Highly Effective Iterative Demosaicing Using Weighted-Edge and Color-Difference Interpolations

This page contains the image quality comparison of the state-of-the-art demosaicing techniques [1], [2] and ours [3]. Our algorithm achieves at least comparable and often better performance than the others. The 12 Kodak images used in this work can be downloaded as images.zip, which is downloaded from the website of the author [2]. The MATLAB source code of our algorithm can be downloaded from the following link: demosaic_su.zip.
