  • selecting a set of neighboring pixels surrounding an identified pixel;

    for each pair of pixels within said set, where pixels in each pair are on opposite sides of said identified pixel, determining an average value of the pixels of the pair;

    for each pair of pixels, calculating the difference between said identified pixel value and said average value of the pixel pair;

    for each pair of pixels, comparing the difference value to a predetermined threshold value; and

    incorporating at least one average value into a denoised identified pixel value based on the comparison.
