Abstract

In this paper, we present a novel color image Demosaicking algorithm. The algorithm consists of two steps: an interpolation step and a refinement step. The missing green color information is first interpolated by using the color channel difference. In the refinement step, a local weighted directional interpolation method guided by the pre-interpolated green channel is applied to refine the interpolation results along the determined interpolation direction. Lastly, post-processing is implemented to output the final Demosaicked full color image. Compared with the latest Demosaicking algorithms, experiments showed that the proposed method provides superior performance in terms of both objective and subjective image qualities.
