        im = StringIO(im)
    if not isinstance(im, Image.Image):

    im = im.resize((8,8),Image.ANTIALIAS).convert('L')
    avg = reduce(lambda x, y: x + y, im.getdata()) / 64.0
    return reduce(lambda x, (y,z): x | (z << y),
                  enumerate(map(lambda i: 0 if i < avg else 1, im.getdata())),
                  0)
