Demosaicing using Human Visual Properties and Wavelet Interpolation Filtering
  DOI :  10.2352/CIC.1999.7.1.art00047  Published OnlineJanuary 1999

New color signal demosaicing algorithms in digital cameras are introduced by using properties of the human visual system, and by analyzing the desired frequency response of the interpolation filters. A color transformation of the RGB signal is used to obtain new signals on which interpolation is performed. The transformation corresponds to the signal processing steps within the human visual system. Wavelet filters are used for interpolation. Both objective measure and subjective testing show that the proposed algorithm achieves advantages over a previously published algorithm.
