Demosaicing By Successive Approximation 

 

This page contains the experiment results with our new mosaicing algorithm [1]. It achieves at least comparable and often better performance than the current state-of-the-art color-filter-array (CFA) demosaicingtechniques [2],[3]. The 12 Kodak images used in this work can be downloaded as images.zip . The MATLAB implementation of our demosaicing scheme can be doaloaded from the following link: demosaic.zip
