Bayer Image Demosaicking Using Eight-Directional Weights Based on the Gradient of Color Difference

Bayer Image Demosaicking Using Eight-Directional Weights Based on the Gradient of Color Difference

In this paper, we propose a new demosaicking algorithm which uses eight-directional weights based on the gradient of color difference (EWGCD) for Bayer image demosaicking. To obtain the interpolation of green (G) pixels, the eight-directional G pixel values are first estimated in red (R)/blue (B) pi...
