Abstract
Color images acquired through single chip digital
cameras using a color filter array (CFA) contain a mixture
of luminance and opponent chromatic information that share
their representation in the spatial Fourier spectrum. This
mixture could result in aliasing if the bandwidths of these
signals are too wide and their spectra overlap. In such a
