Most demosaicing approaches often introduce false colors or blur edges to areas of the image where there are dense edges. In this paper, we present a directionally weighted color interpolation method to address this problem. We consider finer edge orientations to improve the accuracy of edge indicators and exploit the inter-channel correlation of R, G, and B color planes in the interpolation process to reduce the undesirable artifacts and hence improve the perceptual image quality. Experimental results are shown to demonstrate the strengths of the proposed method. © 2005 IEEE. |
