Abstract--Most commercial digital cameras use color filter
arrays to sample red, green, and blue colors according to a specific
pattern. At the location of each pixel only one color sample is
taken, and the values of the other colors must be interpolated using
neighboring samples. This color plane interpolation is known
as demosaicing; it is one of the important tasks in a digital
camera pipeline. If demosaicing is not performed appropriately,
images suffer from highly visible color artifacts. In this paper
we present a new demosaicing technique that uses inter-channel
correlation effectively in an alternating-projections scheme. We
have compared this technique with six state-of-the-art demosaicing
techniques, and it outperforms all of them, both visually and
in terms of mean square error.
Index Terms--Bayer pattern, color filter array, demosaicing,
POCS.
