    3535<p> The idea behind error diffusion is to compute the error caused by
    36 thresholding a given pixel and propagate it to neighbour pixels to
     36thresholding a given pixel and propagate it to neighbour pixels, in order to
    3737compensate for the average intensity loss or gain. It is based upon the
    3838assumption that a slightly out-of-place pixel causes little visual harm.
