A Fast Algorithm for the Demosaicing Problem Concerning the Bayer Pattern

Authors: Antonio Boccuto, Ivan Gerace, Valentina Giorgetti, Matteo Rinaldi

In this paper we deal with the demosaicing problem when the Bayer pattern is used. We propose a fast heuristic algorithm, consisting of three parts. In the first one, we initialize the green channel by means of an edge-directed and weighted average technique. In the second part, the red and blue channels are updated, thanks to an equality constraint on the second derivatives. The third part consists of a constant-hue-based interpolation. We show experimentally how the proposed algorithm gives in mean better reconstructions than more computationally expensive algorithms.
