	In the most recent SIGGRAPH Conference procceedings there is an
excellent algorithm called CCC which seems to fill your needs.  The only
drawbacks to the process is time needed to expand and image and the slight
aliasing created by the process....  I think this method has been discussed
recently on the net so I won't go into specifics.
