We recently reported good results with our image interpolation algorithm, One-Dimensional Control Grid Interpolation (1DCGI), in the context of grayscale images. 1DCGI has high quantitative accuracy, flexibility with respect to scaling factor, and low computational cost relative to similarly performing methods. Here we look to extend our method to the demosaicing of Bayer-Patterned images. 1DCGI-based demosaicing performs quantitatively better than the gradient-corrected linear interpolation method of Malvar. We also demonstrate effective interpolation of full color images.
