Color Image Restoration Technique Using Gradient Edge Direction Detection

To achieve commercial cost effectiveness, most digital cameras use a color filter array (CFA) to capture images with a single charge-coupled device (CCD) sensor array, resulting in a sub-sampled raw image with a single red (R), green (G), or blue (B) component for each pixel of the image [1], [2]. To rebuild a full color image from the raw sensory data, a color interpolation using neighboring samples is requested in order to estimate the two missing color components for each pixel.
