The color2gray, it is a color2gray algorithm, and I would recommend
increasing the number of iterations instead of increasing the number
of samples. Think of running it with a low number of a iterations as a
preview of the results of multiple iterations. (the method is work in
progress and we're rtring to keep the implementation simple, rather
than engineer ad-hoc noise reduction capabilities into it at the
moment.)
