Malvar-He-Cutler Linear Image Demosaicking

Abstract

Image demosaicking (or demosaicing) is the interpolation problem of estimating complete color information for an image that has been captured through a color filter array (CFA), particularly on the Bayer pattern. In this paper we review a simple linear method using 5 x 5 filters, proposed by Malvar, He, and Cutler in 2004, that shows surprisingly good results.
