Zhang-Wu Directional LMMSE Image Demosaicking

Abstract

Most digital cameras capture samples through a color filter array. At every pixel location, the camera observes one of either the red, green, or blue component. Demosaicking (or demosaicing) is the problem of using this incomplete information to estimate all three color components at every pixel. Zhang and Wu proposed an effective solution to this problem in "Color Demosaicking via Directional Linear Minimum Mean-Square-Error Estimation" [4]. Source Code ANSI C source code to produce the same results as the demo is accessible on the article web page https://doi.org/10.5201/ipol.2011.g_zwld. Future software releases and updates will be posted at http://dev.ipol.im/ ~ getreuer/code.
