摘要:

提出了一个新的联合去马赛克和放大算法,适合于覆盖有彩色滤波阵列的单传感器数码相机. 该算法基于原始彩色滤波阵列图像中的局部梯度,估计插值方向,并一致应用于后续的去马赛克和放大过程中.实验结果显示,该算法显著优于其他现存的相似算法.

关键词: 去马赛克, 插值, 放大, 彩色滤波阵列

Abstract:

Applicable for digital cameras equipped with single-sensor covered with a color filter array (CFA), a new joint color demosaicking and zooming algorithm was proposed, the interpolation directions from the raw CFA image was estimated based on the local gradients. The estimated directions were exploited consistently in the demosaicking and zooming. Experiments show that the proposed algorithm is of good performance compared with the several recently published algorithms.

Key words: demosaicking, interpolation, zooming, color filter array
