Abstract
Introduction:
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.
Methods:
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.
Results:
We show experimentally how the proposed algorithm gives in mean better reconstructions than more computationally expensive algorithms.
