Abstract Digital cameras sample the continuous spectrum using an array of color filters such that each pixel samples only one color band producing what is commonly referred to as a color mosaic. Demosaicing the image simply converts a Bayer pattern encoded image to a truecolor (RGB) image using a demosaicing algorithm of some kind. sensor modeling, color processing and color reproduction evaluation. ORIGINAL ARTICLE Color image demosaicing using sparse based radial basis function network V. When demosaicing a pixel which lies at the top edge of the raw image, there are no pixels above it, thus it cannot be demosaiced in the same way and at the same quality as those pixels which are surrounded by a sufficiently large number of pixels. We will also share demo code in C++ and Python. The image above (figure 2) was created by a raw file analysis application called RawDigger with a simple demosaicing algorithm that has artifacts: Notice the false colours (the subject was purely black and white) and repeated faint on/off patterns introduced along a row.
