If you anticipate the algorithm is not general (can it work on any image,
will it only be useful to just a few ImageMagick users) it would probably
be best to implement it as an image filter.  Otherwise if it is best to
implement on the command line, we still need a description of the the
algorithm parameters to ensure the current ImageMagick command line parser
can readily handle your option requirements.
