dc.description.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. Due to well estimating the interpolation directions based on reliable inter-channel correlation, the interpolation accuracy is guaranteed, besides, an effective post-processing was implemented to reduce the interpolation artifacts. As a result, compared with the latest demosaicking algorithms, experiments showed that the proposed method provides superior performance in terms of both objective and subjective image qualities.
