Abstract:
A method for determining a value for an unknown pixel T, in which T is a selected pixel of an input image having an input image type, the method comprising:selecting an immediate neighborhood of pixel values and an extended neighborhood of pixels values; computing an average pixel value of the immediate neighborhood of pixel values; comparing said average pixel value to said immediate and extended neighborhood pixel values and determining a binary pattern based on the comparing; reducing the binary pattern and identifying a set of coefficients for the reduced binary pattern; providing plural lookup tables defined with respect to different image types; selecting a lookup table according to the input image type, said selected lookup table including the set of coefficients; and in parallel, for each of a selected transformation of a set of transformations: determining a transformed pattern by applying the selected transformation to the binary pattern, locating the transformed pattern in said selected lookup table, and matching the set of coefficients, according to the selected transformation, to each pixel of the immediate and extended neighborhoods.
