    red=numpy.compress([False, False, True], img, 2)

    blue=numpy.compress([True, False, False], img, 2)

    red=192-red.clip(0,192)+64

    # Remove green and blue
    greenblue=numpy.minimum(192-green.clip(0,192), 192-blue.clip(0,192))
    col=(red-greenblue).clip(64,255)-64
    col=255-((col*1).clip(0,255))
    return col
