方法优于现有的国家的最先进的方法，在视觉上和定量上，在各种各样的测试图像。
Artifacts such as zipper effect and false color degrade the quality of the recovered images in color filter array demosaicing. To suppress these artifacts and recover high-quality images, we propose a hybrid demosaicing method in this paper. The proposed method consists of two successive processes: a reconstruction process, which adopts a number of spatial adaptive schemes greatly reducing zipper effects around edges regions, and refinement process, which utilizes adaptive median filtering as well as iterative correction in color difference planes to suppress false color. Experimental results show that the proposed method outperforms existing state-of-the-art methods, both visually and quantitatively, on a large variety of test images.
